BC'S FOSSIL BOUNTY — CONSERVATION THROUGH PALAEOART: JULIUS CSOTONYI
Julius Csotonyi BTS on BC'S FOSSIL BOUNTY |
He got hooked on the palaeontology bug early and has been doodling dinosaurs since childhood.
Over the years, he has expanded his portfolio to include all branches of scientifically inspired artwork — each of them beautifully rendered.
He has collaborated on projects with several major museums and book publishers from around the globe, including the National Geographic Society and the Royal Tyrrell Museum, working closely with scientists and drawing from his scientific background.
An MSc graduate of Ecology and Environmental Biology (University of Alberta), and a PhD graduate in microbiology (University of Manitoba), he has published scientific papers on mutualisms in Utah and some very cool and unusual alien-looking bacteria from deep ocean hydrothermal volcanic vents.
His scientific background fuels his passion to strive to restore as realistically as possible the curiously alien environments that earth has hosted in its deep past.
His style spans the gamut from pencil and ink line drawings to watercolour, pastel, 2-dimensional digital illustrations and 3-dimensional digital models. His superbly detailed work encompasses dinosaurs and other prehistoric life, sharks and other living animals, as well as space art, fantasy and science fiction themes.
Julius Csotonyi's Hell Creek Raptor |
His largest projects to date have been a panoramic 75-foot-long mural commissioned for the Houston Museum of Natural Science (HMNS), depicting a Late Cretaceous Montana ecosystem along with a mummified Brachylophosaurus — Dinosaur Mummy CSI: Cretaceous Science Investigation, 2008.
He has illustrated many life-sized dinosaur murals — some up to 45 metres or 150 feet long — for the Royal Ontario Museum's 2012 exhibit, Ultimate Dinosaurs; Giants from Gondwana.
Julius illustrated the 25th anniversary exhibit ('Alberta Unearthed') for the Royal Tyrrell Museum of Paleontology (Drumheller, Alberta, 2010) and most of the new Hall of Paleontology at the HMNS.
Some of his other projects have included the ceratopsian exhibit for the Royal Tyrrell Museum (2007), a mummified Edmontosaurus for Phillip Manning's 'Grave Secrets of Dinosaurs' (National Geographic Books, 2007) and an African Massospondylus nesting site (Royal Ontario Museum, Toronto, 2010). In addition to books and museum projects,
Csotonyi accepts private commissions of artwork in a wide range of digital and traditional media. His website, http://csotonyi.com, features a growing portfolio of his work, and some of it is also featured on his science blog, 'Evolutionary Routes'.
He is appearing in BC'S FOSSIL BOUNTY — airing on TELUS Optik TV & the TELUS YouTube Channel beginning Autumn 2022.

URSIDAE: URSAVUS
Both bear families descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage given the size of their very large descendants.
An average Grizzly weighs in around 800 lbs (363 kg), but a recent find in Alaska tops the charts at 1600 lbs (726 kg).
This mighty beast stood 12' 6' high at the shoulder, 14' to the top of his head and is one of the largest grizzlies ever recorded. This past September, the King of the forest was seen once again in the Washington Cascades -- the first sighting in over 50 years.
Grizzly Bears in First Nation Lore and Language
In the Kwak'wala language of the Kwakiutl First Nations of the Pacific Northwest — or Kwakwaka'wakw, speakers of Kwak'wala — a grizzly bear is known as na̱n and the ornamental grizzly bear headdress worn by the comic Dluwalakha grizzly bear dancers in the Grizzly Bear Dance, Gaga̱lalał, is known as na̱ng̱a̱mł.
There is another grizzly bear who features in the Hamatsa dance, known as Nanes Bakbakwalanooksiwae, a high-ranking figure who has no mask — instead, the dancers paint their faces dark red to symbolize a hungry bear mouth and dance in costumes made of bearskin with terrifying long wooden claws.

LOVE CAN TRAVEL ANYWHERE IN AN INSTANT
Nunatsiarmiut Mother and Child, Baffin Island, Nunavut |
As part of the Qikiqtaaluk Region of Nunavut, Baffin Island is home to a constellation of remote Inuit communities each with a deep cultural connection to the land — Iqaluit, Pond Inlet, Pangnirtung, Clyde River, Arctic Bay, Kimmirut and Nanisivik.
The ratio of Inuit to non-Inuit here is roughly three to one and perhaps the reason why the Inuktitut language has remained intact and serves as the mother tongue for more than 36,000 residents. Inuktitut has several subdialects — these, along with a myriad of other languages — are spoken across the north.
If you look at the helpful visual below you begin to get a feel for the diversity of these many tongues. The languages vary by region. There is the Iñupiaq of the Inupiatun/Inupiat; Inuvialuktun of the Inuinnaqtun, Natsilingmiutut, Kivallirmiutut, Aivilingmiutut, Qikiqtaaluk Uannanganii and Siglitun. Kalaallisut is spoken by many Greenlandic peoples though, in northwest Greenland, Inuktun is the language of the Inughuit.
We use the word Inuktitut when referring to a specific dialect and inuktut when referring to all the dialects of Inuktitut and Inuinnaqtun.
Northern Language Map (Click to Enlarge) |
The word for hello or welcome in Inuktitut is Atelihai — pronounced ahh-tee-lee-hi. And thank you is nakurmiik, pronounced na-kur-MIIK.
Perhaps my favourite Inuktitut expression is Naglingniq qaikautigijunnaqtuq maannakautigi, pronounced NAG-ling-niq QAI-kau-ti-gi-jun-naqtuq MAAN-na-KAU-ti-gi. This tongue-twister is well worth the linguistic challenge as it translates to love can travel anywhere in an instant. Indeed it can.
You have likely seen or heard the word Eskimo used in older books to refer to the Inuit, Iñupiat, Kalaallit or Yupik. This misnomer is a colonial term derived from the Montagnais or Innu word ayas̆kimew — netter of snowshoes. It is a bit like meeting a whole new group of people who happen to wear shoes and referring to them all as cobblers — not as a nickname, but as a legal term to describe populations from diverse communities disregarding the way each self-refer.
Inukshuk / Inuksuk Marker Cairn |
The Inuit of Greenland self-refer as Kalaallit or Greenlanders when speaking Kalaallisut. The Inupiat of Alaska, or real people, use Yupik as the singular for real person and yuk to simply mean person.
When taken all together, Inuit is used to mean all the peoples in reference to the Inuit, Iñupiat, Kalaallit and Yupik. Inuit is the plural of inuk or person.
You likely recognize this word from inuksuk or inukshuk, pronounced ih-nook-suuk — the human-shaped stone cairns built by the Inuit, Iñupiat, Kalaallit, Yupik, and other peoples of the Arctic regions of northern Canada, Greenland, and Alaska — helpful reference markers for hunters and navigation. The word inuksuk means that which acts in the capacity of a human, combining inuk or person and suk, to substitute.
A World of Confusion
You may be disappointed to learn that our northern friends do not live in igloos. I remember answering the phone as a child and the fellow calling was hoping to speak to my parents about some wonderful new invention perfect for use in an igloo. He was disappointed to hear that I was standing in a wooden house with the standard four walls to a room and a handy roof topping it off. "Well, what about your neighbours? Surely some of them live in igloos..." It seems that some of the atlases in circulation at the time, and certainly the one he was looking at, simply blanketed everything north of the 49th parallel in a snowy white. His clearly showed an igloo sitting proudly in the centre of the province.
My cousin Shawn brought one such simplified book back from his elementary school in California. British Columbia had a nice image of a grizzly bear and a wee bit further up, a polar bear grinned smugly. British Columbia's beaver population would be sad to know that they did not inhabit the province though there were two chipper beavers with big bright smiles — one in Ontario and another gracing the province of Quebec. Further north, where folk do build igloos, they were curiously lacking.
Igloos are used for winter hunting trips much the same way we use tents for camping. The Inuit do not have fifty words for snow — you can thank the ethnographer Franz Boas for that wee fabrication — but within the collective languages of the frozen north there are more than fifty words to describe it. And kisses are not nose-to-nose. To give a tender kiss or kunik to a loved one, you press your nose and upper lip to their forehead or cheek and rub gently.
Fancy to try a wee bit of Inuktitut yourself? This link will bring you to a great place to start: https://inhabitmedia.com/inuitnipingit/

PORPOISE: K'ULUT'A
Dall's Porpoise |
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.
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.

BC'S FOSSIL BOUNTY: KAY LILLICO, DINOSAUR DOCENT
Behind the Scenes on BC'S FOSSIL BOUNTY |
Kay delivered pure gold on her work sharing the science of palaeontology.
We learned how Kay’s passion for dinosaurs (sexy little raptors) & invertebrates including the arthropod Anomalocaris led her to become a Science Communicator & pursue her dreams at Dino Lab Inc. — and how you can, too!
Kay encourages everyone who is excited by the prospect of palaeontology to keep pursuing knowledge and go after their dreams! Seek out opportunities, really don’t be afraid to get outside of your comfort zone. Her path led her to work at Dino Lab Inc. — an awesome hand's on museum that does educational tours, fossil prep and has real fossils you can visit in person.
Ever pet a Triceratops? You can at Dino Lab! They are the originators of the hands on dinosaur experience. If you head on over for a tour be sure to check out their Fossil Restoration Lab, Fossil Gallery and palaeontology themed gift shop.
Behind the Scenes on BC'S FOSSIL BOUNTY |
Vancouver is a magical place. We live in a diverse province edged by mountains, ocean, forests and streams. While our lens is often on the rugged beauty all around us, beneath our feet is yet another world.
Layers of rock hold fossils, each an interface to our deep past. Within each fragment, these ancient beings whisper their secrets, share their life experiences, tell us tales of community, how they made a living, who they rubbed shoulders with (or fins, or seedlings...) and convey the essence of a world long embedded in stone.
Join me as we explore the rich fossil bounty of fossil plants, dinosaurs to mighty marine reptiles and the people who unearth them.
Discover British Columbia's violent past — how plate tectonics, volcanoes and glaciers shaped the land and why we find plant fossils along the Kitsilano foreshore and marine fossils beneath False Creek. Did you know that some female dinosaurs have distinctive bone material that tells us they are just about to give birth or just became new mammas? You will once you see Kay Lillico's episode on Season One of BC's Fossil Bounty.
Hear from palaeontologists, geologists, geochemists, science organizations, dinosaur docents, palaeoartists and fossil preparators whose work brings our ancient world to life.

CAPILANO RIVER: STONE, BONE & WATER
Cretaceous Plant Material / Three Brothers Formation |
If you were standing on the top of the Lion's Gate Bridge looking north you would see the Capilano Reservoir is tucked in between the Lions to the west and Mount Seymour to the east on the North Shore.
The Capilano River on Vancouver's North Shore flows through the Coast Mountains and our coastal rainforest down to the Capilano watershed enroute to Burrard Inlet. The headwaters are at the top of Capilano up near Furry Creek. They flow down through the valley, adding in rainwater, snowmelt and many tributaries before flowing into Capilano Lake. The lake in turn flows through Capilano Canyon and feeds into the Capilano River.
We have Ernest Albert Cleveland to thank for the loss of that salmon but can credit him with much of our drinking water as it is caught and stored by the dam that bears his name. It was his vision to capture the bounty from the watershed and ensure it made its way into our cups and not the sea.
Capilano River Canyon & Regional Park |
There are Cretaceous fossils found only in the sandstone. You will see exposed shale in the area but it does not contain fossil material.
Capilano Fossil Field Trip:
From Clyde Avenue walk down the path to your left towards the Capilano River. Watch the water level and tread cautiously as it can be slippery if there has been any recent rain. Look for beds of sandstone about 200 meters north of the private bridge and just south of the Highway bridge. The fossil beds are just below the Whytecliff Apartment high rises. Be mindful of high water and slippery rocks.

STANLEY PARK: LIVED HISTORY
Totem, Welcome & Mortuary Poles at Stanley Park |
What you are viewing are replicas of First Nation welcome and totem poles that once stood in the park but have been returned to their homes within the province's diverse First Nation communities — or held within museum collections.
Some of the original totems came from Alert Bay on Cormorant Island, near the Port McNeill on the north coast of Vancouver Island.
Others came from communities in Haida Gwaii — and still more from the Wuikinuxv First Nations at Rivers Inlet on British Columbia's central west coast — home of the Great Bear Rainforest with her Spirit Bears.
The exception is the most recent addition carved by Robert Yelton in 2009. Robert is a First Nation carver from the Squamish Nation and his original welcome pole graces Brockton Point, the original settlement site of a group of Squamish-Portuguese settlers.
If you look at the photo above, the lovely chocolate, red and turquoise pole on the right is a replica of the mortuary pole raised to honour the Raven Chief of Skedans or Gida'nsta, the Haida phrase for from his daughter, the title of respect used when addressing a person of high rank. Early fur traders often took the name of the local Chief and used it synonymously as the place names for the sites they visited — hence Skedans from Gida'nsta.
Chief Skedans Mortuary Pole |
Upon Chief Skedan's death, the mortuary pole was carved both to honour him and provide his final resting place. Dates are a bit fuzzy, but local accounts have this as sometime between 1870-1878 — and at a cost of 290 blankets or roughly $600 in today's currency.
The great artistry of the pole was much admired by those in the community and those organizing the celebrations for the 1936 Vancouver Golden Jubilee — witnessed by 350,000 newly arrived residents.
Negotiations were pursued and the pole made its way down from Haida Gwaii to Stanley Park in time for the celebrations. The original totem graced Stanley Park for a little over twenty years before eventually making its way back to Haida Gwaii. It was returned to the community with bits of plaster and shoddy paint marring the original. These bits were scraped off and the pole welcomed back with due ceremony.
In 1964, respected and renowned Northwest Coast master carver, Bill Reid, from the Kaadaas gaah Kiiguwaay, Raven/Wolf Clan of T'anuu, Haida Gwaii and Scottish-German descent, was asked to carve this colourful replica.
Mountain Goat Detail, Skedans Mortuary Pole |
Don Yeomans, Haida master carver, meticulously recarved the moon crest in 1998. If you have admired the totem pole in the Vancouver Airport, you will have seen some of Yeoman's incredible work.
The crest is Moon with the face, wings, legs and claws of a mighty and proud Thunderbird with a fairly smallish hooked beak in a split design. We have Moon to thank for the tides and illuminating our darkest nights. As a crest, Moon is associated with transformation and acting as both guardian and protector.
The original pole had a mortuary box that held the Chief's remains. The crest sits atop a very charming mountain goat. I have included a nice close-up here of the replica for you to enjoy.
Mountain Goats live in the high peaks of British Columbia and being so close to the sky, they have the supernatural ability to cross over to the sky world. They are also credited as being spirit guardians and guides to First Nation shamans.
I love his horns and tucked in cloven hooves. There is another pole being carved on Vancouver Island that I hope to see during its creation that also depicts a Mountain Goat. With permission and in time, I hope to share some of those photos with you.
Mountain Goat is sitting atop Grizzly Bear or Huaji or Xhuwaji’ with little human figures placed in his ears to represent the Chief's daughter and son-in-law, who raised the pole and held a potlatch in his honour.
Beneath the great bear is Seal or Killer Whale in his grasp. The inscription in the park says it is a Killer Whale but I am not sure about that interpretation — both the look and lore make Seal more likely. Perhaps if Killer Whale were within Thunderbird's grasp — maybe.
Though it is always a pleasure to see Killer Whale carved in red cedar, as the first whales came into being when they were carved in wood by a human — or by Raven — then magically infused with the gift of life. We think of totem pole as being part of the material culture of all Indigenous cultures across Canada when, indeed, they are carved by only a few and not always in the ways that you expect.
Some are welcome poles, others record the loss of a loved one in a mortuary pole, some have spread wings like those carved by the Kwakwaka'wakw.Some are house fronts or house posts, others are shaped like an entryway versus the tall thin poles you might expect.
We can thank the talented artists of the Haida, Nuxalk, Kwakwaka'wakw, Tlingit, Tsimshian and Coast Salish for the poles we enjoy in the Pacific Northwest.
It is their storytelling and clan crests that we are enjoying when we look upon these carvings. These are the stories of their ancestors, their heroics, challenges, titles, deeds and sorrow. Each a masterpiece as a visual that supports an oral tradition—stories told and reinforced year-upon-year at Winter ceremonies.
Siwash Rock on the northern end of Third Beach, Stanley Park |
Glacial deposits sit atop as a mix of clay, sand, cobbles and larger boulders of glacial till.
There are a few areas of exposed volcanics within the park that speak to the scraping of the glaciers as they retreated about 12,500 years ago.
The iconic moss and lichen coated Siwash Rock on the northern end of Third Beach is one of the more picturesque of these. It is a basaltic and andesitic volcanic rock — a blend of black phenocrysts of augite cemented together with plagioclase, hornblende and volcanic glass.

A REPTILE IN THE SKY: DIMORPHODON
You can see this fellow's interesting teeth within his big, bulky skull. Dimorphodon had two distinct types of teeth in their jaws — an oddity amongst reptiles — and also proportionally short wings for their overall size.
Just look at him. What an amazing beast. We understand their anatomy quite well today, but can you imagine being the first to study their fossils and try to make sense of them.
The first fossil remains now attributed to Dimorphodon were found in England by fossil collector Mary Anning, at Lyme Regis in Dorset, the United Kingdom in December 1828. While she faced many challenges in her life, she was blessed to live in one of the richest areas in Britain for finding fossils.
She walked the beaches way back in the early 1800s of what would become the Jurassic Coast UNESCO World Heritage Site. The Jurassic Coast holds some of the most interesting fossils ever found — particularly within the strata of the Blue Lias which date back to the Hettangian-Sinemurian. It is one of the world’s most famous fossil sites. Millions come to explore the eroding coastline looking for treasures that provide delight and inspiration to young and old.
These fossil treasures provide us with tremendous insights into our world 185 million years ago when amazing animals like Dimorphodon ruled the skies.
Mary's specimen was acquired by William Buckland and reported in a meeting of the Geological Society on 5 February 1829. Six years later, in 1835, William Clift and William John Broderip built upon the work by Buckland to publish in the Transactions of the Geological Society, describing and naming the fossil as a new species.
As was the case with most early pterosaur finds, Buckland classified the remains in the genus Pterodactylus, coining the new species Pterodactylus macronyx. The specific name is derived from Greek makros, "large" and onyx, "claw", in reference to the large claws of the hand. The specimen, presently NHMUK PV R 1034, consisted of a partial and disarticulated skeleton on a slab — notably lacking the skull. Buckland in 1835 also assigned a piece of the jaw from the collection of Elizabeth Philpot to P. macronyx.
Later, the many putative species assigned to Pterodactylus had become so anatomically diverse that they began to be broken into separate genera.
In 1858, Richard Owen reported finding two new specimens, NHMUK PV OR 41212 and NHMUK PV R 1035, again partial skeletons but this time including the skulls. Having found the skull to be very different from that of Pterodactylus, Owen assigned Pterodactylus macronyx its own genus, which he named Dimorphodon.
His first report contained no description and the name remained a nomen nudum. In 1859, however, a subsequent publication by Owen provided a description. After several studies highlighting aspects of Dimorphodon's anatomy, Owen finally made NHMUK PV R 1034 the holotype in 1874 — 185 million years after cruising our skies the Dimorphodon had finally fully arrived.

CHIEF MUNGO MARTIN OF GILFORD ISLAND
Mungo Martin was born in 1879 in Tsaxis, Fort Rupert, on northern Vancouver Island, British Columbia, Canada, where I grew up.
He was the son of Yaxnukwelas, a high-ranking First Nation Kwakiutl from Gilford Island. His mother was Q'omiga, also known by her English name, Sarah Finlay, who was the daughter of a Kwakwaka'wakw woman and a Scottish man working with the Hudson's Bay Company.
Martin's father died when he was in his teen years. His mother married Yakuglas, also known in English as Charlie James. Martin's mother wanted her son to become a woodcarver and song maker, and held rituals to ensure this future
While still young, Martin regularly participated in the rituals, songs, arts, and traditions of the local Kwakwaka'wakw and North Coastal culture. This formed the basis of his knowledge of the Northwest Coast style, and he applied it to design, carving, and painting and lifelong song making. Martin was raised in the potlatch tradition practiced by the Kwakwaka'wakw, and all aspects of their culture.
As a boy Martin had been apprenticed as a carver to a paternal uncle. His stepfather Charlie James, a noted Northwestern artist, was his principal influence in honing his natural talent. Martin developed as one of the first traditional artists to adopt many types of Northwest Coast sculptural and painting styles.
He carved his first commissioned totem pole in 'ya̱lis (Alert Bay) c1900, and titled it "Raven of the Sea." Martin also restored and repaired many carvings and sculptures, totem poles, masks, and various other ceremonial objects. He gained fame for holding the first public potlatch since the governmental potlatch ban of 1885.
He was awarded with a medal by the Canadian Council. In 1947, Martin was hired by the Museum of Anthropology at UBC for restoration and replica work.
During this time, Martin lived on the university campus, and continued to paint and carve small works during the night. Gwaxwiwe' hamsiwe' (mask of the raven man-eater) by Mungo Martin at the Seattle Art Museum Later, Martin was hired in 1952 by the Royal British Columbia Museum in Victoria, British Columbia to create works of Northwest Coastal Art as display pieces and examples. The final result was a huge totem pole, carved out of cedar, standing 160 feet tall. It was raised in 1956 and remained standing until 2000.
He constructed Wawadit'la, a Kwakwaka'wakw "big house", at Thunderbird Park in front of the museum. During this time he and American anthropologist Bill Holm became fast friends and Martin designed a Kwak'waka'wakw big house on the coast in Washington State.
Martin was the designer and principal carver of the famous Totem Pole in Windsor Great Park in the United Kingdom. The Totem Pole was a gift from the people of Canada to HM The Queen in June, 1958. Standing 100 feet high, there is one foot for every year, and marks the centenary of British Columbia, which was named by Queen Victoria and proclaimed a Crown Colony on November 19, 1858. It is now the Pacific Coast Province of Canada.
The figures on the pole reading from the top are, Man with large hat, Beaver, Old Man, Thunderbird, Sea Otter, The Raven, The Whale, Double headed Snake, Halibut Man and Cedar Man. Each figure represents the mythical ancestor of a clan. The pole was carved from a single log of Western Red Cedar and weighs 27,000 pounds. It was cut from a tree 600 years old from the forests of the Queen Charlotte Islands, 500 miles north of Vancouver.
When Martin went to work for the museum in Victoria, his son David and his family, and relatives Henry and Helen Hunt (Helen was Martin's wife's granddaughter) and their family joined him in living in James Bay near Thunderbird Park and the focus of the work to be done.
His son David, and Henry Hunt, and even Henry's son Tony who was only twelve when the families engaged in this undertaking, became apprentices. Martin trained his son David in his craft but David died in 1959. Henry's sons Stanley Hunt and Richard Hunt are also professional carvers.
Note: House built by Mungo Martin and David Martin with carpenter Robert J. Wallace. Based on Chief Nakap'ankam's house in Tsaxis (Fort Rupert). The house "bears on its house-posts the hereditary crests of Martin's family." It continues to be used for ceremonies with the permission of Chief Oast'akalagalis 'Walas 'Namugwis (Peter Knox, Martin's grandson) and Mable Knox. Pole carved by Mungo Martin, David Martin and Mildred Hunt. "Rather than display his own crests on the pole, which was customary, Martin chose to include crests representing the A'wa'etlala, Kwagu'l, 'Nak'waxda'xw and 'Namgis Nations. In this way, the pole represents and honours all the Kwakwaka'wakw people."

APODOCERAS: SEXUAL DIMORPHISM
Apodoceras / Stonebarrow Fossils |
Apoderoceras has been found in the Lower Jurassic of Argentina, Hungary, Italy, Portugal, and most of North-West and central Europe, including as this one is, the United Kingdom. This specimen was found on the beaches of Charmouth in West Dorset.
Neither Apoderoceras nor Bifericeras donovani are strictly index fossils for the Taylori subzone, the index being Phricodoceras taylori. Note that Bifericeras is typical of the earlier Oxynotum Zone, and ‘Bifericeras’ donovani is doubtfully attributable to the genus. The International Commission on Stratigraphy (ICS) has assigned the First Appearance Datum of genus Apoderoceras and of Bifericeras donovani the defining biological marker for the start of the Pliensbachian Stage of the Jurassic, 190.8 ± 1.0 million years ago.
Apoderoceras, Family Coeloceratidae, appears out of nowhere in the basal Pliensbachian and dominates the ammonite faunas of NW Europe. It is superficially similar to the earlier Eteoderoceras, Family Eoderoceratidae, of the Raricostatum Zone, but on close inspection can be seen to be quite different. It is therefore an ‘invader’ and its ancestry is cryptic.
The Pacific ammonite Andicoeloceras, known from Chile, appears quite closely related and may be ancestral, but the time correlation of Pacific and NW European ammonite faunas is challenging. Even if Andicoeloceras is ancestral to Apoderoceras, no other preceding ammonites attributable to Coeloceratidae are known. We may yet find clues in the Lias of Canada. Apoderoceras remains present in NW Europe throughout the Taylori Subzone, showing endemic evolution. It becomes progressively more inflated during this interval of time, the adult ribs more distant, and there is evidence that the diameter of the macroconch evolved to become larger. At the end of the Taylori Subzone, Apoderoceras disappeared as suddenly as it appeared in the region, and ammonite faunas of the remaining Jamesoni Zone are dominated by the Platypleuroceras–Uptonia lineage, generally assigned (though erroneously) to the Family Polymorphitidae.
In the NW European Taylori Subzone, Apoderoceras is accompanied (as well as by the Eoderoceratid, B. donovani, which is only documented from the Yorkshire coast, although there are known examples from Northern Ireland) by the oxycones Radstockiceras (quite common) and Oxynoticeras (very rare), the late Schlotheimid, Phricoderoceras (uncommon) Note: P. taylori is a microconch, and P. lamellosum, the macroconch), and the Eoderoceratid, Tetraspidoceras (very rare). The lovely large specimen (macroconch) of Apoderoceras pictured here is likely a female. Her larger body perfected for egg production.

ETHELDRED BENETT: CITIZEN SCIENTIST
Hoplites (Hoplites) bennettiana (Sowerby, 1826) |
The species name is a homage to Etheldred Benett, an early English geologist often credited with being the first female geologist — a fossil collector par excellence.
She was also credited with being a man — the Natural History Society of Moscow awarding her membership as Master Etheldredus Benett in 1836.
The Tsar had read Sowerby's Mineral Conchology, a major fossil reference work that contained the second-highest number of contributed fossils of the day, many of them with the best preservation seen at that time. Forty-one of those specimens were credited to Benett. Between her name and this wonderous contribution to a growing science, the Russian Tsar awarded the Doctorate to what he believed was a young male scientist on the rise.
Benett took these honours (and social blunders) with grace. She devoted her life to collecting and studying fossils from the southwest of England, amassing an impressive personal collection she openly shared with geologist friends, colleagues and visitors to her home. Her speciality was fossils from the Middle Cretaceous, Upper Greensand in the Vale of Wardour — a valley in the county of Wiltshire near the River Nadder.
Etheldred was a local Wiltshire girl. Born Etheldred Benett on 22 July 1775 at Pyt House, Tisbury, Wiltshire, the eldest daughter of the local squire Thomas Benett. Etheldred's interest was cultivated by the botanist Aylmer Bourke Lambert (1761-1842), a founding member of the Linnean Society. Benett's brother had married Lucy Lambert, Aylmer's half-sister. Aylmer was a Fellow of the Royal Society and the Society of the Arts. He was also an avid fossil collector and member of the Geological Society of London. The two met and got on famously.
Aylmer kindled an interest in natural history in both of Benett's daughters. Etheldred had a great fondness for geology, stratigraphy and all things paleo, whilst her sister concentrated on botany. Etheldred had a distinct advantage over her near contemporary, the working-class Mary Anning (1799-1847), in that Benett was a woman of independent wealth who never married — and didn't need to — who could pursue the acquisition and study of fossils for her own interest.
While Anning was the marine reptile darling of the age, she was also greatly hindered by her finances. "She sells, seashells by the seashore..." while chanted in a playful spirit today, was not meant kindly at the time. Aylmer's encouragement emboldened Etheldred to go into the field to collect for herself — and collect she did. Profusely.
Benett’s contribution to the early history of Wiltshire geology is significant. She corresponded extensively with the coterie of gentlemen scientists of the day — Gideon Mantell, William Buckland, James Sowerby, George Bellas Greenough and, Samuel Woodward. She also consorted with the lay folk and had an ongoing correspondence with William Smith, whose stratigraphy work had made a favourable impression on her brother-in-law, Aylmer.
Her collections and collaboration with geologists of the day were instrumental in helping to form the field of geology as a science. One colleague and friend, Gideon Mantell, British physician, geologist and palaeontologist, who discovered four of the five genera of dinosaurs and Iguanadon, was so inspired by Benett's work he named this Cretaceous ammonite after her — Hoplites bennettiana.
Benett's fossil assemblage was a valuable resource for her contemporaries and remains so today. It contains thousands of Jurassic and Cretaceous fossil specimens from the Wiltshire area and the Dorset Coast, including a myriad of first recorded finds. The scientific name of every taxon is usually based on one particular specimen, or in some cases multiple specimens. Many of the specimens she collected serve as the Type Specimen for new species.

Alas, no one took up the helm — those interested were busy with other pursuits (or passed away) and others were less than enthusiastic or never seemed to get around to it.
To ensure the knowledge was shared in a timely fashion, she finally wrote them up and published them herself. You can read her findings in her publication, ‘A Catalogue of Organic Remains of the County of Wiltshire’ (1831), where she shares observations on the fossil sponge specimens and other invert goodies from the outcrops west of town.
She shared her ideas freely and donated many specimens to local museums. It was through her exchange of observations, new ideas and open sharing of fossils with Gideon Mantell and others that a clearer understanding of the Lower Cretaceous sedimentary rocks of Southern England was gained.
In many ways, Mantell was drawn to Benett as his ideas went against the majority opinion. At a time when marine reptiles were dominating scientific discoveries and discussions, he pushed the view that dinosaurs were terrestrial, not amphibious, and sometimes bipedal. Mantell's life's work established the now-familiar idea that the Age of Reptiles preceded the Age of Mammals. Mantell kept a journal from 1819-1852, that remained unpublished until 1940 when E. Cecil Curwen published an abridged version. (Oxford University Press 1940). John A. Cooper, Royal Pavilion and Museums, Brighton and Hove, published the work in its entirety in 2010.
I was elated to get a copy, both to untangle the history of the time and to better learn about the relationship between Mantell and Benett. So much of our geologic past has been revealed since Mantell's first entry two hundred years ago. The first encounter we share with the two of them is a short note from March 8, 1819. "This morning I received a letter from Miss Bennett of Norton House near Warminster Wilts, informing me of her having sent a packet of fossils for me, to the Waggon Office..." The diary records his life, but also the social interactions of the day and the small connected community of the scientific social elite. It is a delight!
Though a woman in a newly evolving field, her work, dedication and ideas were recognized and appreciated by her colleagues. Gideon Mantell described her as, "a lady of great talent and indefatigable research," whilst the Sowerbys noted her, "labours in the pursuit of geological information have been as useful as they have been incessant."
Benett produced the first measured sections of the Upper Chicksgrove quarry near Tisbury in 1819, published and shared with local colleagues as, "the measure of different beds of stone in Chicksgrove Quarry in the Parish of Tisbury.” The stratigraphic section was later published by naturalist James Sowerby without her knowledge. Her research contradicted many of Sowerby’s conclusions.
She wrote and privately published a monograph in 1831, containing many of her drawings and sketches of molluscs and sponges. Her work included sketches of fossil Alcyonia (1816) from the Green Sand Formation at Warminster Common and the immediate vicinity of Warminster in Wiltshire.
Echinoids and Bivalves. Collection of Etheldred Benett (1775-1845) |
If you'd like to read a lovely tale on William's work, check out the Map that Changed the World: William Smith and the Birth of Modern Geology by Simon Winchester. It narrates the intellectual context of the time, the development of Smith's ideas and how they contributed to the theory of evolution and more generally to a dawning realization of the true age of the earth.
The book describes the social, economic or industrial context for Smith's insights and work, such as the importance of coal mining and the transport of coal by means of canals, both of which were a stimulus to the study of geology and the means whereby Smith supported his research. Benett debated many of the ideas Smith put forward. She was luckier than Smith financially, coming from a wealthy family, a financial perk that allowed her the freedom to add fossils to her curiosity cabinet at will.
Most of her impressive collection was assumed lost in the early 20th century. It was later found and purchased by an American, Thomas Bellerby Wilson, who donated it to the Academy of Natural Sciences of Philadelphia. Small parts of it made their way into British museums, including the Leeds City Museum, London, Bristol and the University of St. Petersburg. These collections contain many of the Type specimens and some of the very first fossils found — some with the soft tissues preserved. When Benett died in 1845, it was Mantell who penned her obituary for the London Geological Journal.
In 1989, almost a hundred and fifty years after her death, a review of her collection had Arthur Bogen and Hugh Torrens remark that her work has significantly impacted our modern understanding of Porifera, Coelenterata, Echinodermata, and the molluscan classes, Cephalopoda, Gastropoda, and Bivalvia. A worthy legacy, indeed.
Her renown lives on through her collections, her collaborations and through the beautiful 110 million-year-old ammonite you see here, Hoplites bennettiana. The lovely example you see here is in the collection of the deeply awesome Christophe Marot.

FOSSILS OF SOUTHERN VANCOUVER ISLAND: SOOKE
Stemec suntokum, Sooke Formation |
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 |
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 |
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.
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.
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).
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.

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.
