GIANT GROUND SLOTH

In 1788, this magnificent specimen of a Megatherium sloth was sent to the Royal Cabinet of Natural History from the Viceroyalty of Rio de la Plata.

The megaterios were large terrestrial sloths belonging to the group, Xenarthra. These herbivores inhabited large areas of land on the American continent. Their powerful skeleton enabled them to stand on their hind legs to reach leaves high in the trees, a huge advantage given the calories needed to be consumed each day to maintain their large size.

Avocados were one of the food preferences of our dear Giant ground sloths. They ate then pooped them out, spreading the pits far and wide. The next time you enjoy avocado toast, thank this large beastie. One of his ancestors may have had a hand (or butt) in your meal.

In 1788, Bru assembled the skeleton as you see it here. It is exhibited at the Museo Nacional De Ciencias Naturales in Madrid, Spain, in its original configuration for historic value. If you look closely, you'll see it is not anatomically correct. But all good paleontology is teamwork. Based upon the drawings of Juan Bautista Bru, George Cuvier used this specimen to describe the species for the very first time.

MIDDLE TRIASSIC AMMONOID & BELEMNITE

A beautiful plate with a lovely example of the Middle Triassic ammonoid and belemnite from Fossil Hill in the Humboldt Mountains of Nevada. This locality is perhaps the most famous and important locality for the Middle Triassic (Anisian/Ladinian) of North America.

This was the site of the 1905 Expedition of the University of California’s Department of Geology in Berkeley funded by the beautiful and bold, Annie Alexander, the women to whom the UCMP owes both its collection and existence. J. P. Smith joined the expedition, though he was interested in the invertebrate fauna, not the mighty marine reptiles that helped get the project funded.

J.P. Smith published on the marine fauna in the early 1900s. They formed the basis for his monograph on North American Middle Triassic marine invertebrate fauna published in 1914.

N. J. Siberling from the US Geological Survey published on these outcrops in 1962. His work included nearly a dozen successive ammonite faunas, many of which were variants on previously described species. Evidently, his collections consisted mainly of weathered material and were made without stratigraphic control because he believed that most, if not all, of these species, were coexistent. The fossiliferous beds found here, as well as localities in north-western Nevada, were designated the 'Daonella dubia' zone. Dubious would be closer to the truth. Smith joined the 1905 Expedition of the University of California’s Department of Geology in Berkeley funded by the beautiful and bold, Annie Alexander, the women to whom the UCMP owes both its collection and existence.

AN ANCIENT MARINE LINEAGE

Life on Earth began in the oceans more than 3.5 billion years ago. That means that all of us, all of our homo sapien sapien brethren and every living thing on the planet is a  descendant of a marine organism.

Knowing that we share an ancient history with every living species is rather humbling. While we diverged early on from cats, dogs, frogs and birds, we share a history and proud lineage with all the vertebrates alive today.

I was up hunting for trilobites near Cranbrook and came across a graptolite. It looked like a wee pen mark on a bit of rock. It too is one of our relatives and one of the earliest. So how did vertebrates go from worm-like marine animals like Metaspriggina, to the modern diversity of forms?

CRETACEOUS NAUTILUS OF MEXICO

A picture-perfect Campanian nautilus, Eutrophoceras irritilansis,
who lived during the Upper Cretaceous (late Campanian) near the town of Porvenir de Jalpa (about 64 km / 40 miles west of Saltillo) in what is now southern Coahuila (formerly Coahuila de Zaragoza), northern Mexico. Collection of Jose Ventura.

FERGUSON HILL, NEVADA

Ferguson Hill contains the most complete macrofossil record spanning the Triassic-Jurassic boundary in North America. The ammonoids from the uppermost Triassic can be traced to the boundary and the earliest ammonites (Psiloceratids) can be seen right at the base of the Jurassic (Hettangian).

It was in contention for the Global Stratotype Section and Point (GSSP) defining the base of the Jurassic System, Lower Jurassic Series and Hettangian Stage. However, in 2008, the Kuhjoch (Karwendel Mountains, Northern Calcareous Alps, Tyrol, Austria) was chosen over Ferguson Hill mainly because the beds containing the oldest Psiloceras (P. spelae spelae) were better preserved and contained Hettangian microfossils.

ROCKY MOUNTAIN COUGAR

Cougars are meat-eating mammals (primarily dining on deer) who boast being the most widely distributed land mammal in the Western Hemisphere. They are impressive athletes, able to leap 18 feet or more straight upward from a sitting position.

They lead solitary lives and are excellent at avoiding humans for the most part. Cougars have a massive range that runs from the mountainous Canadian Rockies in northwestern Canada all the way down to Patagonia in South America. These cats make their dens in mountain graggs, along rocky ledges, in dense woodland areas and under uprooted trees and debris.

FOSSIL RELIC: AMIIFORMES

This well-preserved fossil fish skull is from Calamopleurus (Agassiz, 1841), an extinct genus of bony fishes related to the heavily armoured ray-finned gars.

They are fossil relics, the sole surviving species of the order Amiiformes. Although bowfins are highly evolved, they are often referred to as primitive fishes and living fossils as they retain many of the morphologic characteristics of their ancestors.

This specimen was found in Lower Cretaceous outcrops of the Santana Formation in the Araripe Basin UNESCO Global Geopark of northeastern Brazil. Collection of David Murphy

NOTOCHORDS: CHORDATES TO CALAMARI

You and I are vertebrates, we have backbones. Having a backbone or spinal column is what sets apart you, me and almost 70,000 species on this big blue planet.

So which lucky ducks evolved one? Well, ducks for one. Warm-blooded birds and mammals cheerfully claim those bragging rights. They're joined by our cold-blooded, ectothermic friends, the fish, amphibians and reptiles. All these diverse lovelies share this characteristic.

And whether they now live at sea or on land, all of these lineages evolved from a marine organism somewhere down the line, then went on to develop a notochord and spinal column. Notochords are flexible rods that run down the length of chordates and vertebrates. They are handy adaptations for muscle attachment, helping with signalling and coordinating the development of the embryonic stage. The cells from the notochord play a key role in the development of the central nervous system and the formation of motor neurons and sensory cells. Alas, we often take our evolution for granted.

Let's take a moment to appreciate just how marvellous this evolutionary gift is and what it allows us to do. Your backbone gives your body structure, holds up that heavy skull of yours and connects your tasty brain to your body and organs. Eating, walking, fishing, hunting, your morning yoga class, are all made possible because of this adaptation. Pick pretty near anything you love to do and it is only possible because of your blessed spine.

And it sets us apart from our invertebrate friends.

While seventy thousand may seem like a large number, it represents less than three to five per cent of all described animal species. The rest is made up of the whopping 97%'ers, our dear invertebrates who include the arthropods (insects, arachnids, crustaceans, and myriapods), molluscs (our dear chitons, snails, bivalves, squid, and octopus), annelids (the often misunderstood earthworms and leeches), and cnidarians (our beautiful hydras, jellyfish, sea anemones, and corals). You'll notice that many of our invertebrate friends occur as tasty snacks. Having a backbone provides a supreme advantage to your placement in the food chain. Not always, as you may include fish and game on your menu. But generally, having a backbone means you're more likely to be holding the menu versus being listed as an appetizer. So, enjoy your Sunday 'downward dog' and thank your backbone for the magical gift it is.

HEXAGONAL COLUMNS: COOLING BASALT

The Giant's Causeway is a spectacular expanse of interlocking hexagonal basalt columns formed from volcanic eruptions during the Paleocene some 50-60 million years ago.

These columns tell a story of the cooling and freezing of the lava flows that formed them. As lava at the surface cools and freezes, it also shrinks as its molecules rearrange themselves into a solid structure. This happens much more quickly at the surface where the lava comes in contact with moist, cool air. As the basalt cools and shrinks, pressure increases in intensity and cracks begin to form. A way to dissipate this huge stress is to crack at an angle of 120 degrees, the angle that gives us a hexagon.

We see this beautifully illustrated at the Giant's Causeway in Ireland. Here, highly fluid molten basalt intruded through chalk beds which later cooled, contracted and cracked into hexagonal columns, creating a surreal visual against a dark and stormy Irish Sea.

DORIPPE SINICA OF JAPAN

A beautiful example of the decapod, Dorippe sinica, from Holocene deposits near Shizuoka, Japan. This regal fellow has a strongly sculptured carapace. He looks like he would have been quite the bruiser moving about on the seafloor looking for tasty snacks. He likely enjoyed just about any form of meat, potentially dining on fish, worms, eggs, squid, starfish or even a few of his slow-moving cousins.

The carapace is deeply grooved with conspicuous wart-like tubercles; anterolateral margin, between the base of the exorbital tooth and cervical groove, smooth, without tubercles or denticles.

The teeth on the lower orbital margin in the cluster. Carpus of cheliped distinctly granulated on the upper surface and with a conspicuous row of granules along the anterior margin. Though missing here, the merus of second and third pereiopods are almost cylindrical. (Türkay 1995). This specimen was collected and is the collection of the deeply awesome Takashi Ito of Japan

ARANDASPIDA: AGENTS OF SHIELD

The oldest and most primitive pteraspidomorphs were the Astraspida and the Arandaspida. You'll notice that all three of these taxon names contain 'aspid', which means shield.

These early fishes and many of the Pteraspidomorphi possessed large plates of dermal bone at the anterior end of their bodies. This dermal armour was very common in early vertebrates, but it was lost in their descendants. Arandaspida is represented by two well-known genera: Sacabampaspis, from South America and Arandaspis from Australia. Arandaspis have large, simple, dorsal and ventral head shields. Their bodies were fusiform, which means they were shaped sort of like a spindle, fat in the middle and tapering at both ends. Picture a sausage that is a bit wider near the centre with a crisp outer shell.

TYAUGHTON FOSSIL EXPOSURES

Our collecting area near the Tyaughton Fossil Exposures, Taseko Lakes, British Columbia, Canada. Tyaughton is kind of like El Dorado. Instead of immeasurable riches in gold, this region of the Chilcotin Mountains holds the treasures of time — bountiful Triassic-Jurassic fossils

TIKTAALIK OF ELLESMERE ISLAND

Tiktaalik was a fish with some advantageous tetrapod-like features that proved to be useful to an adaptation to land. Their head was detached from their shoulder girdle meaning they could lift their heads to take a look around. This was a new adaptation for our marine friends. The bones in the front limb were strong enough and adapted to support their bodies.

PAKICETUS: UNLIKELY WHALES

The unlikely creature bearing the title of "the first whale," is a fellow named Pakicetus. He is definitely not how we picture whales living today. Pakicetus is an extinct genus of cetaceans that lived about 50 million years ago.

They were mammals and looked like large rodents. They were also quite small by whale standards, reaching about four-feet in length. They ate meat, sometimes fish and are the ancestors of whales, porpoises and dolphins.

The only real clue of their connection to our aquatic friends is the shape of their skulls. Pakicetus had a long skull and an ear bone that is unique to whales. Oddly, they also had ankle bones that share characteristics with some of our even-toed mammals. They lived along the shores of a large shallow sea known as the Tethys. Although rare, there are several examples of mammals heading back to a life at sea.

DENMAN ISLAND CONCRETION

Northumberland Fm, Upper Cretaceous Nanaimo Group

A concretion found eroding out of the grey shales at Denman Island.

Thee Upper Cretaceous Nanaimo Group of southwest British Columbia is a >4 km-thick succession consisting mostly of deep marine siliciclastics deposited directly on the Insular Superterrane. As such, this succession has been the focus of several paleomagnetic, isotope geochemistry, paleontology, and sedimentology studies in attempts to elucidate the tectonic history and paleolatitude of the Insular Superterrane and associated entities during the critical time of Nanaimo Group deposition, 90 to 65 million years ago. The upper two-thirds of the succession is continuously and well exposed on Denman and Hornby islands and represents the best example of this part of the succession in the northern half of what we consider the single Nanaimo Basin. A concretion found on the beach at Denman, eroding out of the grey shales of the Upper Cretaceous Nanaimo Group

NOOTKA ISLAND

Nootka Sound, Photo: Dan Bowen

Rugged West Coast VIPS Fossil Field Trip to Late Eocene - Early Oligocene, Hesquiat formation of Nootka Island, west coast of Vancouver Island, British Columbia, Canada.

The area is known for its exceptional natural beauty and bounty of beautifully preserved decapod fossil specimens. The formation is named for the Hesquiaht people of the Nuu-chah-nulth, of Nootka Sound. The VIPS has led many research expeditions to remote sites on our West Coast. Their efforts have been rewarded with many new species being identified and excellent cooperation with paleontological researchers from around the globe.

BIODIVERSITY AT SEA AND ON LAND

Most of the Earth's surface is an ocean. When I think of the Earth, it is our oceans that I picture. Life began there. We began there. Most of the major animal groups can trace their lineage back to the seas and the Cambrian explosion, an orgy of breathtaking species diversification.

Since that time, a shocking half a billion years ago, our seas have played host to an astonishing array of species. If I'd visited our Earth back in the Cambrian, I would have bet good money that our watery planet's future was in the seas not on the land. But that 's not the case. Quite surprisingly, it is our humble rock and soil who now boast more species. Five times that of those living in the oceans. I know, shocking but true. Our oceans certainly had the running start on both numbers and diversity of species. But it is our fungi, our flowering plants, mindblowing variety of insects, trees, bees and fleas that make up the bulk of Earth's species these days.

It is something I'm interested in learning more about as it does not make good sense to me. 80 percent of Earth's species live on land today. About 15 percent call our oceans home and another 5% or so live in freshwater. Why more species live on land than in the ocean has puzzled others as well. Robert May, a zoologist at the University of Oxford, mulls this very question in an article from 1994 titled, “Biological Diversity: Differences between Land and Sea.” He continued with his research and published "The future of biological diversity in a crowded world," in Current Science, Vol. 82, No. 11 (10 June 2002), pp. 1325-1331.

Here he questions how well we know the plants, animals and micro-organisms with which we share this beautiful planet. His focus in the paper was to question how many species are there and how fast are some going extinct? You'll be interested to know that his best guess in 2002 was somewhere between 1.7 to 1.8 million. That's a considerable increase from Carl Linneaus' work back in 1758, the Swedish botanist, zoologist, and physician took a stab at the same question and came up with an estimate of about 9,000 species. While his numbers were off by a long margin, he did give us the binomial nomenclature system we use for naming organisms, so he still gets a hall pass.

May is a boy about town. His work is referenced everywhere. You may enjoy an article by the Atlantic from 2017 that delves into the topic for the lay audience with an eye to popularized reading.

FAVRET CANYON

Favret Canyon is considered one of the most important locations for the Middle Triassic (Anisian-Ladinian). It is a beautiful, yet desolate country. The roads are rough and the exposures are weathered out. The mountains bring a moodiness to the landscape and impact the weather.

We had stormy clouds, rain, sun, and afternoons of wind while walking through time and collecting marine fauna.

PRIMITIVE FISH OF THE CHENGJIANG LAGERSTÄTTE

Three genera of Lower Cambrian fish are known from the 530 million-year-old Chengjiang Lagerstätte in Yuxi, Yunnan Province, southern China. The locality is just north of Fuxian Lake and about a half-hour drive south from the city of Kunming.

• Haikouichthys ercaicunensis
• Myllokunmingia fengjiaoa
• Zhongjianichthys rostratus

The first two of these are fusiform in shape, whereas the third is eel-like. Myllokunnmingial and Haikouichthys have fusiform bodies and pairs of large eyes within the dorso-anterior lobe. Zhongjianichthys has eyes behind the dorso-anterior lobe.

A friend of mine, Eldon Grupp from the USA, found an 18 mm specimen on a mortality slab of Haikouella from Chengjiang. Apparently, no one had noticed it before shipping. Not surprising as Zhongjianichthys are easy to overlook. I've asked him if I can get a photo of that mortality plate to share with you. It's quite stunning. Haikouella, of course, are not vertebrates, but advanced craniate chordates. The specimen in question, however, was a vertebrate. Eldon has assigned this specimen to genus Zhongjianichthys based on its eel-like characteristics and its large eyes located behind the anterior or rostral lobe instead of within it. Even so, family affiliation is uncertain.

SIRENIA: MANATEES AND DUGONGS

I'd always grouped the dugongs and manatees together. There are slight differences between these two groups. Both groups belong to the order Sirenia. They shared a cousin in the Steller's sea cow, Hydrodamalis gigas, but that piece of their lineage was hunted to extinction by our species in the 18th century. Dugongs have tail flukes with pointed tips and manatees have paddle-shaped tails, similar to a Canadian Beaver.

Both of these lovelies from the order Sirenia went from terrestrial to marine, taking to the water in search of more prosperous pastures, as it were.

They are the extant and extinct forms of the oddball manatees and dugongs. They inhabit rivers and shallow coastal waters, making the best use of their fusiform bodies that lack dorsal fins and hind limbs. I've been thinking about them in the context of some of the primitive armoured fish we find in the Chengjiang biota of China, specifically those primitive species that were also fusiform.

We find dugongs today in waters near northern Australia and parts of the Indian and Pacific Oceans. They favour locations where seagrass, their food of choice, grows plentiful and they eat it roots and all. While seagrass low in fibre, high in nitrogen and easily digestible is preferred, dugongs will also dine on lower grade seagrass, algae and invertebrates should the opportunity arise. They've been known to eat jellyfish, sea squirts and shellfish over the course of their long lives. Some of the oldest dugongs have been known to live 70+ years, which is another statistic I find surprising. They are large, passive, have poor eyesight and look pretty tasty floating in the water; a defenceless floating buffet. Their population is in decline but yet they live on.

THE LURE OF THE SEA

Many land animals have returned to the sea throughout evolutionary history. We have beautifully documented cases from amphibians, reptiles, birds and mammals from over 30 different lineages over the past 250 million years.

Our dear penguins, seals, sea lions, walruses, whales, crocodiles and sea turtles were once entirely terrestrial. Some dipped a toe or two into freshwater ponds, but make no mistake, they were terrestrial. Each of these animals had ancestors that tried out the sea and decided to stay. They evolved and employed a variety of adaptations to meet their new saltwater challenges. Some adapted legs as fins, others became more streamlined, and still, others developed specialized organs to extract dissolved oxygen from the water through their skin or gills. The permutations are endless.

Returning to the sea comes with a whole host of benefits but some serious challenges as well. Life at sea is very different from life on land. Water is denser than air, impacting how an animal moves, sees and hears. More importantly, it impacts an air-breathing animal's movement on a pretty frequent basis. If you need air and haven't evolved gills, you need to surface frequently. Keeping your body temperature at a homeostatic level is also a challenge as water conducts heat much better than air. Even with all of these challenges, the lure of additional food sources and freedom of movement kept those who tried the sea in the sea and they evolved accordingly.

This is an interesting article from Alicia Ault writing for the Smithsonian who interviewed Nick Pysenson and Neil Kelley about some of their research that touches on this area. They published a paper on it in the journal Science back in 2015.

DEVONIAN JAWLESS FISH

Armoured Agnatha / Photo: Fossilero Fisher

This lovely specimen is an armoured agnatha jawless bony fish, Victoraspis longicornualis, from Lower Devonian deposits of Podolia, Ukraine.

Victoraspis longicornualis was named by Anders Carlsson and Henning Bloom back in 2008. The new osteostracan genus and species were described based on material from Rakovets' present-day Ukraine. This new taxon shares characteristics with the two genera Stensiopelta (Denison, 1951) and Zychaspis (Javier, 1985).

Agnatha is a superclass of vertebrates. This fellow looks quite different from our modern Agnatha, who include lamprey and hagfish. Ironically, hagfish are vertebrates who do not have vertebrae. Sometime in their evolution they lost them as they adapted to their environment.

ANDROGYNOCERAS OF YORKSHIRE

A stunning example of the ammonite Androgynoceras from the Yorkshire Coast, England.

The Geology of Yorkshire in northern England shows a very close relationship between the major topographical areas and the geological period in which their rocks were formed. The rocks of the Pennine chain of hills in the west are of Carboniferous origin whilst those of the central vale is Permo-Triassic.

The North York Moors in the north-east of the county are Jurassic in age while the Yorkshire Wolds to the south east are Cretaceous chalk uplands. The plain of Holderness and the Humberhead levels both owe their present form to the Quaternary ice ages. The strata become gradually younger from west to east. Much of Yorkshire presents heavily glaciated scenery as few places escaped the direct or indirect impact of the great ice sheets as they first advanced and then retreated during the last ice age. This beauty is in the collection of the deeply awesome Harry Tabiner.

FLAT CLAMS: BIOCHRONOLOGICAL MACROFOSSILS

Paper clams or 'flat clams' were widespread in the Triassic. We call these bivalves 'flat clams' because of their very thin shell width and narrow valve convexity. They often dominate the rocks in which they are found, as in these specimens from Pine Pass near Chetwynd in the Foothills of northeastern British Columbia.

Pine Pass is part of the Pardonet Formation. Just a short hike from the road we were able to easily find the abundant outcroppings of the paper clam, Monotis subcircularis, perfectly preserved and cemented in this strata from the Late Triassic. Because of their widespread distribution and very high species turnover rates, they make for excellent biochronological macrofossils, helping us to correlate biological events through time.

MCABEE FOSSIL BEDS: EOCENE KAMLOOPS GROUP

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 52-53 million years ago.

It is one of the best local sites in the province to experience a fossil dig first-hand. It's an easy 4-hour drive from Vancouver and easily done as a rather longish day trip. I headed up there this past weekend with some wonderful enthusiastic crew. 

The site was designated a Provincial Heritage Site under British Columbia's Heritage Conservation Act in July of 2012. The site was reopened to public tours and viewing this summer with plans to build out a visitor's centre and educational programs in the future.

We were greeted on the day by two wonderful hosts from the Bonaparte Band, Gayle Pierro and Leroy Antoine. Both were very welcoming and informative, sharing the lay of the land, a bit of their history with the workings and offering us a guided tour. 

From the road, it is a short drive up to the first staging area that houses visitor parking and a public washroom. The first Site Information station is a short stroll away and includes a tent with a table and maps showing plans for the site. Here, Gayle walked us through the vision for McAbee and showed us a selection of some of the species found here. 

We were asked to stop back on the way down and fill out a survey that asked about our experience and provide feedback that will help shape what McAbee is to become. A short hike up the hill towards the hoodoos leads to another staging area. Here, Leroy was our host and guide. He shared a bit more about the geology of the area and showed us specimens found over the summer.

As McAbee is a Heritage Site, their only request was that we stay within the marked area and trails and keep ourselves safe. Here safe means hydrated, shaded from the sun and avoiding both the resident rattlesnakes and cacti. McAbee offers an excellent opportunity for education and outreach both for locals and the larger community. It was very enjoyable to see the reactions of those visiting the site as they took in the wonderful diversity of fossil species and learning about the local history from our hosts.

The Province is committed to providing access to the site to scientists and the lay public. The direction on what happens next at McAbee is being driven by the Heritage Branch in consultation with members of the Shuswap Nation and Bonaparte Band. Bonaparte's traditional territory is located within the Shuswap Nation. Local members of the Bonaparte Band are Secwepemc. They would like to share the spiritual significance of the area from a Secwepemc First Nation perspective and see McAbee as an indigenous tourism destination. So it looks like it will be paleontology, archaeology with a cultural focus to add spice. In any case, fossil viewing, and hopefully supervised collecting will continue with oversight to ensure significant fossil finds make their way to science.

It would be good to see McAbee take a page out of the Courtney and District Museum's playbook. You'll recall that it was the Puntledge Elasmosaur that sparked the expansion of that museum and inspired a whole host of outreach and educational programs. The Courtenay Museum has been offering paid guided tours to the elasmosaur heritage site for over a dozen years. 

They are members of the British Columbia Paleontological Alliance (BCPA), a union of professional and amateur paleontological organizations working to advance the science of paleontology in the province by fostering public awareness, scientific collecting and education, and by promoting communication among all those interested in fossils. Within that context, the Courtenay Museum are bound both by the BCPA constitution and bylaws, and of course, the laws around fossil collecting in British Columbia.

One of the sister sites to McAbee, the Driftwood Canyon Provincial Park Fossil Beds, offers an honours system for their site. Visitors may handle and view fossils but are asked to not take them home. Both Driftwood Canyon and McAbee are part of an arc of Eocene lakebed sites that extend from Smithers in the north, down to the fossil site of Republic Washington, in the south. The grouping includes the fossil sites of Driftwood Canyon, Quilchena, Allenby, Tranquille, McAbee, Princeton and Republic. Each of these localities provides important clues to our ancient climate.

The fossils range in age from Early to Middle Eocene. McAbee had a more temperate climate, slightly cooler and wetter than other Eocene sites to the south at Princeton, British Columbia, Republic in north-central Washington, in the Swauk Formation near Skykomish and the Chuckanut Formation of northern Washington state. The McAbee fossil beds consist of 30 metres of fossiliferous shale in the Eocene Kamloops Group.

The fossils are preserved here as impressions and carbonaceous films. We see gymnosperm (16 species); a variety of conifers (14 species to my knowledge); two species of ginkgo, a large variety of angiosperm (67 species); a variety of insects and fish remains, the rare feather and a boatload of mashed deciduous material. Nuts and cupules are also found from the dicotyledonous Fagus and Ulmus and members of the Betulaceae, including Betula and Alnus.

We see many species that look very similar to those growing in the Pacific Northwest today. Specifically, cypress, dawn redwood, fir, spruce, pine, larch, hemlock, alder, birch, dogwood, beech, sassafras, cottonwood, maple, elm and grape. If we look at the pollen data, we see over a hundred highly probable species from the site. Though rare, McAbee has also produced spiders, birds (and lovely individual feathers) along with multiple specimens of the freshwater crayfish, Aenigmastacus crandalli.

For insects, we see dragonflies, damselflies, cockroaches, termites, earwigs, aphids, leafhoppers, spittlebugs, lacewings, a variety of beetles, gnats, ants, hornets, stick insects, water striders, weevils, wasps and March flies. The insects are particularly well-preserved. Missing are the tropical Sabal (palm), seen at Princeton and the impressive Ensete (banana) and Zamiaceae (cycad) found at Eocene sites in Republic and Chuckanut, Washington.

McAbee is located just east of Cache Creek, just north of and visible from Highway 1/97. 14.5 km to be exact and exactly the distance you need to drink one large coffee and then need a washroom. You'll be pleased to know they have installed one at the site. McAbee is a site for hiking boots, hand, head and eye protection. They have a few resident rattlesnakes and prickly cacti to keep you on your toes. Keep yourself safe and well-hydrated.

As you drive up, you'll see telltale hoodoos on the ridge to let you know you've reached the right spot. If you have a GPS, pop in these coordinates and you're on your way. 50°47.831′N 121°8.469′W.

NORTHUMBERLAND FORMATION

The late Cretaceous ammonite Pachydiscus suchiaensis found in concretion amongst the 72 million-year-old grey shales of the Northumberland Formation, Campanian to the lower Maastrichtian, part of the upper Cretaceous, from Collishaw Point (Boulder Point to the locals), northwest side of Hornby Island, southwestern British Columbia.

Hornby is a glorious place to collect. 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. A new species of pterosaur (flying reptile) Gwawinapterus beardi was found on the same beach site and named after Graham Beard, a local collector, author and great friend.

Like most of the fossils found at this locality, the specimen was 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. If you are lucky, when you split them you see a fossil hidden within. The main topographic feature on Hornby Island is an arcuate mountain consisting 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 consists of a structurally simple 700-foot conglomerate 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.

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 forming 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.

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.

HADROSAURUS: DUCK-BILLED DINOSAURS

Hadrosaurus, also known as the "duck-billed" dinosaurs, were a very successful group of plant-eaters that thrived throughout western Canada during the late Cretaceous, some 70 to 84 million years ago. Hadrosaurs may have lived as part of a herd, dining on pine needles, twigs and flowering plants.

There are two main groups of Hadrosaurs, crested and non-crested. The bony crest on the top of the head of the hadrosaurs was hollow and attached to the nasal passages. It is thought that the hollow crest was used to make different sounds. These sounds may have signalled distress or been the mating calls used to attract mates.

This beautiful specimen graces the back galleries of the Courtenay and District Museum on Vancouver Island, British Columbia, Canada. This fellow has kissing cousins over in the state of New Jersey where this species is the official state fossil. The first of his kind was found by John Estaugh Hopkins in New Jersey back in 1838.

GREEN RIVER HETEROPTERAN

A delightful Heteropteran collected this past week by Jim Barkley from Eocene exposures of the Green River Formation of Western Colorado, which was once the bottom of an extensive series of Eocene lakes.

The Green River Formation is particularly abundant in beautifully preserved fossil fish, eleven species of reptiles including a 13.5ft crocodile, an armadillo-like mammal, Brachianodon westorum, bats, birds and other freshwater aquatic goodies.

CARNOTAURUS OF ARGENTINA

Carnotaurus sastrei, a genus of large theropod dinosaur that roamed, Argentina, South America during the Late Cretaceous period, 72 to 69.9 million years ago.

This fellow (or at least his skull) is on display at the Natural History Museum in Madrid, Spain. For now, he is the only known genus of this species of bipedal predator.

The skull is quite unusual. Initially, it has a very marine reptile feel (but make no mistake this guy is clearly a terrestrial theropod). Once you look closer you see his bull-like horns (from whence he gets his name) that imply battle between rivals for the best meal, sexual partner and to be the one who leads the herd.

RIOMAGGIORE: SUNSETS AND SQUID INK

Riomaggiore or 'Rimazuu' in the local Ligurian language, is a lovely seaside village that can trace its roots to the good taste of Monks who settled here in the early thirteenth century.

Here, great wine is produced and consumed along with a huge variety of seafood, figs, olives, capers and Limoncello in the wee restaurants and bars along the Via Colombo that look out onto the Gulf of Genoa. Inspired by the praise of Dante, Petrarch and Boccaccio, I had the great pleasure to venture there years ago, prior to the huge slides that plagued the Cinque Terre. I ate one of my finest meals, a pasta made from squid ink, one evening I was there. Drawn to the picturesque beauty of the Liguria region, ancient vineyards and the irresistible "photo a moment" scenery, we travelled from village-to-village, all along the Cinque Terre.

Liguria remains one of the wildest parts of the Ligurian littoral east of Genoa. The coastline is home to incredibly complex and exciting geology. It is composed of the Maritime Alps in the west and the Ligurian "nappies," continental margin ophiolites, of the Apennines in the east.

Along the coast, the north-northwest convergence of the Alpine orogeny gives way to the active east-northeast convergence along the Apennines. All of this tasty geology can be observed while walking from town to town from Riomaggiore through Manarola, Corniglia and Vernazza. We stayed in Monterosso al Mare during our visit, meeting up with friends and then visiting them in their home city of Milan. If one is lucky enough to be invited as a guest, the geology of the Via dell Amore is true to its namesake and well worth the trip.
