HORNBY ISLAND FOSSIL CEPHALOPODS

Diplomoceras sp.

This gorgeous cream and brown big beast of a heteromorph, Diplomoceras (Diplomoceras) sp., (Hyatt, 1900) was found within the 72 million-year-old sediments of the upper Nanaimo Group on the northern Gulf Island of Hornby in southwestern British Columbia, Canada. 

The site is known as Boulder Point to the locals and it has been a popular fossil destination for many years. It is the home of the K'ómoks First Nation, who called the island Ja-dai-aich.

Many of the fossils found at this locality are discovered 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 these nodules you are rewarded with a fossil hidden within. That is not always the case but the rewards are worth the effort. 

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

And so it was in the first warm days of early summer last year. Three members of the Vancouver Palaeontological Society excavated this 100 cm long fossil specimen over two days in June of 2020. The specimen was not in concretion but rather embedded in the hard sintered shale matrix beneath their feet. It was angled slightly downward towards the shoreline and locked within the rolling shale beds of the island. 

Diplomoceratidae (Spath, 1926) are often referred to as the paperclip ammonites. They are in the family of ammonites included in the order Ammonitida in the Class Cephalopoda and are found within marine offshore to shallow subtidal Cretaceous — 99.7 to 66.043 million-year-old — sediments worldwide. 

I was reading with interest this morning about a new find published by Muramiya and Shigeta in December 2020 of a new heteromorph ammonoid Sormaites teshioensis gen. et sp. nov. (Diplomoceratidae) described from the upper Turonian (Upper Cretaceous) in the Nakagawa area, Hokkaido, northern Japan. This lovely has a shell surface ornamented with simple, straight, sharp-tipped ribs throughout ontogeny, but infrequent flared ribs and constrictions occur on later whorls. Excluding its earliest whorls, its coiling and ornamentation are very similar to Scalarites mihoensis and Sc. densicostatus from the Turonian to Coniacian in Hokkaido and Sakhalin, suggesting that So. teshioensis was probably derived from one of these taxa in the Northwest Pacific during middle to late Turonian.

Much like the long-lived geoducks living in Puget Sound today, studies of Diplomoceras suggest that members of this family could live to be over 200 years old — a good 40-years longer than a geoduck but not nearly as long-lived as the extant bivalve Arctica islandica that reach 405 to 410 years in age. 

Along with this jaw-dropper of a heteromorph, the same group found an Actinosepia, gladius — internal hard body part found in many cephalopods of a Vampyropod. Vampyropods are members of the proposed group Vampyropoda — equivalent to the superorder Octopodiformes — which includes vampire squid and octopus.

The upper Nanaimo Group is a mix of marine sandstone, conglomerate and shale. These are partially exposed in the Campanian to the lower Maastrichtian outcrops at Collishaw Point on the northwest side of Hornby Island.

Along with fossil crabs, shark teeth, bivalves and occasional rare and exquisite saurodontid fish, an ambush predator with very sharp serrated teeth and elongate, torpedo-like body — we also find three heteromorph ammonite families are represented within the massive, dark-grey mudstones interlaminated and interbedded with siltstone and fine-grained sandstone of the upper Campanian (Upper Cretaceous) strata of the Northumberland Formation exposed here: Baculitidae, Diplomoceratidae and Nostoceratidae. 

A variety of species are distinguished within these families, of which only three taxa – Baculites occidentalis (Meek, 1862), Diplomoceras (Diplomoceras) cylindraceum (Defrance, 1816) and Nostoceras (Nostoceras) hornbyense (Whiteaves, 1895), have been studied and reported previously. 

Over the last decade, large new collections by many members of the Vancouver Island Palaeontological Society and palaeontologists working at the Geologic Survey of Canada, along with a renewed look at previous collections have provided new taxonomic and morphometric data for the Hornby Island ammonite fauna. This renewed lens has helped shape our understanding and revamp descriptions of heteromorph taxa. Eleven taxa are recognized, including the new species Exiteloceras (Exiteloceras) densicostatum sp. nov., Nostoceras (Didymoceras?) adrotans sp. nov. and Solenoceras exornatus sp. nov. 

A great variety of shape and form exist within each group. Morphometric analyses by Sandy McLachlan and Jim Haggart of over 700 specimens unveiled the considerable phenotypic plasticity of these ammonites. They exhibit an extraordinarily broad spectrum of variability in their ornamentation and shell dimensions. 

The presence of a vibrant amateur palaeontological community on Vancouver Island made the extent of their work possible. Graham Beard, Doug Carrick, Betty Franklin, Raymond Graham, Joe Haegert, Bob Hunt, Stevi Kittleson, Kurt Morrison and Jean Sibbald are thanked for their correspondence and generosity in contributing many of the exquisite specimens featured in that study. 

These generous individuals, along with many other members of the Vancouver Island Palaeontological Society (VIPS), Vancouver Paleontological Society (VanPS), and British Columbia Paleontological Alliance (BCPA), have contributed a great deal to our knowledge of the West Coast of Canada and her geologic and palaeontological correlations to the rest of the world; notably, Dan Bowen, Rick Ross, John Fam and Pat and Mike Trask, Naomi & Terry Thomas. Their diligence in the collection, preparation and documentation of macrofossils is a reflection of the passion they have for palaeontology and their will to help shape the narrative of Earth history.

Through their efforts, a large population sample of Nostoceras (Nostoceras) hornbyense was made available and provided an excellent case study of a member of the Nostoceratidae. It was through the well-documented collection and examination of a remarkable number of nearly complete, well-preserved specimens that a re-evaluation of diagnostic traits within the genus Nostoceras was made possible. 

The north-east Pacific Nostoceras (Nostoceras) hornbyense Zone and the global Nostoceras (Nostoceras) hyatti Assemblage Zone are regarded as correlative, reinforcing a late Campanian age for the Northumberland Formation. This builds on the earlier work of individuals like Alan McGugan and others. McGugan looked at the Upper Cretaceous (Campanian and Maastrichtian) Foraminifera from the Upper Lambert and Northumberland Formations, Gulf Islands, British Columbia, Canada.

The Maastrichtian Bolivina incrassata fauna (upper part of Upper Lambert Formation) of Hornby Island (northern Comox Basin) is now recognized in the southern Nanaimo Basin on Gabriola and Galiano Islands. The Maastrichtian planktonic index species Globotruncana contusa occurs in the Upper Northumberland Formation of Mayne Island and Globotruncana calcarata (uppermost Campanian) occurs| in the Upper Northumberland Formation of Mayne Island and also in the Upper Lambert Formation at Manning Point on the north shore of Hornby Island (Comox Basin).

Very abundant benthonic and planktonic foraminiferal assemblages from the Upper Campanian Lower Northumberland Formation of Mayne Island enable paleoecological interpretations to be made using the Fisher diversity index, triangular plots of Texturlariina/Rotaliina/Miliolina, calcareous/agglutinated ratios, planktonic/benthonic ratios, generic models, and associated microfossils and megafossils. 

Combined with local geology and stratigraphy a relatively shallow neritic depositional environment is proposed for the Northumberland Formation in agreement with Scott but not Sliter who proposed an Outer shelf/slope environment with depths of 300 m or more.

QUINTUS SERTORIUS AND THE MYTH OF ANTAEUS

Tetralophodon

During the Miocene and Pliocene, 12-1.6 million years ago, a diverse group of extinct proboscideans, elephant-like animals walked the Earth.

Most of these large beasts had four tusks and likely a trunk similar to modern elephants. They were creatures of legend, inspiring myths and stories of fanciful creatures to the first humans to encounter them.

Beyond our Neanderthal friends, one such fellow was Quintus Sertorius, a Roman statesman come general, who grew up in Umbria. Born into a world at war just two years before the Romans sacked Corinth to bring Greece under Roman rule, Quintus lived much of his life as a military man far from his native Norcia. Around 81 BC, he travelled to Morocco, the land of opium, massive trilobites and the birthplace of Antaeus, the legendary North African ogre who was killed by the Greek hero Heracles.

The locals tell a tale that Quintus requested proof of Antaeus, hard evidence he could bring back to Rome to support their tales so they took him to a mound near Tingis, the ancient name for Tangier, Morocco. It was here they unearthed the bones of an extinct elephantoid, Tetralophodon.

Tetralophodon bones are large and skeletons singularly impressive. Impressive enough to be taken for something else entirely. By all accounts, these proboscidean remains were that of the mythical giant, Antaeus, son of the gods Poseidon and Gaea and were thus reported back to Rome as such. Antaeus went on to marry the goddess Tinge and it is from her, in part, that Tangier in northwestern Morocco gets its name. Together, Antaeus and Tinge had a son, Sophax. He is credited with having the North Africa city take her name. Rome was satisfied with the find. It would be hundreds of years later before the bones true ancestry was known and in that time, many more wonderful ancient proboscideans remains were unearthed..

There were other early proboscideans, of course. The earliest known proboscidean is Eritherium, followed by Phosphatherium, a small animal about the size of a fox. Both date from late Paleocene deposits of Morocco.

Proboscideans evolved in Africa, where they increased in size and diversity during the Eocene and early Oligocene. Several primitive families from these epochs have been described, including the Numidotheriidae, Moeritheriidae, and Barytheriidae, all found exclusively in Africa. 

The Anthracobunidae from the Indian subcontinent were also believed to be a family of proboscideans, but were excluded from the Proboscidea by Shoshani and Tassy (2005) and have more recently been assigned to the Perissodactyla.

When Africa became connected to Europe and Asia after the shrinking of the Tethys Sea, proboscideans migrated into Eurasia, with some families eventually reaching the Americas. Proboscideans found in Eurasia as well as Africa include the Deinotheriidae, which thrived during the Miocene and into the early Quaternary, Stegolophodon, an early genus of the disputed family Stegodontidae; the highly diverse Gomphotheriidae and Amebelodontidae; and the much loved Mammutidae, or mastodons.

I traveled and hiked through much of Morocco to explore the countryside, ancient Roman ruins and many splendid outcrops when I was eighteen. I wish I had known more of the fossil sites before that trip but many had yet to be discovered. I will share more of those stories — and there are plenty — in future posts.

BARNACLES: K'WIT'A'A

One of the most interesting and enigmatic little critters we find at the seashore are barnacles. They cling to rocks deep in the sea and at the waters' edge, closed to our curiosity, their domed mounds like little closed beaks shut to the water and the world.

They choose their permanent homes as larvae, sticking to hard substrates that will become their permanent homes for the rest of their lives. It has taken us a long time to find how they actually stick or what kind of "glue" they were using.

Remarkably, the barnacle glue sticks to rocks in a similar way to how red cells bind together. Red blood cells bind and clot with a little help from some enzymes. 

These work to create long protein fibres that first blind, clot then form a scab. The mechanism barnacles use, right down to the enzyme, is very similar. That's especially interesting as about a billion years separate our evolutionary path from theirs.

So, with the help of their clever enzymes, they can affix to most anything – ship hulls, rocks, and even the skin of whales. If you find them in tidepools, you begin to see their true nature as they open up, their delicate feathery finger-like projections flowing back and forth in the surf.

One of my earliest memories is of playing with them in the tidepools on the north end of Vancouver Island. It was here that I learned their many names. In the Kwak'wala language of the Kwakiutl First Nations of the Pacific Northwest, the word for barnacles is k̕wit̕a̱'a — and if it is a very small barnacle it is called t̕sot̕soma — and the Kwak'wala word for glue is ḵ̕wa̱dayu.

MAMMOTH OF WRANGEL ISLAND

Mammoth Tusk, Wrangel Island, Arctic Ocean

This tusk is from Mammutus primigenius, our beloved Woolly Mammoths, from Wrangel Island in the Arctic Ocean.  He was a true elephant, unlike his less robust cousins, the mastodons. 

Mammoths were bigger — both in girth and height — weighing in at a max of 13 tonnes. If you stood beside him and reached way up, you might be able to touch his tusks but likely not reach up to his mouth or even his eyes. 

He would have had a shaggy coat of light or dark coloured hair with long outer hair strands covering a dense thick undercoat. His oil glands would have worked overtime to secrete oils, giving him natural — and I'm guessing stinky — waterproofing.

Some of the hair strands we have recovered are more than a meter in length. These behemoth proboscideans boasted long, curved tusks, little ears, short tails and grazed on leaves, shrubs and grasses that would have been work to get at as much of the northern hemisphere was covered in ice and snow during his reign. It is often the teeth of mammoths like those you see in the photo here that we see displayed. 

Woolly Mammoths, Mammutus primigenius

Their molar teeth were large and have always struck me as looking like ink plates from a printing press. 

If they are allowed to dry out in collection, they fall apart into discreet plates that can be mistaken for mineralized or calcified rock and not the bits and pieces of mammoth molars that they indeed are. 

Their large surface area was perfect for grinding down the low nutrient, but for the most part, plentiful grasses that sustained them.

How did they use their tusks? Likely for displays of strength, protecting their delicate trunks, digging up ground vegetation and in dry riverbeds, digging holes to get at the precious life-giving water. It's a genius design, really. A bit like having a plough on the front of your skull. In the photo above you can see a tusk washed clean in a creek bed on Wrangel Island.

Their size offered protection against other predators once the mammoth was full grown. Sadly for the juveniles, they offered meaty, tasty prey to big cats like Homotherium who roamed those ancient grasslands alongside them.

They roamed widely in the Pliocene to Holocene, roaming much of Africa, Europe, Asia and North America. We see them first some 150,000 years ago from remains in Russia then expanding out from Spain to Alaska. They enjoyed a very long lifespan of 60-80 — up to 20 years longer than a mastodon and longer than modern elephants. They enjoyed the prime position as the Apex predator of the megafauna, then declined — partially because of the environment and food resources and partially because of their co-existence with humans. 

In places where the fossil record shows a preference for hunting smaller prey, humans and megafauna do better together. We see this in places like the Indian Subcontinent where primates and rodents made the menu more often than the large megafauna who roamed there. We also see this in present-day Africa, where the last of the large and lovely megafauna show remarkable resilience in the face of human co-existence.  

The woolly mammoths from the Ukrainian-Russian plains died out 15,000 years ago. This population was followed by woolly mammoths from St. Paul Island in Alaska who died out 5,600 years ago — and quite surprisingly, at least to me, the last mammoth died just 4,000 years ago in the frosty ice on the small of Wrangel in the Arctic Ocean.

PORPOISE: KULUT'A

Dall's Porpoise

These delightfully friendly and super smart fellows are Dall's porpoise. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, a blowhole is known as a ka̱'was, whether on a dolphin (porpoise) or whale and a porpoise is known as a k̓ulut̕a. 

In the Pacific Northwest, we see many of their kind — the shy, blunt-nosed harbour porpoise, the social and herd-minded Pacific white-sided dolphin and the showy and social Dall's porpoise.  

Of these, the Dall's porpoise is a particular favourite. These speedy muscular black and white showboats like to ride the bow waves of passing boats — something they clearly enjoy and a thrill for everyone on board the vessel. If you slow down, they will often whisk away, but give them a chance to race you and they may stay with you all afternoon. 

Harbour porpoises are the complete opposite. You are much more likely to see their solid black bodies and wee fin skimming through the waves across the bay as they try to avoid you entirely. Harbour porpoise prefer quiet sheltered shorelines, often exploring solo or in small groups of two or three. 

We sometimes see these lovely marine mammals represented in the art of the First Nations in the Pacific Northwest, particularly along the coast of British Columbia. You will know them from their rather rectangular artistic depiction with a pronounced snout and lacking teeth (though they have them) used to portray killer whales or orca. 

As a group, even considering the shy Harbour porpoise, these marine mammals are social and playful. Humpback whales are fond of them and you will sometimes see them hanging out altogether in the bays and inlets or near the shore. 

They are quite vocal, making lots of distinctive and interesting noises in the water. They squeak, squawk and use body language — leaping from the water while snapping their jaws and slapping their tails on the surface. They love to blow bubbles, will swim right up to you for a kiss and cuddle. 

Each individual has a signature sound, a whistle that is uniquely their own. They use these whistles to tell one of their friends and family members from another.

Porpoise are marine mammals that live in our world's oceans. If it is salty and cold, you can be pretty sure they are there. They breathe air at the surface, similar to humans, using their lungs and inhaling and exhaling through a blowhole at the top of their heads instead of through their snouts. 

ROCK LOBSTER: HOMARUS

An artfully enhanced example of Homarus hakelensis, an extinct genus of fossil lobster belonging to the family Nephrophidae. Homarus is a genus of lobsters, which include the common and commercially significant species Homarus americanus (the American lobster) and Homarus gammarus (the European lobster).

The Cape lobster, which was formerly in this genus as H. capensis, was moved in 1995 to the new genus Homarinus.

Lobsters have long bodies with muscular tails and live in crevices or burrows on the seafloor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others.

Highly prized as seafood, lobsters are economically important and are often one of the most profitable commodities in coastal areas they populate. Commercially important species include two species of Homarus — which looks more like the stereotypical lobster — from the northern Atlantic Ocean, and scampi — which looks more like a shrimp — the Northern Hemisphere genus Nephrops and the Southern Hemisphere genus Metanephrops. Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term lobster generally refers to the clawed lobsters of the family Nephropidae.

Clawed lobsters are not closely related to spiny lobsters or slipper lobsters, which have no claws or chelae, or to squat lobsters. The closest living relatives of clawed lobsters are the reef lobsters and the three families of freshwater crayfish. 

This cutie was found in Cretaceous outcrops at Hâdjoula. The sub‐lithographical limestones of Hâqel and Hâdjoula, in northwest Lebanon, produce beautifully preserved shrimp, fish, and octopus. The localities are about 15 km apart, 45 km away from Beirut and 15 km away from the coastal city of Jbail. 

NEVADA FOSSILS: CARNIAN-NORIAN BOUNDARY

Time Slows at Berlin-Ichthyosaur State Park

High on the hillside up a long entry road sits the entrance to Berlin-Ichthyosaur State Park in central Nevada.

A worn American flag and sun bleached outbuildings greet you on your way to the outcrops. Away from the hustle and bustle that define the rest of Nevada this place feels remarkably serene. Your eyes squint against the sun as you search for ammonoids and other marine fossil fauna while your nose tends to the assault from the bracing smell of sage brush.

This site holds many stories. The interpretive centre displays wonderful marine reptiles, ichthyosaurs in situ, as you might expect from the name of the park — but it also showcases years of history lovingly tended. This stretch of dry golden low hills dappled with the yellow of creosote and desert grasses is an important locality for our understanding of the Carnian-Norian boundary (CNB) in North America.

The area is known worldwide as one of the most important ichthyosaur Fossil-Lagerstätte because of the sheer volume of remarkably well-preserved, fully articulated (all the sweet bones laid out all in a row...) specimens of Shonisaurus popularis.

Rich ammonoid faunas outcrop in the barren hills of the Upper Triassic (Early Norian, Kerri zone), Luning Formation, West Union Canyon, Nevada. They were studied by N. J. Silberling (1959) and provide support for the definition of the Schucherti and Macrolobatus zones of the latest Carnian — which are here overlain by well-preserved faunas of the earliest Norian Kerri Zone. 

The genus Gonionotites, very common in the Tethys and British Columbia, is for the moment, unknown in Nevada. The Upper Carnian faunas are dominated by Tropitidae, while Juvavitidae are conspicuously lacking. 

Middle Triassic Ammonoids

Despite its importance, no further investigations had been done at this site for a good 50 years. That changed in 2010 when Jim Haggart, Mike Orchard and Paul Smith — all local Vancouverites — collaborated on a project that took them down to Nevada to look at the conodonts and ammonoids. They did a bed-by-bed sampling of ammonoids and conodonts in West Union Canyon during October of that year.

October is an ideal time to do fieldwork in this area. There are a few good weeks between screaming hot and frigid cold. It is also tarantula breeding season so keep your eyes peeled. Those sweet little burrows you see are not from rodents but rather largish arachnids. 

The eastern side of the canyon provides the best record of the Macrolobatus Zone, which is represented by several beds yielding ammonoids of the Tropites group, together with Anatropites div. sp. 

Conodont faunas from both these and higher beds are dominated by ornate metapolygnthids that would formerly have been collectively referred to Metapolygnathus primitius, a species long known to straddle the CNB. Within this lower part of the section, they resemble forms that have been separated as Metapolygnathus mersinensis. Slightly higher, forms close to Epigondolella' orchardi and a single Orchardella n. sp. occur. This association can be correlated with the latest Carnian in British Columbia.

Higher in the section, the ammonoid fauna shows a sudden change and is dominated by Tropithisbites. Few tens of metres above, but slightly below the first occurrence of Norian ammonoids Guembelites jandianus and Stikinoceras, two new species of conodonts (Gen et sp. nov. A and B) appear that also occur close to the favoured Carnian/Norian boundary at Black Bear Ridge, British Columbia. Stratigraphically higher collections continue to be dominated by forms close to M. mersinensis and E. orchardi after BC's own Mike Orchard.

The best exposure of the Kerri Zone is on the western side of the West Union Canyon. Ammonoids, dominated by Guembelites and Stikinoceras div. sp., have been collected from several fossil-bearing levels. Conodont faunas replicate those of the east section. The collected ammonoids fit perfectly well with the faunas described by Silberling in 1959, but they differ somewhat from coeval faunas of the Tethys and Canada. 

The ammonoid fauna paints a compelling picture of Tethyan influence with a series of smoking guns. We see an abundance of Tropitidae in the Carnian, a lack of Pterosirenites in the Norian, copious Guembelites, the Tethyan species G. philostrati, the stratigraphic position of G. clavatus and the rare occurrence of Gonionotites. Their hallelujah moment was likely finding an undescribed species of the thin-shelled bivalve Halobia similar to Halobia beyrichi — the clincher that perhaps seals this deal on Tethyan influence. 

I'll take a boo to see what Christopher McRoberts published on the find. A jolly good idea to have him on this expedition as it would have been easy to overlook if the focus remained solely on the conodonts and ammonoids. McRoberts has published on the much-studied Pardonet Formation up in the Willison Lake Area of Northeastern, British Columbia. He knows a thing or two about Upper Triassic Bivalvia and the correlation to coeval faunas elsewhere in the North American Cordillera, and to the Boreal, Panthalassan and Tethyan faunal realms. 

If you fancy a read, they published a paper: "Towards the definition of the Carnian/Norian Boundary: New data on Ammonoids and Conodonts from central Nevada," which you can find in the proceedings of the 21st Canadian Paleontology Conference; by Haggart, J W (ed.); Smith, P L (ed.); Canadian Paleontology Conference Proceedings no. 9, 2011 p. 9-10.

Marco Balini, James Jenks, Riccardo Martin, Christopher McRoberts, along with Mike Orchard and Norman Siberling, did a bed by bed sampling in 2013 and published on The Carnian/Norian boundary succession at Berlin-Ichthyosaur State Park (Upper Triassic, central Nevada, USA) and published in January 2014 in Paläontologische Zeitschrift 89:399–433. That work is available for download from ResearchGate. The original is in German, but there is a translation available.

After years of reading about the correlation between British Columbia and Nevada, I had the very great pleasure of walking through these same sections in October 2019 with members of the Vancouver Paleontological Society and Vancouver Island Palaeontological Society. It was with that same crew that I'd originally explored fossil sites in the Canadian Rockies in the early 2000s. Those early trips led to paper after paper and the exciting revelations that inspired our Nevada adventure.

If you plan your own adventure, you'll want to keep an eye out for some of the other modern fauna — mountain lions, snakes, lizards, scorpions, wolves, coyotes, foxes, ground squirrels, rabbits, falcons, hawks, eagles, bobcats, sheep, deer and pronghorns.

NIOBE SCHMIDTI OF NORWAY

Niobe schmidti (Balashova, 1976)

This gorgeous trilobite is an exceptionally well-preserved Niobe schmidti (Balashova, 1976) from middle Ordovician limestone deposits of the Huk Formation, Lysaker member near Oslo, Norway. 

The limestones of the Huk Formation have an extreme geological history and fossils from this formation are usually very difficult to prepare. 

The beige/grey limestones are often heavily cemented to the shelly material, which can be quite fragile.

The rich chocolate coloured specimen you see here was no exception. It presented many challenges in its 26 hours of preparation but each of these was overcome by the patience and skill of Paul Freitag Wolvers at Freitag Fossils. 

I have added a link below with a series of photos so you can walk through the preparation process step by step with Paul. If you have a special specimen you would like prepped, I highly recommend you contact him. His work is outstanding.

Superb prep of this Niobe schmidti (Balashova, 1976)

The shell was partly hollow, very fragile and stuck firmly to the matrix. The positive was assembled from two pieces and much of the shell of the left half of the trilobite had to be transferred over from the negative — no small feat. 

Despite these challenges, the final result is superb. This Niobe schmidti is a museum-quality specimen with exquisite preservation. You can clearly see the lovely terrace lines, pores and eye lenses are excellent to study.  

This specimen hails from the middle Ordovician. The Ordovician lasted almost 45 million years, beginning 488.3 million years ago and ending 443.7 million years ago. 

It was the time in our Earth's history when the area north of the tropics was almost entirely underwater and most of the world's land was collected into the southern supercontinent of Gondwana. Throughout the Ordovician, Gondwana slowly shifted towards the South Pole and much of it remained submerged under an ancient ocean.

Niobe schmidti (Balashova, 1976)

At the time that this fellow was making a living in our ancient seas, he would have been joined by a diverse community of marine invertebrates —graptolites, fellow trilobites, brachiopods and the early vertebrate conodonts. 

These marine communities were joined by red and green algae, primitive fish, cephalopods, corals, crinoids, and gastropods. 

We also find stunning tetrahedral spores similar to those of primitive land plants which tell us who was living on the land at the time.

One of the first specimens of this lovely species I had the pleasure to see was from the Voybokalo Quarry near St. Petersburg in Russia. These outcrops are part of the Kunda Horizon, Lower Ordovician, Asaphus expansus zone and run roughly 468 million years old. 

From the Lower to Middle Ordovician, the Earth was enjoying a mild, humid climate — the weather was warm and the atmosphere contained a significant amount of moisture. 

Once Gondwana finally settled on the South Pole during the Upper Ordovician, massive glaciers formed. These drained the shallow seas and ocean levels dropped. By the end of the Ordovician, 60% of all marine invertebrates and 25% of all life on Earth disappeared as part of the Ordovician mass extinction event. We enjoy many of those species now only as fossils and if we are lucky, preserved in remarkable detail.

CAPILANO / KIA'PALANO: BEAUTIFUL RIVER

GASTROPODS OF THE COWLITZ FORMATION

A wee block with Eocene marine gastropods from the Coal Creek, Cowlitz Formation just south of Porter near Longview, WA. 

This beautiful site located in a picturesque ravine behind the Jehovah Witness Hall with large maple trees and a slow-moving river boasts wonderful cockles, gastropods & bivalves. 

One sunny afternoon, I took a nap on the bank of that river and was met with the smell of peppery spiciness. Holy Basil had been planted and spread into a wonderful carpet of purple and green aromatic leaves and flowers.

The Cowlitz Formation outcrops hold fossils dating back to the Paleogene. These fossils were discovered in 1911 through the work of Charles E. Weaver, Charles R. Fettkc, Donald Ross, T. A. Bonser, and Olaf Stromme in their work to study the palaeontology of Western Washington. 

Along with the Cowlitz Formation, they also closely observed the Tejon Formation. These two formations are a part of a greater Eocene of Western Washington. The basaltic lavas and tuffs occurring within the Eocene of western Washington have a thickness ranging from fifteen hundred to two thousand feet.

The Cowlitz Formation is located in the canyon of Olequa Creek between the towns of Winlock and Olequa, in southwestern Lewis County, just northwestern Cowlitz County in Washington State.

The rocks composing this formation are sandstones, shales, conglomerates and a subordinate amount of shaly limestone, together with numerous intercalated layers of tuff and basaltic lava. They are partly marine and partly brackish water deposits. As well as the lovely gastropods you see here, there are some very showy bivalves larger than you can wrap your hand around. Tis a worthy site for collecting.

BELEMNITES: INTERNAL CONE STRUCTURE

Lower Jurassic Belemnites, Photo: Georg Laki

Belemnitida is an extinct order of squid-like cephalopods that swam our ancient seas from the Late Triassic to Late Cretaceous. 

Unlike squid, belemnites had an internal skeleton that made up the cone and it is this hard part that we often find fossilized. 

The parts are, from arms to tip: the tongue-shaped pro-ostracum, the conical phragmocone, and the pointy guard.  

When you find these as fossils, it is not intuitive as to what kind of animal they came from. This is the internal hard part of a rather soft, squishy squid-like fellow. 

Because the softer bits are often scavenged and decay, we rarely see them fossilized. Instead, we get what looks like a pointy selection of cigar-shaped goodies that are all that is left of these marine cephalopods. 

We find this fossil in many places around the world. Some friends shared where they have personally found them which I thought might be of interest to you. Arno Martini has found them in northern California, Anne Glenn finds them in Wyoming, Marco Valentin has an enviable collection from Hannover, Misburg, Germany, Juanjo Ugalde Robledo finds them in La Rioja, Spain, Barbara Hnb finds them in Normandy, Patrick Buster finds them in the Navesink Formation of New Jersey, Kim Pervis shared a monograph on Mississippian Belemnites by Rousseau. 

Georg Laki has collected many of their number in the Early Jurassic (Sinemurian/Pliensbachian) of South Luxembourg at Gasperich. I included a photo of Georg's belemnites (with permission) here for you to enjoy. He has a lovely collection that shows the variety of these fossils. 

Anatomy of a Belemnite Fossil

Other notable finds are from Scott Carpenter and his daughter who collect them on the Jurassic Coast, Gabriel Santos who collects them in Peniche, Portugal and Rossi Franco shared a belemnite he found in the building materials used to construct the Bank of Italy in Genoa. 

There are also some wonderfully preserved plates of multiple Jurassic belemnites from Mistelgau, Germany you may want to take a boo at. Imagine slate grey to honey brown Youngibelus and Paxillosus clusters on a beige matrix. Quite stunning. 

I have found them around British Columbia, as has Lloyd Rempel, including at Harrison Lake, British Columbia, Canada. 

SOUTHERN VANCOUVER ISLAND FOSSILS: SOOKE

Stemec suntokum, Sooke Formation

The diving bird you see here is Stemec suntokum, a Fossil Plopterid from Sooke, British Columbia, Canada.

We all dream of finding new species, and new fossil species in particular. This happens more than you think. As impossible as it sounds, it has happened numerous times at many fossils sites in British Columbia including Sooke on Vancouver Island.

The upper Oligocene Sooke Formation outcrops at Muir Beach on southwestern Vancouver Island, British Columbia where it is flanked by the cool, clear waters of the Strait of Juan de Fuca.

While the site has been known since the 1890s, my first trip here was in the early 1990s as part of a Vancouver Paleontological Society (VanPS) fossil field trip. This easy, beach walk locality is a wonderful place to collect fossils and is especially good for families. If you are solar-powered, you will enjoy the sun playing off the surf from May through September. If you are built of hardier stuff, then the drizzle of Spring or Autumn is a lovely, un-people-y time to walk the beachfront.

As well as amazing west coast scenery, the beach site outcrop has a lovely soft matrix with well-preserved fossil molluscs, often with the shell material preserved (Clark and Arnold, 1923).

By the Oligocene ocean temperatures had cooled to near modern levels and the taxa preserved here as fossils bear a strong resemblance to those found living beneath the Strait of Juan de Fuca today. Gastropods, bivalves, echinoids, coral, chitin and limpets are common-ish — and on rare occasions, fossil marine mammals, cetacean and bird bones are discovered.

Fossil Bird Bones 

Back in 2013, Steve Suntok and his family found fossilized bones from a 25-million-year-old wing-propelled flightless diving bird while out strolling the shoreline near Sooke. Not knowing what they had found but recognizing it as significant, the bones were brought to the Royal British Columbia Museum to identify.

The bones found their way into the hands of Gary Kaiser. Kaiser worked as a biologist for Environment Canada and the Nature Conservatory of Canada. After retirement, he turned his eye from our extant avian friends to their fossil lineage. The thing about passion is it never retires. Gary is now a research associate with the Royal British Columbia Museum, published author and continues his research on birds and their paleontological past.

Kaiser identified the well-preserved coracoid bones as the first example from Canada of a Plotopteridae, an extinct family that lived in the North Pacific from the late Eocene to the early Miocene. In honour of the First Nations who have lived in the area since time immemorial and Steve Suntok who found the fossil, Kaiser named the new genus and species Stemec suntokum.

Magellanic Penguin Chick, Spheniscus magellanicus

This is a very special find. Avian fossils from the Sooke Formation are rare. We are especially lucky that the bird bone was fossilized at all.  These are delicate bones and tasty. Scavengers often get to them well before they have a chance and the right conditions to fossilize.

Doubly lucky is that the find was of a coracoid, a bone from the shoulder that provides information on how this bird moved and dove through the water similar to a penguin. It's the wee bit that flexes as the bird moves his wing up and down.

Picture a penguin doing a little waddle and flapping their flipper-like wings getting ready to hop near and dive into the water. Now imagine them expertly porpoising —  gracefully jumping out of the sea and zigzagging through the ocean to avoid predators. It is likely that the Sooke find did some if not all of these activities.

When preservation conditions are kind and we are lucky enough to find the forelimbs of our plotopterid friends, their bones tell us that these water birds used wing-propelled propulsion to move through the water similar to penguins (Hasegawa et al., 1979; Olson and Hasegawa, 1979, 1996; Olson, 1980; Kimura et al., 1998; Mayr, 2005; Sakurai et al., 2008; Dyke et al., 2011).

Kaiser published on the find, along with Junya Watanabe, and Marji Johns. Their work: "A new member of the family Plotopteridae (Aves) from the late Oligocene of British Columbia, Canada," can be found in the November 2015 edition of Palaeontologia Electronica. If you fancy a read, I've included the link below.

The paper shares insights into what we have learned from the coracoid bone from the holotype Stemec suntokum specimen. It has an unusually narrow, conical shaft, much more gracile than the broad, flattened coracoids of other avian groups. This observation has led some to question if it is, in fact, a proto-cormorant of some kind. We'll need to find more of their fossilized lineage to make any additional comparisons.

Sooke, British Columbia and Juan de Fuca Strait

Today, fossils from these flightless birds have been found in outcrops in the United States and Japan (Olson and Hasegawa, 1996). They are bigger than the Sooke specimens, often growing up to two metres.

While we'll never know for sure, the wee fellow from the Sooke Formation was likely about 50-65 cm long and weighed in around 1.72-2.2 kg — so roughly the length of a duck and weight of a small Magellanic Penguin, Spheniscus magellanicus, chick. 

To give you a visual, I have included a photo of one of these cuties here showing off his full range of motion and calling common in so many young.

The first fossil described as a Plotopteridae was from a wee piece of the omal end of a coracoid from Oligocene outcrops of the Pyramid Hill Sand Member, Jewett Sand Formation of California (LACM 8927). Hildegarde Howard (1969) an American avian palaeontologist described it as Plotopterum joaquinensis. Hildegarde also did some fine work in the La Brea Tar Pits, particularly her work on the Rancho La Brea eagles.

In 1894, a portion of a pelagornithid tarsometatarsus, a lower leg bone from Cyphornis magnus (Cope, 1894) was found in Carmanah Group on southwestern Vancouver Island (Wetmore, 1928) and is now in the collections of the National Museum of Canada as P-189401/6323. This is the wee bone we find in the lower leg of birds and some dinosaurs. We also see this same bony feature in our Heterodontosauridae, a family of early and adorably tiny ornithischian dinosaurs — a lovely example of parallel evolution.

While rare, more bird bones have been found in the Sooke Formation over the past decade. In 2013, three avian bones were found in a single year. The first two were identified as possibly being from a cormorant and tentatively identified as Phalacrocoracidae tibiotarsi, the large bone between the femur and the tarsometatarsus in the leg of a bird.

They are now in the collections of the Royal BC Museum as (RBCM.EH2013.033.0001.001 and RBCM.EH2013.035.0001.001). These bones do have the look of our extant cormorant friends but the specimens themselves were not very well-preserved so a positive ID is tricky.

The third (and clearly not last) bone, is a well-preserved coracoid bone now in the collection at the RBCM as (RBCM.EH2014.032.0001.001).

The fossil bird find was the first significant find by the Suntok family but not their last. Just last year, they found part of a fish dental plate was studied by Russian researcher Evgeny Popov who named this new genus and species of prehistoric fish Canadodus suntoki, which translates to the "Tooth from Canada." Perhaps not quite as inspired as Kaiser, but a lovely homage to these Citizen Scientists.

Sooke Fossil Fauna

Along with these rare bird bones, the Paleogene sedimentary deposits of the Carmanah Group on southwestern Vancouver Island have a wonderful diversity of delicate fossil molluscs (Clark and Arnold, 1923). Walking along the beach, look for boulders with white shelly material in them. You'll want to collect from the large fossiliferous blocks and avoid the cliffs. The lines of fossils you see in those cliffs tell the story of deposition along a strandline. Collecting from them is both unsafe and poor form as it disturbs nearby neighbours and is discouraged.

Sooke Formation Gastropods, Photo: John Fam

We find nearshore and intertidal genera such as Mytilus (mussels) and barnacles, as well as more typically subtidal predatory globular moon snails (my personal favourite), surf clams (Spisula, Macoma), and thin, flattened Tellin clams.

The preservation here formed masses of shell coquinas that cemented together but are easily worked with a hammer and chisel. Remember your eye protection and I'd choose wellies or rubber boots over runners or hikers.

You may be especially lucky on your day out. Look for the larger fossil bones of marine mammals and whales that lived along the North American Pacific Coast in the Early Oligocene (Chattian).

Concretions and coquinas on the beach have yielded desmostylid, an extinct herbivorous marine mammal, Cornwallius sookensis (Cornwall, 1922) and 40 cm. skull of a cetacean Chonecetus sookensis (Russell, 1968), and a funnel whale, a primitive ancestor of our Baleen whales. 

A partial lower jaw and molar possibly from a large, bear-like beach-dwelling carnivore, Kolponomos, was also found here. A lovely skull from a specimen of Kolponomos clallamensis (Stirton, 1960) was found 60 km southwest across the Strait of Juan de Fuca in the early Miocene Clallam Formation and published by Lawrence Barnes and James Goedert. That specimen now calls the Natural History Museum of Los Angeles County home and is in their collections as #131148.

Directions to Muir Creek Fossil Site at Sooke: 

From the town of Sooke west of Victoria, follow Highway 14 for about 14 kilometres. Just past the spot where the highway crosses Muir Creek, you will see a gravel parking area on your left. Pull in and park here. 

From the barrier, walk out to the beach and turn right (west) and walk until you see the low yellow-brown sandstone cliffs about 400 metres ahead. 

Look at the grey sandstone boulders on the beach with bits of white flecks in them. The fossil material here will most often be a whitish cream colour. Check for low tide before heading out and choose rubber boots for this beach adventure.

TRACKING DINOSAURS & CROCODILE BONES

This is a theropod track left by an Allosaurus walking through a muddy bank that turned to stone. These big beasties were large carnosaurian theropod dinosaurs that lived 155 to 145 million years ago.

This track and many others are at Dinosaur Ridge, a segment of the Dakota Hogback in the Morrison Fossil Area National Natural Landmark located in Jefferson County, Colorado, near the town of Morrison and just west of Denver.

The Dinosaur Ridge area is one of the world's most famous dinosaur fossil localities. Along with the dinosaur bones, you find plant fossils, crocodile bones and a variety of reptile tracks. 

In 1877, fossil excavation began at Dinosaur Ridge under the direction of palaeontologist Othniel Charles Marsh. Some of the best-known dinosaurs were found here, including Stegosaurus, Apatosaurus, Diplodocus, and Allosaurus. 

In 1973, the area was recognized for its uniqueness as well as its historical and scientific significance when it was designated the Morrison Fossil Area National Natural Landmark by the National Park Service. In 1989, the Friends of Dinosaur Ridge was formed to address increasing concerns regarding the preservation of the site and to offer educational programs on the area's resources.

Visit Dinosaur Ridge Morrison Fossil Area National Natural Landmark

Fancy a trip? You can visit these wonderful tracks, the Dinosaur Ridge Exhibit Hall and walk the trails through the tracks. They have put up helpful interpretive signs that explain the local geology, a volcanic ash bed, trace fossils, paleo-ecology, economic development of coal, oil and clay, and many other geologic and paleontological features.

There are two trails and a visitor centre at Dinosaur Ridge. The visitor centre features information on trails and a small gift shop. If you do not pack a lunch, you'll want to visit the Stegosaurus Snack Shack located outside the visitor centre offering coffee, cold drinks, burritos, pretzels and more. It is open from 10am-4pm Mon-Sat and 11am-4pm on Sun from June through August. 

Check updates on their website concerning Covid-19 restrictions. This is a vast site with easy trails so it makes for a great family trip when museums and other indoor facilities are closed.

HEROES, VILLANS & TYRANTS: HORNBY ISLAND

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.

References: The City of Vancouver Archives has three George Vancouver documents of note:

• The Commission, dated July 10, 1783, appointing him fourth Lieutenant of the HMS Fame (this is the official document confirming a field commission given to him May 7, 1782)
• 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. Vancouver states that they have determined that the Northwest Passage does not exist, which was one of the main goals of his voyage
• A letter to James Sykes written from Vancouver’s home in Petersham, England, after his voyage, October 26, 1797 

DENDRERPETON: CANADA'S EXTINCT AMPHIBIANS

Dendrerpeton acadianum, an extinct amphibian

One of the best Canadian fossil finds stems from a random boulder picked up on the beach near the town of Joggins, Nova Scotia. Inside were the bones of a fully articulated skeleton of Dendrerpeton acadianum, a Temnospondyli from the Lower Pennsylvanian. 

These little cuties belong to an extinct genus of amphibians who loved wet, swampy wetlands similar to those we find in the bayous of Mississippi today.   

Dendrerpeton is the primitive sister-group to a clade of Temnospondyls that includes Trimerorhachoids, the Eryopoids — Ervops, Parioxys, & Sclerocephalus — Zatracheids & Dissorophoids. 

This little guy along with finding the first true reptile, Hylonomus lyelli, ancestor of all dinosaurs that would rule the Earth 100 million years later serve as the reference point where animals finally broke free of the water to live on land. This evolutionary milestone recorded at Joggins remains pivotal to understanding the origins of all vertebrate life on land, including our own species. 

Joggins records life in a once a wet, swampy wetland

Sir Charles Lyell, the author of Principles of Geology, first noted the exceptional natural heritage value of the Joggins Fossil Cliffs. He described them as: 

“...the finest example in the world of a natural exposure in a continuous section ten miles long, occurs in the sea cliffs bordering a branch of the Bay of Fundy in Nova Scotia.” 

Indeed, the world-famous Bay of Fundy with its impressive tides, the highest in the world, and stormy nature exposed much of this outcrop. 

FOSSILS OF CANADA'S EASTER COASTLINE

Hylonomus lyelli, Ancestor of all dinosaurs

The fossil cliffs at Joggins are one of Canada's gems, now a UNESCO World Heritage Site, you can visit to see our ancient world frozen in time. 

Preserved in situ is a snapshot of an entire food chain of a terrestrial Pennsylvanian Coal Age wetland.

The outcrop holds fossil plant life — including impressive standing lycopsid trees that formed the framework of these wetlands — decomposing detritivores in the invertebrates and tetrapods, the predatory carnivores of the day.

The Coal Age trees were fossilized where they stood 300-million-years ago with the remains of the earliest reptiles entombed within. The preservation is quite marvellous with the footprints of creatures who once lived in these wetlands are frozen where they once walked and the dens of amphibians are preserved with remnants of their last meal. 

Nowhere is a record of plant, invertebrate and vertebrate life within now fossilized forests rendered more evocatively. The fossil record at Joggins contains 195+ species of plants, invertebrates and vertebrates. The fossil plant life became the vast coal deposits for which this period of Earth's history is named. 

Recorded in the rock are vertebrate and invertebrate fauna both aquatic and terrestrial. This broad mix of specimens gives us a view into life back in the Pennsylvanian and sets us up to understand their ecological context.

Pennsylvanian Coal Age Ecosystem, 300-Million-Years-Old

The fossil record includes species first defined at Joggins, some of which are found nowhere else on Earth. 

It was here that Sir Charles Lyell, with Sir William Dawson, founder of modern geology, discovered tetrapods — amphibians and reptiles — entombed in the upright fossil trees. 

Later work by Dawson would reveal the first true reptile, Hylonomus lyelli, ancestor of all dinosaurs that would rule the Earth 100 million years later. 

This tiny reptile serves as the reference point where animals finally broke free of the water to live on land. This evolutionary milestone recorded at Joggins remains pivotal to understanding the origins of all vertebrate life on land, including our own species. 

Sir Charles Lyell, author of Principles of Geology, first noted the exceptional natural heritage value of the Joggins Fossil Cliffs, calling them “...the finest example in the world of a natural exposure in a continuous section ten miles long, occurs in the sea cliffs bordering a branch of the Bay of Fundy in Nova Scotia.” Indeed, the world-famous Bay of Fundy with its impressive tides, the highest in the world, and stormy nature exposed much of this outcrop. 

Geological accounts of the celebrated coastal section at Joggins first appear in the published literature in 1828–1829, by Americans C.T. Jackson and F. Alger, and by R. Brown and R. Smith, managers for the General Mining Association in the Sydney and Pictou coal fields. Brown and Smith’s account is the first to document the standing fossil trees.

Plan Your Joggins Fossil Cliffs Staycation

Joggins Fossil Cliffs is a Canadian gem — and they welcome visitors. They offer hands-on learning and discovery microscope activities in their Fossil Lab.

You can explore interpretive displays in the Joggins Fossil Centre before heading out to the beach and cliffs with an interpreter.

Their guided tours of the fossil site include an educational component that tells you about the geology, ecology, palaeontology and conservation of this very special site. 

Joggins / Chegoggin / Mi'kmaq L'nu

We know this area as Joggins today. In Mi'kmaw, the language spoken in Mi'kma'ki, the territory of the Mi'kmaq L'nu, the area bears another name, Chegoggin, place of fishing weirs.

Booking Your Class Field Trip

If you are a teacher and would like to book a class field trip, contact the Director of Operations via the contact information listed below. They will walk you through Covid safety and discuss how to make your visit educational, memorable and fun.

Know Before You Go

The Bay of Fundy has the highest tides in the world. Beach walks are scheduled according to the tides and run regardless of the weather. Good low tides but raining, the beach walk goes on. Lovely and sunny but with a high tide, the beach walk must wait. So, you will want to dress for it as they will not be cancelled in the event of rain. Should severe weather be a factor, bookings may need to be rescheduled at the discretion of the Joggins staff.

Any questions about booking your school field trip? Feel free to email:  operations@jogginsfossilcliffs.net or call: 1 (902) 251-2727 EXT 222.
