On today's show, you'll hear about a paper delivered on a chilly December evening in 1857 by Philip Sclater that hugely inspired Alfred Wallace and eventually led to the publication of the Origin of Species by Charles Darwin. Both Sclater and Wallace were extraordinary in their own right. Both were passionate about natural history, keen observers of our natural world, world travellers and gracious in their gifts to the world. Season Eleven, Episode 106…

In this episode, you'll hear about some wonderful free Zoom Fossil Talks in March and May 2024. There is no need to register. You can head on over to www.fossiltalksandfieldtrips.com and note the talk dates and times. The link will be shared live on the site on the day of the talk. Upcoming Free Fossil Lectures via Zoom: Sun, March 24, 2024, 2PM PST — Dan Bowen — Struck by Lightning: The Mary Anning Story Learn about the history of Mary Anning from Dan Bowen, Chair of the Vancouver Island Palaeontological Society (VIPS) and British Columbia Palaeontological Alliance (BCPA). Mary Anning was an English fossil collector, dealer, and palaeontologist who became known worldwide for her discoveries in Jurassic marine fossil beds in the cliffs along the English Channel at Lyme Regis in the county of Dorset in Southwest England. Sat, May 4, 2024, 1PM PST — Jean-Bernard Caron, Lower Cambrian Cranbrook Lagerstätte in the East Kootenay region of south-eastern British Columbia, Canada Jean-Bernard Caron is a French and Canadian palaeontologist and curator of invertebrate palaeontology at the Royal Ontario Museum in Toronto, Ontario, Canada. He will share his insights on the weird and wonderful marine fossil fauna from the many outcrops of the Lower Cambrian Eager Formation near the town of Cranbrook. His team did some extensive field work—particularly at the Silhouette Range locality—a few summers ago and we are keen to hear the results of their efforts. The fossils we find in the Eager Formation are slightly older than those found at the Burgess Shale Lagerstätte. Burgess is Middle Cambrian and the species match the Eager fauna one for one but the Eager fauna are much less varied. The specimens we find are wonderfully preserved and a few have recently been re-named. Learn about new insights into the species we find here and more about the diverse team that has been studying them. Sound the horns, beat the drums and stomp your feet—it's official! The Puntledge Elasmosaur is now British Columbia's Provincial Fossil. Mike Trask found the first elasmosaur in 1988 while exploring the Puntledge River with his daughter. He found the first terrestrial dinosaur remains from Vancouver Island and coined the term "sabre-toothed salmon" of legendary fame. It was Mike's twin brother Pat Trask, who led the excavation of the juvenile elasmosaur from the Trent River back in August 2020. Many talented souls from the Vancouver Island Palaeontological Society and Courtenay Museum joined him.

Victoria is a vertebrate palaeontologist and evolutionary biologist and is the leading expert on the palaeobiology of the armoured dinosaurs known as ankylosaurs. She has named several new species of ankylosaurs, studied how they used and evolved their charismatic armour and weaponry, and investigated how their biogeography was shaped by dispersals between Asia and North America. British Columbia has a rich fossil record spanning over 500 million years of the history of life on Earth. Victoria’s research at the Royal BC Museum will investigate how the ancient plants and animals that lived here responded to changing climates, shifting continents, and mass extinctions. The Carbon Creek Basin site is located just west of Hudson’s Hope in the Peace River area and boasts nearly 1,200 dinosaur tracks from at least 12 different types of dinosaurs—including two dinosaur track types that have not been observed at any other site in the Peace Region…

Vancouver Island Mosasaur 11:53

Vancouver Island holds many wonderful fossils and incredible folk excited to explore them. The Dove Creek Mosasaur, which includes the teeth and lower jawbone of a large marine reptile was discovered by Rick Ross of the Vancouver Island Palaeontological Society, during the construction of the Inland Highway, near the Dove Creek intersection on Vancouver Island, British Columbia. Mosasaurs had a hinged jaw that allowed them to swallow prey larger than themselves. They evolved special pterygoid teeth projecting back into the roof of their mouths that acted as guards against escaping prey. The jawbones Rick found were exposed just up to the hinge. Given the size, this toothy fellow could have been as much as seven (7) metres long and weighed up to a tonne.…

A Taste for Studies: Tortoise Urine, Armadillos, Fried Tarantula & Goat Eyeballs 6:53

A Taste for Studies: Tortoise Urine, Armadillos, Fried Tarantula & Goat Eyeballs While eating study specimens is not in vogue today, it was once common practice for researchers in the 1700-1880s. Charles Darwin belonged to a club dedicated to tasting exotic meats, and in his first book wrote almost three times as much about dishes like armadillo and tortoise urine than he did on the biogeography of his Galapagos finches. One of the most famously strange scientific meals occurred on January 13, 1951, at the 47th Explorers Club Annual Dinner (ECAD) when members purportedly dined on a frozen woolly mammoth. The prehistoric meat was supposedly found on Akutan Island in Alaska, USA, by the eminent polar explorers' Father Bernard Rosecrans Hubbard, “the Glacier Priest,” and Captain George Francis Kosco of the US Navy. This much-publicized meal captured the public’s imagination and became an enduring legend and source of pride for the Club, popularizing an annual menu of “exotics” that continues today, making the Club as well-known for its notorious hors d’oeuvres like fried tarantulas and goat eyeballs as it is for its notable members such as Teddy Roosevelt and Neil Armstrong. The Yale Peabody Museum holds a sample of meat preserved from the 1951 meal, interestingly labeled as a South American Giant Ground Sloth, Megatherium, not Mammoth. The specimen of meat from that famous meal was originally designated BRCM 16925 before a transfer in 2001 from the Bruce Museum to the Yale Peabody Museum of Natural History (New Haven, CT, USA) where it gained the number YPM MAM 14399. The specimen is now permanently deposited in the Yale Peabody Museum with the designation YPM HERR 19475 and is accessible to outside researchers. The meat was never fixed in formalin and was initially stored in isopropyl alcohol before being transferred to ethanol when it arrived at the Peabody Museum. DNA extraction occurred at Yale University in a clean room with equipment reserved exclusively for aDNA analyses. In 2016, Jessica Glass and her colleagues sequenced a fragment of the mitochondrial cytochrome-b gene and studied archival material to verify its identity, which if genuine, would extend the range of Megatherium over 600% and alter views on ground sloth evolution. Their results showed that the meat was not Mammoth or Megatherium, but a bit of Green Sea Turtle, Chelonia mydas. So much for elaborate legends. The prehistoric dinner was likely meant as a publicity stunt. Glass's study emphasizes the value of museums collecting and curating voucher specimens, particularly those used for evidence of extraordinary claims. Not so long before Glass et al. did their experiment, a friend's mother (and my kayaking partners) served up a steak from her freezer to dinner guests in Castlegar that hailed from 1978. Tough? Inedible? I have it on good report that the meat was surprisingly divine. Reference: Glass, J. R., Davis, M., Walsh, T. J., Sargis, E. J., & Caccone, A. (2016).

Oh, Shiny! Pyritized Fossils 3:32

2 yearsที่แล้ว3:32

3:32

We sometimes find fossils preserved by pyrite. They are prized as much for their pleasing gold colouring as for their scientific value as windows into the past. If you have pyrite specimens and want to stop them from decaying, you can give them a 'quick' soak in water (hour max) then wash them off, and dry them thoroughly in a warm oven. Cool, then soak in pure acetone for a couple of days. Then soak in paraloid, a thermoplastic resin surface coating or acetone for a couple of days. Keep them in a sealed container with a desiccant pack afterwards to keep them dry — or leave them out on display to enjoy knowing that the decay will come in time. We do this with cut flowers so why not fossils sometimes? A friend gives her pyrite fossils on display a quick thumb wipe with vaseline or petroleum jelly. I'm not sure if the hydrocarbons there will play nice over time but they will act as a protective barrier.…

Extinct Giants: The Woolly Mammoths. These massive beasts roamed the icy cold tundra of Europe, Asia, and North America from about 300,000 years ago up until about 10,000 years ago making a living by digging through the snow and ice to get to the tough grasses beneath. The last known group of woolly mammoths survived until about 1650 B.C.—over a thousand years after the Pyramids at Giza were built. Will we bring them back? I cannot say for sure but they are a captivating animal in our Earth's history.…

Solving an 85 Million-Year-Old Puzzle — Excavating An Elasmosaur 15:31

3 yearsที่แล้ว15:31

A mighty marine reptile was excavated on the Trent River near Courtenay on the east coast of Vancouver Island, British Columbia, Canada. The excavation is the culmination of a three-year palaeontological puzzle. The fossil remains are those of an elasmosaur — a group of long-necked marine reptiles found in the Late Triassic to the Late Cretaceous some 215 to 80 million years ago. In the case of the Trent River, it is closer to 85 million years old. The marine reptile fossil was excavated 10-meters up high on the cliffs that line the river. It took a month of careful planning, building scaffolding, and amassing climbing gear to aid the team of dedicated souls in unearthing this juvenile elasmosaur. Bits and pieces of him have been eroding out for years — providing clues to the past and a jigsaw puzzle that has finally had the last pieces put together. The first piece of this marine reptile puzzle was found three years ago.…

Love the Wild: Moose / Alces alces 10:47

3 yearsที่แล้ว10:47

10:47

Love the Wild: Moose. One of the most impressive mammals of the Pacific Northwest and the largest living member of the deer family are Moose. They are taller than everyone you know and weighs more than your car. You may encounter them lumbering solo along the edge of rivers and lakes, taking a refreshing swim or happily snacking on short grasses, water plants, woody shrubs and pinecones. You can often see them in Canada and some of the northern regions of the USA going about their business of eating and swimming. The males are called bulls and make quite a racket during mating season, also known as the Rut, using their bugle-like calls to attract a mate. Their impressive headgear can grow up to six feet and are used in displays of posturing, fighting or self-defence with other bulls — generally regarding a lady-moose or cow. Females do not have antlers but certainly, notice them. Once a mate is chosen, the new parents will produce one or two babies or calves. Fully grown, their new young will one day be able to run 55 km per hour and have excellent hearing and sense of smell. Their vision is not that good but their other senses make up for it. The scientific or binomial name for Moose is Alces alces (Linnaeus, 1758). The word moose is borrowed from Algonquian. In Narragansett, moose are called moos and in Eastern Abenaki, this large mammal is called mos . Both are likely derived from moosu , meaning he strips off . The Proto-Algonquian form was mo·swa. In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala , of the Pacific Northwest, moose are known as t̕ła̱wa̱l's — and their large crown of antler are known as wa̱t'łax̱ . I had a close encounter on the Bowron Lake Circuit with a mamma moose, her new calf and a fully grown Grizzly chasing them. I can share that whatever the guidebooks say, a motivated mother and calf can outrun a bear. Maybe not always, but they certainly did that time. Moose are ungulates, mammals with hooves. The first ungulates appear in the fossil record about 50 million years ago. The lineage split, evolving into two groups: those with an even number of toes (Artiodactyls) and those with an uneven number of toes (Perissodactyls). We see the first proto-deer about 35 million years ago. These are the proto-deer like Syndyoceras who shared features with deer, horses, giraffes and antelopes. They had bony skull outgrowths similar to antlers and were found in North America during the Miocene, some 35 million years ago. Ten million years later, we see the first animals you and I would recognize as deer. Moose first appear in the fossil record during the Upper Pleistocene, a time of global glaciation. Moose are gentle creatures if unprovoked. They sometimes ramble into town or buildings if they lose their way. We find them enjoying the water from garden sprinklers, randomly making their way into homes, barns and classrooms in Canada — and likely elsewhere. It is worth doing a Google search of their antics to see all that these massive mammals get up to. They are smart enough to know that living in the woods in hunting season can go poorly, so Moose will gather in downtown Banff and Lake Louise, hiding in plain sight to avoid becoming someone's dinner or trophy. Across Canada today, we live alongside 500,000 to 1,000,000 of their number. Another 200,000 or so live south of us in the northern United States. Across Europe and Asia are another million-plus of their relatives.…

Cretaceous Capilano Fossil Field Trip 8:08

3 yearsที่แล้ว8:08

8:08

Fossil Field Trip to the Cretaceous Capilano Three Brothers Formation — Vancouver has a spectacular mix of mountains, forests, lowlands, inlets and rivers all wrapped lovingly by the deep blue of the Salish Sea. When we look to the North Shore, the backdrop is made more spectacular by the Coast Mountains with a wee bit of the Cascades tucked in behind. 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 bounty of that reservoir flows directly into your cup. If you look down from the reservoir you see the Capilano River as it makes its way to the sea and enters Burrard Inlet. The Capilano River on Vancouver's North Shore flows through the Coast Mountains and our coastal rainforest down to the Capilano watershed en route 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. This area was once the exclusive domain of the Coast Salish First Nations — xʷmə?kʷəyəm (Musqueam), Skwxwú7mesh (Squamish), and səlilwətaɬ (Tsleil-Waututh) Nations until the early 1800s. Many things have changed since then, including the Capilano River's path, water levels and sediment deposition. 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. Both the water and a good deal of sediment from the Capilano would flow into Burrard Inlet if not held back by the 91-metre concrete walls of the Cleveland Dam. While it was not Ernest's intention, his vision and dam had a secondary impact. In moving the mouth of the Capilano River he altered the erosion pattern of the North Shore and unveiled a Cretaceous Plant Fossil outcrop that is part of the Three Brothers Formation. The fossil site is easily accessible from Vancouver and best visited in the summer months when water levels are low. The level of preservation of the fossils is quite good. The state in which they were fossilized, however, was not ideal. They look to have been preserved as debris that gathered in eddies in a stream or delta. There are Cretaceous species found only in the sandstone. You will see exposed shale in the area but it does not contain fossil material. Interesting, but again not fossiliferous, are the many granitic and limestone boulders that look to have been brought down by glaciers from as far away as Texada Island. Cretaceous plant material (and modern material) found here include Poplar (cottonwood) Populus sp. Bigleaf Maple, Acer machphyllum , Alder, Alnus rubra , Buttercup Ranvuculus sp ., Epilobrium , Red cedar, Blackberry and Sword fern. Capilano Fossil Field Trip: From downtown Vancouver, drive north through Stanley Park and over the Lion’s Gate Bridge. Take the North Vancouver exit toward the ferries. Turn right onto Taylor Way and then right again at Clyde Avenue. Look for the Park Royal Hotel. Park anywhere along Clyde Avenue. 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.…

The Fossils and Geology of Haida Gwaii 11:19

3 yearsที่แล้ว11:19

11:19

The islands have gone by many names. To the people who call the islands home, Haida Gwaii means Island of the People , it is a shortened version of an earlier name, Haadala Gwaii-ai, or taken out of concealment. Back at the time of Nangkilslas, it was called Didakwaa Gwaii , or “shoreward country.” By any name, the islands are a place of beauty and spirit and enjoy a special place in both the natural and supernatural world. Haida oral history traces the lineage of their families back to the ocean’s origins. Spear points from Huxley Island confirm a date of between 12,500 - 13,500 years ago. Their stories bear witness to the last ice age, great floods, changes in sea levels and the arrival of the first tree – each binding them closer to the land and sea and enriching our understanding of this special place. The islands form part of Wrangellia, an exotic terrane that includes parts of western British Columbia, Vancouver Island and Alaska. Today, the mist-shrouded archipelago of Haida Gwaii is separated from the British Columbia mainland by Hecate Strait, a 40-mile wide channel of tempestuous water. Haida oral tradition tells of a time when the strait was mostly dry, dotted here and there with lakes. And indeed, during the last ice age, glaciers locked up so much water that the sea level was hundreds of feet lower than it is today. Soil samples from the seafloor of Hecate Strait contain wood, pollen, and other terrestrial plant materials that tell of a tundra-like environment. Whether or not the strait was ever completely dry during these times, it seems that it did at least contain a series of stepping-stone islands and bridges that remained free of ice.…

Fly with me over to Austria in Europe to visit the Hallstatt Limestones. These are the world's richest Triassic ammonite outcrops. Along with diversified cephalopod fauna — orthoceratids, nautiloids, ammonoids — we also see gastropods, bivalves, especially the late Triassic pteriid bivalve Halobia (the halobiids), brachiopods, crinoids and a few corals. We also see a lovely selection of microfauna represented. For microfauna, we see conodonts, foraminifera, sponge spicules, radiolaria, floating crinoids and holothurian sclerites — polyp-like, soft-bodied invertebrate echinozoans often referred to as sea cucumbers because of their similarities in size, elongate shape, and tough skin over a soft interior.…

If you are planning a fossil field trip to Harrison Lake, this is the episode for you! We'll talk about getting there. What to bring and what you'll find. Drive the 30 km up Forestry Road #17, stopping just past Hale Creek at 49.5° N, 121.9° W: paleo-coordinates 42.5° N, 63.4° W, on the west side of Harrison Lake. You'll see Long Island to your right. The first of the yummy fossil exposures are just north of Hale Creek on the west side of the lake on the west side of the road. Drive just past them and park on your right. You are looking for the dark grey rock with the fossils showing up either dark grey, grey-brown or black. You will want to look both in the bedrock, in the loose material that gathers in the ditches and for large dark grey boulders the size of dishwashers packed with Buchia — sometimes made entirely of these densely packed bivalves. Buchia populated our Upper Jurassic and Lower Cretaceous waters like a team sport. When they thrived they really thrived, building up large coquinas of the material that make up much of the rock you will find at Harrison and other sites in the Northern Hemisphere. WHAT TO BRING: As with all trips into British Columbia's wild places, you will want to dress for the weather. This is a good site for hiking boots, raingear, gloves, eye protection and a good geologic hammer and chisel. Fill your gas tank and pack a tasty lunch. You will definitely want to bring your camera for the blocks of Buchia too big to carry. If you take some good photos, I would love to see them. Wear bright clothing and keep your head covered. If it is a larger group, those collecting below may want to consider hardhats in case of small rock falls. These are most often chunks of rock the size of your fist up to the size of a grapefruit — and they pack a punch. Bring a colourful towel or something to lay your keepers on. Once you set down a rock, it is hard to find that keeper pile again as they often blend in with the surroundings. I like to wear one of those lightweight yellow construction vests over whatever I am wearing so my crew and cars can spot me. When you have finished for the day, you can compare your various treasures to see which ones you would like to keep. In British Columbia, you are a steward of the fossil, meaning these all belong to the province but you can keep them safe though cannot sell them or ship them outside British Columbia without a permit. You should be all set to celebrate a glorious day in the beautiful outdoors. I have been asked about collecting four seasons. What do we do about the weather? We live in a rainforest so collecting in sun and rain means your field season is longer. Everyone has a preference. I prefer not to collect in the snow, but I have done. While sunny days are lovely, it can be easier to see the fossil specimens at Harrison when the rock is wet. So, do we do this in the rain? Heck, yeah. Once you get home you can wash and ID your finds. I have put the scientific names here but if they occur as gobblygook, don't worry. Harrison does not have a huge variety of fossil fauna. Essentially, if your find is coiled and round, it is an ammonite. If it is long and straight, it is a belemnite. And if it looks like a wee fat baby oyster, it is Buchia. That is not always true, but it is mostly true. And, you can proudly say that your new fossil babies are between 164.7 - 161.2 million years old. Wow, right? I know. Mindblowing. If you find something you cannot ID, send me a photo on the Fossil Huntress Facebook page and I will help you to identify it. Oh, and do be on the lookout for anything that looks like bone. This site is ripe for finding a marine reptile. Think plesiosaur, mosasaur, elasmosaur, you get the idea. Maybe the next Indiana Jones to get a new species named for them is you!…

British Columbia’s Iconic Spirit Bears 11:08

Visiting the Great Bear Rainforest takes planning and is well worth the trip. You will want to book a guide to lead you through this 6.4 million hectare wilderness on British Columbia's north and central coasts. I recommend searching www.indigenousbc.com for some wonderful knowledgeable First Nation partners on your excursion. This is a journey, an experience you will never forget, so savour every part. As you enter your footfalls are muffled by lush undergrowth, a crush of salal, fallen needles and wood debris that make up this rich, fertile soil. In this temperate rainforest live some of the oldest and largest stands of timber on the planet. This is sacred ground, hallowed ground — though one could say that for every place on Earth — this feels different somehow, older, deeper. This is a forest that whispers secrets for those with ears to hear — in the language of the trees, streams and hidden within every bit of underbrush, every perfectly formed Deer fern ( Struthiopteris spicant ) and Western sword fern, ( Polystichum muntum ) as you gently bushwhack your way through — honouring a leave no trace ethos. As you explore deeper, each breath you take is filled with moist air mingled with the smells of decaying vegetation and fresh growth, new rain and the deep earthy musk of fungi busily at work on the forest floor. The forest itself has a leave no trace mentality in part. Every visible bit of life is a mix of old and new, the fungi breaking down the plant and animal remains, repurposing their life-giving nutrients. It is because of this that we find so few fossils within a rainforest. They are here but not in the way we might think to look for them, at least not with our eyes in the macro-world. Their lineage lives on at the micro-level, bits and pieces embedded within the trees, animals and soil — they form this regions' goût de terroir , the essence of an abiding woodland sphere. The animals that call this forest home live amidst multistoried canopies of Sitka spruce ( Picea stichensis ), western red cedar (Thuja plicata), western hemlock ( Tsuga heterophylla ), amabilis fir ( Abies amabilis ) and Douglas-fir ( Pseudotsuga menziesii ) — each of these pillars of the forest are woven together by salal, lichen and a rich mycorrhizal network beneath the ground. The trees here talk to one another using these fungal networks that connect individual trees and plants together to help transfer water, carbon, nitrogen, nutrients and minerals from the earth to needle and leaf. You are walking through time, literally — each footfall retracing history and those that have come before you, both human and animal. As you explore deeper you come across a vision so remarkable it takes your breath away. Deep in this ancient forest where moss overflows every surface and wilderness abounds, British Columbia's Spirit Bear — Ursus americanus kermodei — reigns supreme.…

Our Palaeontological History: From Fish to Tetrapods 17:44

In the late 1930s, our understanding of the transition of fish to tetrapods — and the eventual jump to modern vertebrates — took an unexpected leap forward. The evolutionary a'ha came from a single partial fossil skull found on the shores of a riverbank in Eastern Canada. Meet the Stegocephalian, Elpistostege watsoni, an extinct genus of finned tetrapodomorphs that lived during the Late Givetian to Early Frasnian of the Late Devonian — 382 million years ago. Elpistostege watsoni — perhaps the sister taxon of all other tetrapods — was first described in 1938 by British palaeontologist and elected Fellow of the Royal Society of London, Thomas Stanley Westoll. Westoll's research interests were wide-ranging. He was a vertebrate palaeontologist and geologist best known for his innovative work on Palaeozoic fishes and their relationships with tetrapods. As a specialist in early fish, Westoll was asked to interpret a single partial skull roof discovered at the Escuminac Formation in Quebec, Canada. His findings gave us the publication that would name Elpistostege watsoni and helped us to better understand the evolution of fishes to tetrapods — four-limbed vertebrates — one of the most important transformations in vertebrate evolution. Hypotheses of tetrapod origins rely heavily on the anatomy of a few tetrapod-like fish fossils from the Middle and Late Devonian, 393–359 million years ago. These taxa — known as elpistostegalians — include Panderichthys, Elpistostege and Tiktaalik — none of which has yet revealed the complete skeletal anatomy of the pectoral fin. None until 2010, that is when a complete 1.57-metre-long articulated specimen was described by Richard Cloutier et al. in 2020. The specimen helped us to understand the origin of the vertebrate hand. It revealed a set of paired fins of Elpistostege containing bones homologous to the phalanges (finger bones) of modern tetrapods and is the most basal tetrapodomorph known to possess them. Once the phalanges were uncovered, prep work began on the fins. The fins were covered in scales and lepidotrichia (fin rays). The work was tiresome, taking more than 2,700 hours of preparation but the results were thrilling. We could now clearly see that the skeleton of the pectoral fin has four proximodistal rows of radials — two of which include branched carpals — as well as two distal rows organized as digits and putative digits. Despite this skeletal pattern — which represents the most tetrapod-like arrangement of bones found in a pectoral fin to date blurring the line between fish and land vertebrates — the fin retains lepidotrichia (those wee fin rays) distal to the radials. This arrangement confirmed an age-old question — showing us for the first time that the origin of phalanges preceded the loss of fin rays, not the other way around. This was evidence for the origins of the vertebrate hand that you and I use today.…
