Things happening in the Permian reptile world!

Very excited to share my exploration of the phylogenetics of early ray-finned fishes, out today in the Anatomical Record! Really busy day but I’ll have more info shortly. anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

#2025SVP was a hit for Idaho and the IMNH, with a big showing for Peecook Lab members past and present! @garyonyx-mcgoy.bsky.social @slvrhwk.bsky.social @zhejiang0pterus.bsky.social @paleorob.bsky.social @idahostateucose.bsky.social

People always assume it’s Batesian (you decide), but is Mullerian. #2025SVP

Michigan paleontology family portrait, Birmingham edition #2025SVP

Scenes from the #SVP2025 #2025SVP #paleoart workshop. We had terrific talks from @cpdinosaurs.bsky.social, @tetzoo.bsky.social, @palaeojules.bsky.social and @bobnichollsart.bsky.social, as well as fantastic discussion from attendees. Thanks to everyone who contributed, I hope you all enjoyed it!

Results from tonights Flocking #paleostream! Nanotyrannus, Pteranodon, Phosphorosaurus and Helicoprion!

#2025SVP USA 🇺🇲 🗽 alert: as your travel begins make sure to check your flights proactively! ✈️ One of my legs was cancelled due to the US Govt shutdown, but luckily I caught it. Worse before it'll get better. Stay frosty! See you in Birmingham. 😅🇬🇧🫖

#2025SVP ! If you want to get an idea of the major steps of 🐢turtle🐢 evolution, come to see my talk on Friday, Nov 14, 8:30 AM, Hall 8. My student Guilherme Hermanson talks just before me (8:15). 4 years of macroevolutionary research on turtles went into our talks, covering many unpublished results.

Heads up that the Field Museum is hiring a vertebrate paleontology collections manager: www.fieldmuseum.org/landing/care...

One of the largest temmnospondyls ever to exist: the gigantic Koolasuchus was also the last non-lissamphibian temnospondyl to exist. It survived into the Early Cretaceous of Australia when all other stereospondyls were long gone #temnospondyls #paleoart

Birmingham is best known for South Asian food and claims creation of the ‘balti’ style of curry so that would be the classic thing to eat in the city.

I feel like I say this every year but I really need people to hear it. Halloween is the best American holiday. Just kids outside welcomed into their world, marching around together, showing off their costumes to the elderly, parents meeting parents, neighbors catching up with neighbors.

I made a run to the Field Museum this week and finally saw the Chicago Archaeopteryx. Just wow, it’s a stunner. And the exhibit is a beauty! 🪶 👀🤩 #FossilFriday

Today's bombshell in @nature.com by Lindsay Zanno & James Napoli @jgn-paleo.bsky.social (bit.ly/4qBE6ng) shows that putative juvvy T. rex fossils actually are Nanotyrannus. I reviewed the manuscript, so Nature invited me to write the News & Views commentary. Free link: rdcu.be/eNv94 🦖

Been waiting for the Nanotyrannus news to drop; and checked my phone right when I was in the perfect company 🦖!

Absolutely incredible work here. Just keep clicking back through the quotes.

🚨Call for proposals for Collection Study Grants at the @burkemuseum.bsky.social!! Open to grad students and postdocs for collections-based research, including cross-disciplinary projects. Applications are due December 15, 2025. More information: www.burkemuseum.org/collections-...

True story, folks. Enjoy reading, but please refrain from posting about content until it is presented! #SVP2025 #2025SVP And even then, follow the presenters’ wishes on their slides/posters. @societyofvertpaleo.bsky.social

Super excited to see the #SVP2025 #2025SVP abstract book out! Remember that all abstracts are under embargo ahead of the meeting.

The wife put some work in cutting my remaining hairs before I went to Idaho to tackle the big dead cow. Here's exactly how big (and dead) Junior the Bison latifrons is!

Thanks for the invite to come get plastered on Idaho! Junior's horns put most ceratopsians to shame.

Big week at the @imnh208.bsky.social as one of our *best* Bison latifrons 🤩 🦬 was packed for a long term loan to the Smithsonian in DC! #FossilFriday Named “Junior” btw. 👀 Look for this Idaho treasure next summer. Thanks @mosasaurologist.bsky.social!

Important read by @thomsanger.bsky.social for anyone in science. academic.oup.com/icb/advance-...

Helveticosaurus Lair

I call this piece “Triassic still life” #FossilFriday

Rutgers is looking for a vertebrate paleontologist: www.higheredjobs.com/details.cfm?...

#FossilFriday and the Peecook lab is out in the Pleistocene of Idaho making some new friends! 🦬🐪🦥 @garyonyx-mcgoy.bsky.social @imnh208.bsky.social @idahostateucose.bsky.social

If I squint in yellow and purple I can see a @paleo-hank.bsky.social figure

Happy #Croctober to all who celebrate.

🚨We're hiring! The Sam Noble Oklahoma Museum of Natural History is seeking a tenure-track split position as Assistant Curator of Ichthyology and Assistant Professor of Biological Sciences. Please retweet & share with colleagues! 🐟🐠🧪 Apply here: apply.interfolio.com/174674

We are thrilled to announce that our NEW Large Language Model will be released on 11.18.25.

Please have and encourage patience with US federal offices and our federal colleagues in the coming days. With a US federal government shutdown now in effect, progress on permit requests from federal agencies will very likely be delayed.

(Part 1) This past weekend, Museum of the Rockies staff led the first ever Browning High School Egg Mountain Eggspedition program at the Beatrice R. Taylor Paleontology Research Area near Choteau, Montana. With excitement and curiosity, students began an unforgettable journey.

With a pristine skull, tiny phalanges, gastroliths, & an articulated tail, Zavacephale is the oldest & most complete pachycephalosaur ever found #fossilfriday I had the pleasure of photographing it last week, what a beauty! Congrats to the authors, read about it here: www.nature.com/articles/s41...

Birmingham is built on the Triassic and our main logo for this year's conference features a Triassic reptile, a rhynchosaur, first described by Richard Owen in 1842 from Shropshire, just west of Birmingham. We will be running two Triassic field trips this year, although both are now sold out

Check out the provisional programme for #SVP2025 #2025SVP - the Triassic symposium was so popular they are running it for the entire day! vertpaleo.org/wp-content/u...

Do you like cichlids? Fossils? Fossil cichlids? Would you like to study them as part of a graduate degree at the University of Michigan, joining an NSF-funded project? Get in touch.

What a phone catalog it must be. #FossilFriday

Hearing news that primatologist Prof Jeff Meldrum - probably best known as lone extant academically qualified advocate of the supposed biological reality of #bigfoot - died Tuesday after sudden downturn in health. Thanks Brandon Peecock of Idaho State University for info.

We lost Mark Norell today. Dinosaur hunter extraordinaire. The coolest dude alive. My PhD supervisor. Wherever you are, raise a glass of your favorite lager or single malt, as it is what Mark would want.

Reconstructed skeleton of Spicomellus ('spiky collar'), certainly one of the most unusual dinosaurs known. Found in the mid-Jurassic El Mers Group of Morocco, it is also the oldest definitive ankylosaur.

#FossilFriday: the giant dicynodont Lisowicia from the Upper Triassic of Poland. Lisowicia is the largest known dicynodont (about the size of an elephant.) Lisowicia is also one of the last known dicynodonts. On display at the Museum of Evolution, Warsaw.

It’s finally out! Our work addressing the origins of reptiles is published in PCJ! peercommunityjournal.org/articles/10.... We use novel info gleaned from the scan data of dozens of stem reptiles to substantially revise our understanding of early reptile evolution #paleontology #herpetology

👋 Good-bye "Parareptilia"! Good-bye "Diapsida"! 👋

🚨 REPTILE ALERT 🦎🐍🐢🐊🦉 The backbone of @semifossorial.bsky.social's PhD in my lab is finally out after literally *years* in review, and it's a doozy. Using synchrotron micro-CT scans of MANY amniotes and Paleozoic reptiles we completely restructure the reptile stem lineage across the Permian. 🤩
