CADOCHAMOUSSETIA: FROM RUSSIA WITH LOVE

From Russia with love. This lovely inflated ammonite is the female macroconch, Cadochamoussetia tschernyschewi (Sokolov, 1912) from the Jurassic, Lower Callovian, Elatmae Zone, Subpatruus Subzone, Stupachenkoi Horizon, Unzha River, Makarev-Manturovo, Kostroma Region, Russia.

This beautiful — fully Бомба — specimen is courtesy of Emil Black and one of the finest in his collection. 

It has a chunkiness that reminds me of the Cadoceras we find in the Pacific Northwest, particularly the macroconch Cadoceras comma from the Callovian Mysterious Creek Formation near Harrison Lake in British Columbia.

In the last decade, the Siberian zonal scale of the Callovian has been considerably revised because of new ammonite collections from the Callovian reference sections in Siberia. Species of Cadoceratinae thought of as exclusively European were recorded for the first time in Siberia. 

Both these newly recovered specimens and recent studies have considerably expanded our knowledge on the taxonomic composition of genera and species of Callovian ammonites and revision of the generic classification and stratigraphic position of genera and species of the family Cardioceratidae. The proposed Lower Callovian ammonite scale largely coincides with the East European scale and correlates with the scales of East Greenland, Arctic Canada, and Alaska (Kniazev et al., 2009, 2010, 2011, 2015; Nikitenko et al., 2013).

Jurassic deposits crop out on the right bank of the

Anabar River between the mouths of the Srednyaya

and Sodiemykha rivers, over a length of about 24 km.

During recent fieldwork at the Middle-Upper Jurassic of the Anabar River basin, a lovely representative ammonite collection was assembled, amongst which was the Early Callovian genus Cadochamoussetia (Mitta, 1996). 

Cadochamoussetia is widespread in East European sections but these beauties were the first recorded specimen of this chunky species from the Anabar.

The genus Cadochamoussetia (Mitta, 1996) was established in European Russian (Gerasimov et al., 1996) and later in England (Navarro et al., 2005).

In the lower Callovian of European Russia, beds with Cadochamoussetia were originally considered part of the Cadochamoussetia subpatruus upper subzone of the Cadoceras elatmae Zone (Mitta, 2000). 

In 2005 and 2009, proposals were made to move these beds from subzone to zone (Gulyaev, 2005, 2009). However, the Unified Regional Stratigraphic Scheme of Jurassic Deposits of the East European Platform (2012), suggested it remained a subzone. The Anabar section contains two species of Сadochamoussetia, which were used as the basis of the Сadochamoussetia tschernyschewi Zone.

In previous papers (Kniazev et al., 2010), considered the composition of the genus Cadoceras as it was interpreted in (Treatise, 1957). 

Several groups of species are now recognized within the genus: Cadoceras elatmae group, including C. frearsi, C. harveyi, C. sublaeve, including species widespread in the Arctic C. tolype, C. emelianzevi, C. septentrionale, C. durum, etc. 

Kniazev et al. proposed assigning a group of Bathonian species Catacadoceras laptievi, C. barnstoni, C. perrarum, C. subcatastoma, and C. nageli.

Photos: Cadochamoussetia tschernyschewi (12 cm) graciously shared by the deeply awesome of Emil Black. He has shared many wonderful specimen photos and stories with me over the years and I am honoured by his generosity in doing so. It is because of him that I am able to share these with all of you! So a collective, Спасибо, мой друг. Spasibo, moy drug. 

I have placed views of this lovely Cadochamoussetia tschernyschewi into a teaching tool that includes the specimen name, length and provenance.

TRACKING THEROPODS HIGH IN THE PERUVIAN ANDES

Left, right, one, two... Theropod Tracks

Left, right, one, two... the wonderfully preserved theropod trackway you see here was found by eagle-eyed construction workers blasting out a tunnel for a road near Yanashallash in the Chavin de Huantar region of Peru. 

You would be surprised how many fossils have been found this way!

The footprints are trace fossils from a big fellow who marched through here back in the Cretaceous. The inflated rust coloured prints were found alongside the fossil crocodile, pterosaurs, primitive tortoise and fish.

Antamina Mining and the Asociacion Ancash have provided funding to turn this remarkable find into an educational exhibit with a research team led by palaeontologist Carlos Vildoso. 

Vildoso along with palaeontologist Patricia Sciammaro (the two are married) founded the Instituto Peruano de Estudios en Paleovertebrados (IPEP) is a non-profit, non-government institution. Their centre focuses on vertebrate palaeontology. Over the years they have built an enviable database of significant Peruvian fossil sites and publish Contribuciones Paleontológicas, a quarterly journal devoted to vertebrate palaeontology. Chévere!

BOWRON LAKE CIRCUIT: ART OF THE PORTAGE

A cool morning breeze keeps the mosquitoes down as we pack our kayaks and gear for today’s paddling journey. 

It is day four of our holiday, with two days driving up from Vancouver to Cache Creek, past the Eocene insect and plant site at McAbee, the well-bedded Permian limestone near Marble Canyon and onto Bowron Provincial Park, a geologic gem near the gold rush town of Barkerville. 

The initial draw for me, given that collecting in a provincial park is forbidden and all collecting close at hand outside the park appears to amount to a handful of crushed crinoid bits and a few conodonts, was the gorgeous natural scenery and a broad range of species extant. 

It was also the proposition of padding the Bowron Canoe Circuit, a 149,207-hectare geologic wonderland, where a fortuitous combination of plate tectonics and glacial erosion have carved an unusual 116-kilometre near-continuous rectangular circuit of lakes, streams and rivers bound on all sides by snowcapped mountains. 

From all descriptions, something like heaven. 

The east and south sides of the route are bound by the imposing white peaks of the Cariboo Mountains, the northern boundary of the Interior wet belt, rising up across the Rocky Mountain Trench, and the Isaac Formation, the oldest of seven formations that make up the Cariboo Group (Struik, 1988). 

Some 270 million-plus years ago, had one wanted to buy waterfront property in what is now British Columbia, you’d be looking somewhere between Prince George and the Alberta border. The rest of the province had yet to arrive but would be made up of over twenty major terranes from around the Pacific. 

The rock that would eventually become the Cariboo Mountains and form the lakes and valleys of Bowron was far out in the Pacific Ocean, down near the equator. 

With tectonic shifting, these rocks drifted north-eastward, riding their continental plate, until they collided with and joined the Cordillera in what is now British Columbia. Continued pressure and volcanic activity helped create the tremendous slopes of the Cariboo Range we see today with repeated bouts of glaciation during the Pleistocene carving their final shape. 

We brace our way into a headwind along the east side of the fjord-like Isaac Lake. Paddling in time to the wind, I soak up the view of this vast, deep green, ocean-like expanse that runs L-shape for nearly 38 kilometres, forming nearly half of the total circuit. 

The rock we paddle past is primarily calcareous phyllite, limestone and quartzite, typical of the type locality for this group and considered upper Proterozoic (Young, 1969), the time in our geologic history between the first algae and the first multicellular animals.

It is striking how much this lake fits exactly how you might picture pristine wilderness paddling in your mind’s eye. No powerboats, no city hum, just pure silence, broken only by the sound of my paddle pulling through the water and the occasional burst of glee from one of the park’s many songbirds. 

We have chosen kayaks over the more-popular canoes for this journey, as I got to experience my first taste of the handling capabilities of a canoe last year in Valhalla Provincial Park. The raised sides acted like sails and kept us off course in all but the lightest conditions. 

This year, Philip Torrens, Leanne Sylvest, and I were making our trek in low profile, Kevlar style. 

One single & one double kayak would be our faithful companions and mode of transport. They would also be briefly conscripted into service as a bear shield later in the trip. Versatile those kayaks. 

The area is home to a variety of plant life. Large sections of the forest floor are carpeted in the green and white of dogwood, a prolific ground cover we are lucky enough to see in full bloom. Moss, mushrooms and small wild grown on every available surface. 

Yellow Lilies line pathways and float in the cold, clear lake water. Somewhere I read a suggestion to bring a bathing suit to the park, but at the moment, I cannot imagine lowering anything more than my paddle into these icy waters. To reach the west side of the paddling route, we must first face several kilometres portaging muddy trails to meet up with the Isaac River and then paddle rapids to grade two. 

At the launch site, we meet up with two fellow kayakers, Adele and Mary of Victoria, and take advantage of their preceding us to watch the path they choose through the rapids. It has been raining in the area for forty plus days, so the water they run is high and fast. Hot on their heels, our short, thrilling ride along the Isaac River, is a flurry of paddle spray and playing around amid all the stumps, silt and conglomerate. 

The accommodation gods smile kindly on us as we are pushed out from Isaac River and settle into McLeary Lake. An old trapper cabin built by local Freddie Becker back in the 1930s, sits vacant and inviting, providing a welcome place to hang our hats and dry out. 

From here we can see several moose, large, lumbering, peaceful animals, the largest members of the deer family, feeding on the grass-like sedge on the far shore. 

The next morning, we paddle leisurely down the slower, silt-laden Cariboo River, avoiding the occasional deadhead, and make our way into the milky, glacier-fed Lanezi Lake. Like most mountainous areas, Bowron makes its own weather system and it appears you get everything in a 24-hour period. 

In fact, whatever weather you are enjoying seems to change 40 minutes later; good for rain, bad for sun. Wisps of cloud that seemed light and airy only hours early have become dark. Careful to hug the shore, we are ready for a quick escape from lightning as thundershowers break. 

Paddling in the rain, I notice bits of mica in the water, playing in the light and the rock change here to greywacke, argillite, phyllite and schist. Past Lanezi, we continue onto Sandy Lake, where old-growth cedars line the south-facing slopes to our left and grey limestone, shale and dolostone line the shore. Mottled in with the rock, we sneak up on very convincing stumps posing as large mammals. 

Picking up the Cariboo River again, we follow it as it flows into Babcock Lake, an area edged with Lower Cambrian limestone, shale and argillite. At the time these rocks were laid down, the Earth was seeing our earliest relatives, the first chordates entering the geologic scene. 

Mamma Moose, Baby Moose... Grizzly!

As we reach the end of Babcock Lake and prepare for our next portage I get out my camera to take advantage of the angle of the sun and the eroded rounded hilltops of the Quesnel Highlands that stand as a backdrop.

Leanne remarks that she can see a moose a little ways off and that it appeared to be heading our way. 

Yes, heading our way quickly with her calf in tow. I lift my lens to immortalize the moment and we three realized they were headed our way in double time because they were being chased by a grizzly bear — at top speed. 

A full-grown moose can run up to fifty-five kilometres per hour, more or less neck and neck with the speed of a Grizzly. They are also strong swimmers. Had she been alone, Mamma moose would likely have tried to outswim the bear. 

From where we stand we can see the water turned to white foam at their feet as they fly towards us. 

We freeze bear spray in hand. 

In seconds the three were upon us. Mamma moose, using home-field advantage, runs straight for us and just reaching our boats, turned 90 degrees, bolting for the woods, baby moose fast on her heels. 

The Grizzly, caught up in the froth of running and thrill of the kill, doesn’t notice the deke, hits the brakes at the boats and stands up, confused. Her eyes give her away. 

This was not what she had planned and the whole moose-suddenly-transformed-into-human thing is giving her pause. Her head tilts back as she gets a good smell of us. 

Suddenly, a crack in the woods catches her attention. Her head snaps around and she drops back on all fours, beginning her chase anew. Somewhere there is a terrified mother moose and calf hoping the distance gained is enough to keep them from being lunch. Both moose got away with the unwitting distraction we provided. 

The Lakes are at an elevation of over 900 m (3000 ft) and both grizzly and black bear sightings are common. Both bear families descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage having just met one of the larger descendants.

While we had grumbled only hours earlier about how tired we were feeling, we now feel quite motivated and do the next two portages and lakes in good time. Aside from the gripping fear that another bear encounter is imminent, we enjoy the park-like setting, careful to scan the stands of birch trees for dark shapes now posing as stumps. Fortunately, the only wildlife we see are a few wily chipmunks, various reticent warblers and some equally shy spruce grouse. 

The wind favours us now as we paddle Skoi and Spectacle Lake, even giving us a chance to use the sails we’ve rigged to add an extra knot of oomph to our efforts. Reaching the golden land of safety-in-numbers, we leap from our kayaks, happy to see the smiling faces of Mary and Adele. Making it here is doubly thrilling because it means I’m sleeping indoors tonight and I can tell the bear story with adrenaline still pumping through my veins. Tonight is all about camaraderie and the warmth of a campfire. 

Gobbling down Philip’s famous pizza, Leanne impresses everyone further by telling of his adventures in the arctic and surviving a polar bear attack. This is our first starlit night without rain, a luxury everyone comments on, but quietly, not wanting to jinx it. We share a good laugh at the expense of the local common loons — both Homeo sapien sapien and Gavia immer. 

Common Loon / Gavia immer

The marshy areas of the circuit provide a wonderful habitat for the regions many birds including a host of sleek, almost regal black and white common loons. 

Their cool demeanour by day is reduced to surprisingly loud, maniacal hoots and yelps with undignified flapping and flailing by night. 

It seems hardly possible that these awful noises could be coming from the same birds and that this has been going for nearly 65 million years, since the end of the age of dinosaurs, as loons are one of the oldest bird families in the fossil record. 

A guitar is pulled out to liven the quiet night while small offerings, sacred and scare this late in our journey, are passed around. Tonight is a celebration that we have all, both separately and together, made our way around this immense mountain-edged circuit.

LOVE THE WILD / MOOSE: TLAWAL'S

This lovely big fella is a Moose. He is taller than most everyone you know and weighs more than your car.

You may encounter them lumbering solo along the edge of rivers and lakes, taking a refreshing swim or happily snacking on short grasses, water plants, woody shrubs and pinecones. 

You can often see them in Canada and some of the northern regions of the USA going about their business of eating and swimming. The males are called bulls and make quite a racket during mating season, also known as the Rut, using their bugle-like calls to attract a mate.

These impressive mammals are the largest living member of the deer family (Cervidae) and boast the largest set of antlers.  

The Moose you see here is a bull, a male of the species with his telltale antlers. Their impressive headgear can grow up to six feet and are used in displays of posturing, fighting or self-defence with other bulls — generally regarding a lady-moose or cow. 

Females do not have antlers but certainly, notice them. Once a mate is chosen, the new parents will produce one or two babies or calves. Fully grown, their new young will one day be able to run 55 km per hour and have excellent hearing and sense of smell. Their vision is not that good but their other senses make up for it.  

The scientific or binomial name for Moose is Alces alces (Linnaeus, 1758). The word moose is borrowed from Algonquian. 

In Narragansett, moose are called moos and in Eastern Abenaki, this large mammal is called mos. Both are likely derived from moosu, meaning he strips off. The Proto-Algonquian form was mo·swa.

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, moose are known as t̕ła̱wa̱l's — and their large crown of antler are known as wa̱t'łax̱. 

I had a close encounter on the Bowron Lake Circuit with a mamma moose, her new calf and a fully grown Grizzly chasing them. I can share that both mother and calf outran the bear. I will share that story in tomorrow's post along with the single photo I captured during their flight.

Moose are ungulates, mammals with hooves. The first ungulates appear in the fossil record about 50 million years ago. The lineage split, evolving into two groups: those with an even number of toes (Artiodactyls) and those with an uneven number of toes (Perissodactyls). 

We see the first proto-deer about 35 million years ago. These are the proto-deer like Syndyoceras who shared features with deer, horses, giraffes and antelopes. 

They had bony skull outgrowths similar to antlers and were found in North America during the Miocene, some 35 million years ago. Ten million years later, we see the first animals you and I would recognize as deer. 

Moose first appear in the fossil record during the Upper Pleistocene, a time of global glaciation.

Today, as then, their greatest threats are carnivores. Wolves, bears, cougars and humans enjoy their protein-rich meat. Humans have a curious fascination with cutting off their heads and mounting them on the wall. I get the feeding the family thing but the head mounting fetish is peculiar. We kill another 10,000 plus of their number each year with our vehicles globally. All in all, we are not all that good to this plant-loving species. 

For all that, Moose are gentle creatures if unprovoked. They sometimes ramble into town or buildings if they lose their way. 

We find them enjoying the water from garden sprinklers, randomly making their way into homes, barns and classrooms in Canada — and likely elsewhere. It is worth doing a Google search of their antics to see all that these massive mammals get up to. 

They are smart enough to know that living in the woods in hunting season can go poorly, so Moose will gather in downtown Banff and Lake Louise, hiding in plain sight to avoid becoming someone's trophy.

Across Canada today, we live alongside 500,000 to 1,000,000 of their number. Another 200,000 or so live south of us in the northern United States. Across Europe and Asia are another million-plus of their relatives.

ANCIENT WONDER OF THE ARBOREAL WORLD

Autumn is a wonderful time to explore Vancouver. It is a riot of yellow, orange and green. The fallen debris you crunch through send up wafts of earthy smells that whisper of decomposition, the journey from leaf to soil.

It is a wonderful time to be out and about. I do love the mountain trails but must confess to loving our cultivated gardens for their colour and variety. 

We have some lovely native plants and trees and more than a few exotics at Vancouver's arboreal trifecta — Van Dusen, Queen E Park and UBC Botanical Gardens. One of those exotics, at least exotic to me, is the lovely conifer you see here is Metasequoia glyptostroboides — the dawn redwood. 

Of this long lineage, this is the sole surviving species in the genus Metasequoia and one of three species of conifers known as redwoods. Metasequoia are the smaller cousins of the mighty Giant Sequoia, the most massive trees on Earth. 

As a group, the redwoods are impressive trees and very long-lived. The President, an ancient Giant Sequoia, Sequoiadendron giganteum, and granddaddy to them all has lived for more than 3,200 years. While this tree is named The President, a worthy name, it doesn't really cover the magnitude of this giant by half.   

This tree was a wee seedling making its way in the soils of the Sierra Nevada mountains of California before we invented writing. It had reached full height before any of the Seven Wonders of the Ancient World, those remarkable constructions of classical antiquity, were even an inkling of our budding human achievements. And it has outlasted them all save the Great Pyramid of Giza, the oldest and last of those seven still standing, though the tree has faired better. Giza still stands but the majority of the limestone façade is long gone.

Aside from their good looks (which can really only get you so far), they are resistant to fire and insects through a combined effort of bark over a foot thick, a high tannin content and minimal resin, a genius of evolutionary design. 

While individual Metasequoia live a long time, as a genus they have lived far longer. 

Like Phoenix from the Ashes, the Cretaceous (K-Pg) extinction event that wiped out the dinosaurs, ammonites and more than seventy-five percent of all species on the planet was their curtain call. The void left by that devastation saw the birth of this genus — and they have not changed all that much in the 65 million years since. Modern Metasequoia glyptostroboides looks pretty much identical to their late Cretaceous brethren.

Dawn Redwood Cones with scales paired in opposite rows

They are remarkably similar to and sometimes mistaken for Sequoia at first glance but are easily distinguishable if you look at their size (an obvious visual in a mature tree) or to their needles and cones in younger specimens. 

Metasequoia has paired needles that attach opposite to each other on the compound stem. Sequoia needles are offset and attached alternately. Think of the pattern as jumping versus walking with your two feet moving forward parallel to one another. 

Metasequoia needles are paired as if you were jumping forward, one print beside the other, while Sequoia needles have the one-in-front-of-the-other pattern of walking.

The seed-bearing cones of Metasequoia have a stalk at their base and the scales are arranged in paired opposite rows which you can see quite well in the visual above. Coast redwood cone scales are arranged in a spiral and lack a stalk at their base.

Although the least tall of the redwoods, it grows to an impressive sixty meters (200 feet) in height. It is sometimes called Shui-sa, or water fir by those who live in the secluded mountainous region of China where it was rediscovered.

Fossil Metasequoia, McAbee Fossil Beds

Metasequoia fossils are known from many areas in the Northern Hemisphere and were one of my first fossil finds as a teenager. 

And folk love naming them. More than twenty fossil species have been named over time —  some even identified as the genus Sequoia in error — but for all their collective efforts to beef up this genus there are just three species: Metasequoia foxii, Metasequoia milleri, and Metasequoia occidentalis.

During the Paleocene and Eocene, extensive forests of Metasequoia thrived as far north as Strathcona Fiord on Ellesmere Island and sites on Axel Heiberg Island in Canada's far north around 80° N latitude.

We find lovely examples of Metasequoia occidentalis in the Eocene outcrops at McAbee near Cache Creek, British Columbia, Canada. I shared a photo here of one of those specimens. Once this piece dries out a bit, I will take a dental pick to it to reveal some of the teaser fossils peeking out.

The McAbee Fossil Beds are known for their incredible abundance, diversity and quality of fossils including lovely plant, insect and fish species that lived in an old lake bed setting. While the Metasequoia and other fossils found here are 52-53 million years old, the genus is much older. It is quite remarkable that both their fossil and extant lineage were discovered in just a few years of one another. 

Metasequoia was first described as a new genus from a fossil specimen found in 1939 and published by Japanese paleobotanist Shigeru Miki in 1941. Remarkably, the living version of this new genus was discovered later that same year. 

Professor Zhan Wang, an official from the Bureau of Forest Research was recovering from malaria at an old school chum's home in central China. His friend told him of a stand of trees discovered in the winter of 1941 by Chinese botanist Toh Gan (干铎). The trees were not far away from where they were staying and Gan's winter visit meant he did not collect any specimen as the trees had lost their leaves. 

The locals called the trees Shui-sa, or water fir. As trees go, they were reportedly quite impressive with some growing as much as sixty feet tall. Wang was excited by the possibility of finding a new species and asked his friend to describe the trees and their needles in detail. Emboldened by the tale, Wang set off through the remote mountains to search for his mysterious trees and found them deep in the heart of  Modaoxi (磨刀溪; now renamed Moudao (谋道), in Lichuan County, in the central China province of Hubei. He found the trees and was able to collect living specimens but initially thought they were from Glyptostrobus pensilis (水松). 

A few years later, Wang showed the trees to botanist Wan-Chun Cheng and learned that these were not the leaves of s Glyptostrobus pensilis (水松 ) but belonged to a new species. 

While the find was exciting, it was overshadowed by China's ongoing conflict with the Japanese that was continuing to escalate. With war at hand, Wang's research funding and science focus needed to be set aside for another two years as he fled the bombing of Beijing. 

When you live in a world without war on home soil it is easy to forget the realities for those who grew up in it. 

Zhan Wang and his family lived to witness the 1931 invasion of Manchuria, then the 1937 clash between Chinese and Japanese troops at the Marco Polo Bridge, just outside Beijing. 

That clash sparked an all-out war that would grow in ferocity to become World War II. 

Within a year, the Chinese military situation was dire. Most of eastern China lay in Japanese hands: Shanghai, Nanjing, Beijing, Wuhan. As the Japanese advanced, they left a devastated population in their path where atrocity after atrocity was the norm. Many outside observers assumed that China could not hold out, and the most likely scenario was a Japanese victory over China.

Yet the Chinese hung on, and after the horrors of Pearl Harbor, the war became genuinely global. The western Allies and China were now united in their war against Japan, a conflict that would finally end on September 2, 1945, after Allied naval forces blockaded Japan and subjected the island nation to intensive bombing, including the utter devastation that was the Enola Gay's atomic payload over Hiroshima. 

With World War II behind them, the Chinese researchers were able to re-focus their energies on the sciences. Sadly, Wang was not able to join them. Instead, two of his colleagues, Wan Chun Cheng and Hu Hsen Hsu, the director of Fan Memorial Institute of Biology would continue the work. Wan-Chun Cheng sent specimens to Hu Hsen Hsu and upon examination realised they were the living version of the trees Miki had published upon in 1941. 

Hu and Cheng published a paper describing a new living species of Metasequoia in May 1948 in the Bulletin of Fan Memorial Institute of Biology.

That same year, Arnold Arboretum of Harvard University sent an expedition to collect seeds and, soon after, seedling trees were distributed to various universities and arboreta worldwide. 

Today, Metasequoia grow around the globe. When I see them, I think of Wang and all he went through. He survived the conflict and went on to teach other bright, young minds about the bountiful flora in China. I think of Wan Chun Cheng collaborating with Hu Hsen Hsu in a time of war and of Hu keeping up to date on scientific research, even published works from colleagues from countries with whom his country was at war. Deep in my belly, I ache for the huge cost to science, research and all the species impacted on the planet from our human conflicts. Each year in April, I plant more Metasequoia to celebrate Earth Day and all that means for every living thing on this big blue orb.

DANCING ATOMS: AURORA BOREALIS

If you live in the northern hemisphere, you stand a very good chance of seeing the aurora borealis this evening. We got a spectacular showing last night. Those glorious dancing lights will be most visible from 11PM-4AM PST with their brilliance tapering off over the next few days.

Even with a fair bit of light pollution, you can see the colours quite clearly. Tonight's best showing is in the late afternoon to early evening. I am excited to see what we will see. 

The Earth has a magnetic field with north and south poles. The lights we see are the result of severe storms that push protons past their normal threshold around these two polar regions.  

The magnetic field of the Earth is surrounded by the magnetosphere which keeps most of the particles from the Sun from hitting the Earth. Some of these particles from the solar wind enter the atmosphere at one million miles per hour. The auroras occur when highly charged electrons from the solar wind interact with elements in the Earth's atmosphere and become trapped in the Earth's magnetic field. 

We see them as an undulating visual field of red, yellow, green, blue and purple dancing high in the Earth's atmosphere — about 100 to 400 kilometres above us. The green is the result of millions of oxygen atoms dancing like gleeful children as they decay back to their original state. 

The red is also caused by oxygen atoms but because those atoms are higher up in the atmosphere we register much of their vivid colour as green or reddish-green because of our poorly developed eyesight and lower red light emissions. 

Nitrogen atoms are a bit more standoffish. They get in on the action but only if the storm winds are very strong as it takes quite a hard hit to excite them. 

If you have been in the quiet northern regions for an aurora storm, you can hear their clapping sounds. On cold, clear nights, with light wind, a temperature inversion can form. This happens when a layer of relatively warm air creates a blanket over a shallow layer of cold air. 

Solar winds excite the atoms in the inversion layer, with opposite charges building up in the colder layer near the ground. When the aurora increases in intensity, geomagnetic disturbances travel down through the atmosphere causing the two layers to spark. 

We hear that electric discharge or spark as a click, click, click, clapping or banging sound. 

All science aside, what we see from these rare energetic interactions is one of the most beautiful of all-natural phenomena — Earth's polar lights, the aurora borealis in the north and the aurora australis, near the south pole. Vancouver had a wonderful surprise viewing a few weeks ago and tonight looks like it will provide another. 

The aurora borealis is best viewed in the north, of course, and many of my relatives have a bird's-eye view. To the Tlingit First Nation of Alaska, the aurora is Gis'óok. In Norway, the aurora is Nordlys — and by any name, spectacular.

BITS OF HISTORY: CANADA / A GEOLOGIC GEM IN THE MAKING

Canada's early history, like all nations, is written in her rock. The ground we walk upon today on Turtle Island includes some of the oldest rocks on the planet. 

While you and I were not there to witness it, our planet formed a little over 4.5 billion years ago when a massive collection of dust and gas, the leavings of our newly formed Sun, swirled and spun, gathering into a molten liquid sphere.    

Half a billion years later, our planet began to cool, the molten crust hardening into the first of our tectonic plates. 

These giant puzzle pieces moved together and separated over vast expanses of time to form, pull apart and reform into a series of supercontinents divided by ancient oceans. 

As you explore Canada, you can see evidence of our planet's early history. Canadian geology spans four billion years of Earth history. Four. Billion. Years. Yes, that is quite a bit to process for our young minds. The oldest rocks are preserved in the stable Archean crustal blocks of which the largest include the Superior, Slave, Hearne and North Atlantic cratons. These blocks are also the repository for much of Canada’s gold, copper, iron, zinc and diamonds. 

The Archean cratons were stitched together by Paleoproterozoic mountain belts that resulted in supercontinent Nuna and host important deposits of nickel, copper and platinum group elements. The Mesoproterozoic is dominated by the Grenville orogen another old mountain belt that extends from central Ontario to Labrador. Sedimentary basins of these ages are prominently represented on the opposite (northwest) margin of the Canadian Shield in the Northwest Territories.

The modern geometry of Canada has its origins in the breakup of the supercontinent Rodinia. Neoproterozoic rifting led to new ocean basins and to trailing continental margins now prominently represented in the Appalachians, western Cordillera and Arctic Islands. 

Plate tectonics in the lower Paleozoic introduced oceanic crust to the rock record of Newfoundland and southern Quebec and accretion of exotic crustal fragments in Atlantic Canada and the High Arctic. 

Similarly, warm ocean conditions in Cambrian to Devonian time produced widespread carbonate platforms over the St. Lawrence Lowlands, the Western Interior, Mackenzie Corridor, Hudson Bay and the southern Arctic.

Events of the Mesozoic are prominently represented by the accretion of continental fragments to the western margin of North America — the landmass referred to as Turtle Island by many First Nation, . This remained a tectonically active region into Eocene time and during this interval produced important deposits of copper, lead, zinc, molybdenum, gold, silver, tungsten and other commodities. 

The depositional record of these events is partly recorded in the Western Canada Sedimentary Basin which is a prolific producer of oil, gas and coal. Hydrocarbons are also an important part of the sediment accumulation story since the Jurassic off the East Coast. Likewise, the tectonically active Cretaceous to Eocene record in the Arctic Islands relates to the origin of the Arctic Ocean and the independent plate motions of Greenland.

About 80 million years ago, North America separated from Europe, Australia began to rift away from Antarctica, and India broke away from Madagascar. 

Our northern and southern edges abut the United States. Interestingly, at their nearest points, Alaska and Russia are separated by only 4 kilometres (2.5 miles).

AUTUMN MUSHROOM BOUNTY

Dappled light caresses this mature Fly Agaric, Amanita muscaria, mushroom caught unaware beneath a bit of camouflaging foliage. 

These iconic toadstool denizens of our Oak and coniferous forests are both fetching and poisonous. 

You can eat them as hazardous haute cuisine with a bit of preparation — parboil them twice, each time with fresh water then nibble carefully before you go all in — but they are arguably better utilized as a photographic subject.

Folk will do what they do, but I place these colourful mushrooms firmly in the do not eat category. If you break them apart and put them in any type of liquid that attracts flies, the flies will die from ibotenic acid poisoning — hence the mushroom's common name, Fly Agaric. 

In Latin, they are Amanita muscaria, with musca meaning a fly. Albertus Magnus (c. 1200 – 15 November 1280), known as Saint Albert the Great or Albert of Cologne, was a German Catholic Dominican friar, philosopher, scientist, and bishop and arguably the greatest German philosopher and theologian of the Middle Ages. 

Magnus was the first to record it in his work De vegetabilibus sometime before 1256, commenting "vocatur fungus muscarum, eo quod in lacte pulverizatus interficit muscas," which translates to: "it is called the fly mushroom because it is powdered in milk to kill flies."

ETHELDRED'S HOPLITES

Hoplites (Hoplites) bennettiana (Sowerby, 1826)

A beautiful example of the ammonite, Hoplites (Hoplites) bennettiana (Sowerby, 1826), from Early Albian localities in the Carrière de Courcelles Villemoyenne, Région de Troyes, near Champagne in northeastern France.

The species name is a homage to Etheldred Benett, an early English geologist often credited with being the first female geologist — a fossil collector par excellence.

She was also credited with being a man  —  the Natural History Society of Moscow awarding her membership as Master Etheldredus Benett in 1836. The confusion over her name — it did sound masculine — came again with the bestowing of a Doctorate of Civil Law from Tsar Nicholas I.

The Tsar had read Sowerby's Mineral Conchology, a major fossil reference work that contained the second-highest number of contributed fossils of the day, many of the best quality available at the time. Forty-one of those specimens were credited to Benett. Between her name and this wonderous contribution to a growing science, the Russian Tsar awarded the Doctorate to what he believed was a young male scientist on the rise. He believed in education, founding Kyiv University in 1834, just not for women. He was an autocratic military man frozen in time — the thought that this work could have been done by a female unthinkable. Doubly charming is that the honour from the University of St Petersburg was granted at a time when women were not allowed to attend St. Pete's or any higher institutions. That privilege arrived in 1878, twenty years after Nicholas I's death.

Benett took these honours (and social blunders) with grace. She devoted her life to collecting and studying fossils from the southwest of England, amassing an impressive personal collection she openly shared with geologist friends, colleagues and visitors to her home. Her speciality was fossils from the Middle Cretaceous, Upper Greensand in the Vale of Wardour — a valley in the county of Wiltshire near the River Nadder.

Etheldred Benett was born on 22 July 1775 at Pyt House, Tisbury, Wiltshire, the eldest daughter of the local squire Thomas Benett.

Etheldred's interest was cultivated by the botanist Aylmer Bourke Lambert (1761-1842), a founding member of the Linnean Society. Benett's brother had married Lucy Lambert, Aylmer's half-sister. Aylmer was a Fellow of the Royal Society and the Society of the Arts. He was also an avid fossil collector and member of the Geological Society of London. The two met and got on famously.

Aylmer kindled an interest in natural history in both of Benett's daughters. Etheldred had a great fondness for geology, stratigraphy and all things paleo, whilst her sister concentrated on botany. Etheldred had a distinct advantage over her near contemporary, the working-class Mary Anning (1799-1847), in that Benett was a woman of independent wealth who never married — and didn't need to — who could pursue the acquisition and study of fossils for her own interest.

While Anning was the marine reptile darling of the age, she was also greatly hindered by her finances. "She sells, seashells by the seashore..." while chanted in a playful spirit today, was not meant kindly at the time.

Aylmer's encouragement emboldened Etheldred to go into the field to collect for herself — and collect she did. Profusely.

Benett’s contribution to the early history of Wiltshire geology is significant. She corresponded extensively with the coterie of gentlemen scientists of the day —  Gideon Mantell, William Buckland, James Sowerby, George Bellas Greenough and, Samuel Woodward. She also consorted with the lay folk and had an ongoing correspondence with William Smith, whose stratigraphy work had made a favourable impression on her brother-in-law, Aylmer.

Her collections and collaboration with geologists of the day were instrumental in helping to form the field of geology as a science. One colleague and friend, Gideon Mantell, British physician, geologist and palaeontologist, who discovered four of the five genera of dinosaurs and Iguanadon, was so inspired by Benett's work he named this Cretaceous ammonite after her — Hoplites bennettiana.

Benett's fossil assemblage was a valuable resource for her contemporaries and remains so today. It contains thousands of Jurassic and Cretaceous fossil specimens from the Wiltshire area and the Dorset Coast, including a myriad of first recorded finds. The scientific name of every taxon is usually based on one particular specimen, or in some cases multiple specimens. Many of the specimens she collected serve as the Type Specimen for new species.

Fossil Sponge, Polypothecia quadriloba, Warminster, Wiltshire

Her particular interest was the collection and study of fossil sponges. Alcyonia caught her eye early on. She collected and recorded her findings with the hope that one of her colleagues might share her enthusiasm and publish her work as a contribution to their own. Alas, no one took up the helm — those interested were busy with other pursuits (or passed away) and others were less than enthusiastic or never seemed to get around to it.

To ensure the knowledge was shared in a timely fashion, she finally wrote them up and published them herself. You can read her findings in her publication, ‘A Catalogue of Organic Remains of the County of Wiltshire’ (1831), where she shares observations on the fossil sponge specimens and other invert goodies from the outcrops west of town.

She shared her ideas freely and donated many specimens to local museums. It was through her exchange of observations, new ideas and open sharing of fossils with Gideon Mantell and others that we gained a clearer understanding of the Lower Cretaceous sedimentary rocks of Southern England.

In many ways, Mantell was drawn to Benett as his ideas went against majority opinion. At a time when marine reptiles were dominating scientific discoveries and discussions, he pushed the view that dinosaurs were terrestrial, not amphibious, and sometimes bipedal. Mantell's life's work established the now-familiar idea that the Age of Reptiles preceded the Age of Mammals. Mantell kept a journal from 1819-1852, that remained unpublished until 1940 when E. Cecil Curwen published an abridged version. (Oxford University Press 1940). John A. Cooper, Royal Pavilion and Museums, Brighton and Hove, published the work in its entirety in 2010.

I was elated to get a copy, both to untangle the history of the time and to better learn about the relationship between Mantell and Benett. So much of our geologic past has been revealed since Mantell's first entry two hundred years ago. The first encounter we share with the two of them is a short note from March 8, 1819. "This morning I received a letter from Miss Bennett of Norton House near Warminster Wilts, informing me of her having sent a packet of fossils for me, to the Waggon Office..." The diary records his life and the social interactions of the small connected community of the scientific social elite — pure delight.

Though a woman in a newly evolving field, her work, dedication and ideas were recognized and appreciated by her colleagues. Gideon Mantell described her as, "a lady of great talent and indefatigable research," whilst the Sowerbys noted her, "labours in the pursuit of geological information have been as useful as they have been incessant."

Benett produced the first measured sections of the Upper Chicksgrove quarry near Tisbury in 1819, published and shared with local colleagues as, "the measure of different beds of stone in Chicksgrove Quarry in the Parish of Tisbury.” The stratigraphic section was later published by naturalist James Sowerby without her knowledge. Her research contradicted many of Sowerby’s conclusions.

She wrote and privately published a monograph in 1831, containing many of her drawings and sketches of molluscs and sponges. Her work included sketches of fossil Alcyonia (1816) from the Green Sand Formation at Warminster Common and the immediate vicinity of Warminster in Wiltshire.

Echinoids and Bivalves. Collection of Etheldred Benett (1775-1845)

The Society holds two copies, one was given to George Bellas Greenough, and another copy was given to her friend Gideon Mantell. This work established her as a true, pioneering biostratigrapher following but not always agreeing with the work of William Smith.

If you'd like to read a lovely tale on William's work, check out the Map that Changed the World: William Smith and the Birth of Modern Geology by Simon Winchester. It narrates the intellectual context of the time, the development of Smith's ideas and how they contributed to the theory of evolution and more generally to a dawning realization of the true age of the earth.

The book describes the social, economic or industrial context for Smith's insights and work, such as the importance of coal mining and the transport of coal by means of canals, both of which were a stimulus to the study of geology and the means whereby Smith supported his research. Benett debated many of the ideas Smith put forward. She was luckier than Smith financially, coming from a wealthy family, a financial perk that allowed her the freedom to add fossils to her curiosity cabinet at will.

Most of her impressive collection was assumed lost in the early 20th century. It was later found and purchased by an American, Thomas Bellerby Wilson, who donated it to the Academy of Natural Sciences of Philadelphia. Bits of her collection made their way into British museums. Leeds City Museum, the British Museum in London, Bristol Museum and the University of St. Petersburg all house her specimens. These collections contain many of the first fossils found of their kind — some with the soft tissues preserved. When Benett died in 1845, it was Mantell who penned her obituary for the London Geological Journal.

Etheldred Benett (1776-1845)

In 1989, almost a hundred and fifty years after her death, a review of her collection had Arthur Bogen and Hugh Torrens remark that her work has significantly impacted our modern understanding of Porifera, Coelenterata, Echinodermata, and the molluscan classes, Cephalopoda, Gastropoda, and Bivalvia. A worthy legacy, indeed.

Her renown lives on through her collections, her collaborations and through the beautiful 110 million-year-old ammonite you see here, Hoplites bennettiana. The lovely example you see here is in the collection of the deeply awesome Christophe Marot.

GOLDEN DALMANITES

Dalmanites is a genus of trilobite in the order Phacopida. These extinct arthropods lived from the Late Ordovician to Middle Devonian. 

Trilobites of this genus have slightly convex exoskeletons with an average length of 4–7 cm. The cephalon is semicircular or parabolic.

This fellow has lost his distinctive tail spine that is the signature characteristic of this genus. 

Trilobites — in all their many wonderful forms — lived in our ancient oceans for more than 270 million years. The last of their lineage went extinct at the end of the Permian, 252 million years ago.

FOSSIL HUNTRESS PODCAST

The first episode of the Fossil Huntress Podcast was October 12, 2020. It started with a bang of 47 episodes in the first season. 

Since then, I have slowed down a bit to deliver 85 episodes over the course of this past year. 

The podcast has gained a broad audience globally with over 10,000 listens from 65 countries. It attracts those who love the realm of palaeontology with its sexy ammonites, trilobites and dinosaurs, but also a general science audience of those who love the natural world. 

The podcast has changed the way I interact with those who read my work and made me a better storyteller — though, in truth, I am still learning. 

With a large part of my listeners speaking English as their second, third or fourth language, it has made me aware of the many idioms and gambits so common in our English tongue. I have added a translate button to the ARCHEA blog so folk can read it in their language of choice as much of what I share on the podcast is also shared via the blog — only with pictures instead of descriptions.  

HOLLARDOPS: LE MAÎTRE

Hollardops sp. Devonian Trilobite

Hollardops is a genus of trilobite in the order Phacopida that lived during the Eifelian of the Middle Devonian. It was described by Le Maître in 1952 under type species Metacanthina mesocristata. 

The genus underwent reclassification in 1997 and emerged as Hollardops. We find this extinct arthropod in present-day Morocco. They share similarities with Greenops of New York and Canada but are generally larger than most Greenops species.

Hollardops have schizochroal eyes and a glabella that is slightly raised on the surface of the cephalon. Genal spines extend from the cephalon and extend to approximately the 6th thoracic segment.

Hollardops has eleven thoracic segments and also has five pairs of spines extending from the segments of the pygidium. Length ranges from approximately 3 to 9 cm.

HEROES, VILLAINS AND TYRANTS: HORNBY ISLAND HISTORY

Villains, tyrants and heroes alike are immortalized in the scientific literature as researchers don each new species a unique scientific name — and rename geographic sites with a settlers' mindset. 

If you pick through the literature, it is a whose who of monied European explorers literally making a name for themselves, sometimes at great cost to their rivals. 

This truth plays out on British Columbia's West Coast and gulf islands and on Hornby Island, in particular. 

The beautiful island of Hornby is in the traditional territory of the Pentlatch or K’ómoks First Nation, who call it Ja-dai-aich, which means the outer island — a reference to Hornby being on the outside of Denman Island off the east coast of Vancouver Island. 

The island is a mix of beach and meadow, forest and stream. While I often walk the lower beachfront, this island boasts a lovely and very walkable mixed forest that covers its higher ground. 

If you explore here, off the beaten path, you will see a mix of large conifers — Western Hemlock, Grand Fir and Lodgepole Pine on the island. Of these, the Western Red Cedar, Thuja plicata, is the most prized by First Nations. It is the Tree of Life that provides bountiful raw materials for creating everything from art to homes to totems and canoes. 

If you explore these forests further, you will also see wonderful examples of the smaller Pacific yew, Taxus brevifolia, a wee evergreen that holds a special place in the hearts of First Nations whose carvers use this wood for bows and paddles for canoes.

Many spectacular specimens of arbutus, Arbutus menziesii, grow along the water's edge. These lovely evergreens have a rich orange-red bark that peels away in thin sheets, leaving a greenish, silvery smooth appearance and a satiny sheen. Arbutus, the broadleaf evergreen species is the tree I most strongly associate with Hornby. Hornby has its fair share of broadleaf deciduous trees. Bigleaf maple, red alder, black cottonwood, Pacific flowering dogwood, cascara and several species of willow thrive here.

There are populations of Garry oak, Quercus garryana, with their deeply lobed leaves, on the southern end of the island and at Helliwell Provincial Park on a rocky headland at the northeast end of Hornby. 

Local First Nations fire-managed these stands of Garry oak, burning away shrubs and other woody plants so that the thick-barked oaks and nutritious starch-rich plants like great camas, Camassia leichtlinii, could thrive without any nutrient competitors. 

Only about 260 acres (1.1 km2) of undisturbed stands of older forests have been identified on Hornby. They amount to roughly 3.5% of the island's surface area. There are roughly 1,330 acres (540 ha) of older second-growth stands on the island, roughly 19% of the island.

Most of the trees you see on the island are Douglas fir, Pseudotsuga menziesii, an evergreen conifer species in the pine family. My Uncle Doug recognized this tree species because of how much the bark looks like bacon — a food he loved. The common name is a nod to the Scottish botanist, David Douglas, who collected and first reported on this large evergreen.

Captain George Vancouver's Commission to Lieutenant

Sadly for Douglas, it is Archibald Menzies, a Scottish physician, botanist, naturalist — and David's arch-rival, whose name is commemorated for science. 

He is also credited with the scientific naming of our lovely arbutus trees. 

Menzies was part of the Vancouver Expedition (1791–1795) a four-and-a-half-year voyage of exploration commanded by Captain George Vancouver of the British Royal Navy.

Their voyage was built on the work of James Cook. Cook was arguably the first ship's captain to ensure his crew remained scurvy free by implementing a practice of nutritious meals — those containing ascorbic acid also known as Vitamin C — and meticulous standards for onboard hygiene. 

Though he did much to lower the mortality rate amongst his crew, he made some terrible decisions that led to his early demise. Cook was attacked and killed in 1779 during his third exploratory voyage in the Pacific while attempting to kidnap the Island of Hawaii's monarch, Kalaniʻōpuʻu. 

During the four and a half year Vancouver Expedition voyage, the crew and officers bickered amongst themselves, circumnavigated the globe, touching down on five continents. Little did they know, for many of them it would be the last voyage they would ever take. 

The expedition returned to a Britain more interested in its ongoing war than in Pacific explorations. Vancouver was attacked by the politically well-connected Menzies for various slights, then challenged to a duel by Thomas Pitt, the 2nd Baron of Camelford. 

The fellow for whom the fair city of Vancouver is named never did complete his massive cartographical work. With health failing and nerves eroded, he lost the dual and his life. It was Peter Puget, whose name adorns Puget Sound, who completed Vancouver's — and arguably Cook's work on the mapping of our world.

And while it is now called Vancouver the city has many names as it falls within the traditional territory of three Coast Salish peoples — the Squamish (Sḵwxwú7mesh), Tsleil-waututh and Xwméthkwyiem ("Musqueam"—from masqui "an edible grass that grows in the sea"), and on the southern shores of Vancouver along the Fraser River, the Xwméthkwyiem.

If you would like to explore more of the history of eponymous naming from Linnaeus to Darwin, to Bowie himself, take a boo at a new book from Stephen B. Heard, "Charles Darwin's Barnacle and David Bowie's Spider. It is fresh off the press and chock full of historical and pop-culture icons.

• A letter to James Sykes (a Navy Agent in London) written from the ship Discovery (not the same Discovery used by Cook) while in Nootka Sound near the end of Vancouver’s exploration of the West Coast, October 2, 1794.

HORNBY ISLAND FOSSIL COLLECTING

Pachydiscus suchiaensis ID: 18-08-CP-002

Hornby is a glorious place to collect. It is family and dog friendly. You need to dress for beach collecting preferably with rubber boots, eye protection and clothing for both sun and rain. 

I like to bring a 5-gallon bucket or hard plastic bottomed backpack for my finds. Whatever you bring is going to get wet, muddy and laced with sand. 

As well as a rock hammer, I bring a 2-4 pound sledgehammer and rock pick for collecting and cracking open the concretions here. If you are lucky, when you split them you see a fossil hidden within. 

While that is not always the case, the rewards are well-worth. One such beauty from a glorious day of collecting on Hornby is the beautiful ammonite you see here.

It is nestled amongst the seaweed and modern oysters clinging to the grey shales of the Northumberland Formation is the Upper Cretaceous (Campanian) ammonite Pachydiscus suchiaensis. This is one of my favourite species and is treasured both for its beauty and the fossil site it hails from. 

This darling was found in situ in the 72 million-year-old sediments at Collishaw Point on the northwest side of Hornby Island, southwestern British Columbia.

The island is beautiful in its own right and the fossils from here often keep some of their original shell or nacre which makes them quite fetching. This fellow is found amongst gastropods, shark teeth, fossil crabs, baculites and other bivalve fossils. 

Many of the fossils found at this locality are found in concretions rolled smooth by time and tide. The concretions you find on the beach are generally round or oval in shape and are made up of hard, compacted sedimentary rock. 

These past few years, many new and wonderful specimens have been unearthed — particularly by members of the Vancouver Island Palaeontological Society (VIPS). 

Two particular finds are jaw-droppers — a Diploceras (think one-metre long paperclip, except it is a heteromorph ammonite) longer than your arm and Actinosepia gladius — internal hard body part found in many cephalopods — of a Vampyropod, a member of the proposed group Vampyropoda — equivalent to the superorder Octopodiformes — which includes vampire squid and octopus. 

Not all of these beauties come out in one piece and as well as amazing collecting skill, the VIPS boasts some of the best Fossil Preparators in British Columbia. A nod of respect to both Jason Hawley and Rick Ross in this regard. Rick is a skilled collector and found a rather nice and rare pachydiscid ammonite at Hornby this past year that I had never seen before. It has been a good year for collecting at Collishaw Point. Another notable find was the decapod, Archaeopus vancouverensis (Woodward 1896), found by Adam Melzak this past summer. If you are looking to get out and about, fossil collecting on Hornby Island is the perfect day trip or weekend getaway.

Where to View the Fossils:

The Courtenay Museum, Qualicum Museum and Pacific Museum of the Earth have delightful collections of specimens from the Upper Cretaceous of Hornby Island. This lovely heteromorph ammonite, Nostoceras hornbyense (Whiteaves, 1895) is a classic. The photo below is courtesy of John Fam, Vice-Chair of the Vancouver Paleontological Society (VIPS) on a recent visit to poke through the collections at the Pacific Museum of the Earth. 

It is a classic example of the heteromorph specimens found at Hornby. Bob Copeman found the best Nostoceras hornbyense I have ever seen from these outcrops. Lucky for you, a replica of that specimen has been made is available to be purchased from the VIPS. Always a nice addition to the collection — especially if you keep a teaching collection where specimens need to be handled by younger, rougher hands.

Nostoceras hornbyense (Whiteaves, 1895)

The main topographic feature on Hornby Island is an arcuate mountain of the resistant cliff-forming Geoffrey formation. Near Shingle Spit about half a mile from the coast is Mt. Geoffrey 920-foot peak; from there the mountain gradually drops in elevation to the southeast and to the north.  

It is 700-feet of conglomerate in a homocline striking N 20° W and dipping to the northeast at a shallow angle of about 6°. 

The apex of the arcuate mountain belt points to the southwest. The coast of Hornby is probably a rising shoreline, as indicated by the almost perpendicular cliffs along its periphery. A hundred (100) foot cliffs of Lambert shale extends from Shingle Spit to Phipps Point, while from the latter to Boulder Point, the cliffs are not as steep and are covered in many places by vegetation.

Behind the mountain and almost enclosed by it is the fertile, green Strachan Valley. On the large peninsula which extends in a southeast direction from the north of the island towards St. John’s Point, the Hornby Formation outcrops form the cliffs on the east side of Tribune Bay. The highest of these is about 200 feet. The argillaceous Lambert and Spray formations form the subdued lowlands of the island.
