Recently our palaeontology team took a collecting trip to the Cat Head site, in collaboration with Kinonjeoshtegon First Nation. This site is known globally for its preservation of Ordovician Period fossils, and new samples will support research on the conditions under which it formed. #FossilFriday

I'm happy to introduce the newest Cambrian critter 'Tentalus spencensis' from the Spence Shale of Utah. Publications out today in Geological Magazine (Open Access). Thanks to Karma Nanglu and Paul Jamison for their help with the paper. Link: www.cambridge.org/core/journal...

Glad to share our latest article on the "co-coordinated stasis of large mammal diversity with the environments". Long in reviews it is finally out--a work done during the post-doc of Simona Bekeraitė app.pan.pl/article/item... 1/4 🧪 ⚒️ #Paleobio #EvoBio #Geology #Macroecology

Creative use of autocorrelation in analyzing trace fossils in the Ediacaran-Cambrian explosion: "..lack of temporal correlation in the studied Ediacaran trajectories and its presence in...Cambrian trajectories, indicating time-tuned behaviours.." arxiv.org/pdf/2509.02940 🧪 ⚒️ #Paleobio #EvoBio

For anyone in Toronto in Oct. - 50 years of discovery: #BurgessShale research @romtoronto.bsky.social www.rom.on.ca/whats-on/eve... #FossilFriday

Last #FossilFriday I had the pleasure of visiting the @romtoronto.bsky.social and checking out the Dawn of Life gallery! I’ll dig into my favorite individual fossils soon, but the exhibit was a gorgeous mix of science, art and specimens and I loved that it featured specimens from across Canada! 🇨🇦

This week's #FossilFriday example is small... but luckily, there's a big model showing what it might have looked like alive! Habelia optata was an arthropod that lived in the waters 506 million years ago during the Cambrian. This fossil was found in British Columbia, Canada! 🇨🇦

Job Alert‼️ Postdoctoral Fellow opportunity in paleontology/biology at the University of Alabama Museums: careers.ua.edu/jobs/688232b... Aim: assess biotic interactions using mollusks from both sides of the Isthmus of Panama. Please share widely! @paleosoc.bsky.social @almnh.bsky.social

Welcome back to #fossilfriday Here are the boney plates from a Placoderm fish. These come from the Middle Devonian (Givetian) Silica Shale Formation in Sylvania, Ohio. I am unsure as to what genus and species of the fish plates belong to. -Image is from Wikipedia Commons

I missed #FossilFriday so here are some cool #Eocene flower #fossils from British Columbia’s Allenby Formation. Collected near Princeton, BC. #PaleoSky #Palaeontology #Paleontology #Palaeobotany #Paleobotany

How do scientists name a newly described species? Museum Postdoctoral Researcher Russell Bicknell, who recently had a trilobite named after himself, explains!

Eophrynus prestvicii, the Coseley Spider, is an extremely well-preserved, 300-million-year-old #arachnid discovered near Dudley. Though it looks like modern #spiders, it was unable to spin a web, instead catching prey using powerful jaws! #FossilFriday #LapworthRocks #geology #palaeontology

Fun day trip this week! On a warm, sunny July day, paleontologist Melina Jobbins and her team search an old rock quarry near Lundar, Man., for 390-million-year-old fossils of an extinct fish that swam in what was once a vast inland sea. www.cbc.ca/news/canada/... @umanitoba.bsky.social

Just returned from a fantastic week of field work along the coasts of Lake Winnipeg. Many amazing #Ordovician #fossils now safely back at the museum and lots of new ideas for advancing research in the area. Couldn't have asked for a better team! #FossilFriday #ManitobaFossils

The Manitoba Museum is seeking a new Director of Research, Collections, and Exhibitions and Chief Curator: manitobamuseum.ca/director-of-...

Meet Mirasaura, a newly described Triassic reptile that sported a sail of feather-like structures that resembled a well-coiffed pompadour. Congrats to @stephanspiekman.bsky.social, @hanssues.bsky.social and the rest of their team on a fascinating discovery! www.smithsonianmag.com/blogs/nation...

Meet Palaeocampa anthrax, a newly discovered Carboniferous lobopodian, and 150 year old mystery fossil! Palaeocampa is an exceptional lobopodian - it lived in rivers and lakes, bristled with thousands of poisonous spines, and more. 🧵 Open access: nature.com/articles/s42...

Once again, the @oupaleobiology.bsky.social's upcoming field season to the early Paleozoic of Anticosti Island is starting to feel real ⛏️

Fieldtrip day 1: today we visited not 1 but 2 sites with fossil plants 🌿⛏️🤩 Here's a nice Stigmaria, the rooting structure of a lycopsid tree from the latest Carboniferous, a little over 300 million year ago. (and yes it is extremely warm 🌡️)

A photo I took of an enigmatic looking #fossil (Aysheaia pedunculata) 32 years ago at the Burgess Shale (Middle #Cambrian) and the same specimen after being prepped, as it appears on the Royal Ontario Museum’s Burgess Shale website. #PaleoSky #FossilFriday #Palaeontology #Paleontology #Lobopodia

Having a great time visiting the Musée de paléontologie et de l'évolution. The Neuville Formation (Ordovician) contains one the most spectacularly preserved echinoderm Lagerstätte I've ever seen. Very excited to be working on this! Here's a beautiful Ectenocrinus w/ rhombiferan blastozoans attached

Another new horseshoe crab, this time the first known Silurian species, filling a 63 million year gap in the horseshoe crab fossil record. This specimen was actually found by Sam Ciurca 50 years ago - another example of the importance of museum collections! ⚒️🧪 doi.org/10.1098/rspb...

Coral montage for #FossilFriday, because who doesn't love coral? I love Paleozoic tetra corals and also what silica replacement does to them, especially. Check out that Beekite on the two middle right! Swoon.

So, Tom, how have you been procrastinating the arthropod cuticle preservation paper? Oh, you know . . . #Devonian #dunkleosteus #3dprinting
