Palaeontologists would love to know how dinosaurs moved, but it's difficult to predict from fossils. @mesozoicmark.bsky.social & Stephanie Pierce looked at the movement of tegu and opossum hips to understand the restrictions caused by skin and muscles around the joint doi.org/10.1242/jeb....

Perfect descent for Integrity

New paper out on the brain endocast of a distant relative of pangolins: Metacheiromys! We found a possible neurological convergence among myrmecophagous mammals 🧠🐜 Check it out, it's open access! onlinelibrary.wiley.com/doi/10.1111/...

My PhD paper on my beloved cycads and beetles on the cover of Science!!! Check out how we studied thermal infrared as a pollination signal, from molecular mechanisms to the wonders of behavior... science.org/doi/10.1126/...

16 out of 16! First time ever! Doing way better than my March Madness bracket this year...

Osteichthyans--the bony fishes--are by far the most diverse group of living jawed vertebrates. Two papers out today in @nature.com feature remarkable new Chinese fossils that paint a picture of substantial morphological diversity among stem osteichthyans.

I continue to be fascinated by the phenomenon whereby an expert engages with any of the LLMs on their field of expertise and is instantly horrified by the wrong answers, and then goes on to use it for things they are not experts in as though it won’t be just as bad for those.

Thrilled to be featured on the cover of @devdynamics.bsky.social highlighting our 2 anole studies published: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/... & anatomypubs.onlinelibrary.wiley.com/doi/10.1002/... Thanks so much @thomsanger.bsky.social for hosting me when I took this image!

I want every person working for or with ICE, at every level, tried for felony murder. This is now the compromise position.

When @omearabrian.bsky.social saw the manuscript, he described it as: ‘What if this figure could be an entire paper?’ I choose to interpret that as high praise. Now accepted at AmNat: The geometry of macroevolution (with Dan Rabosky). www.journals.uchicago.edu/doi/10.1086/...

I once tried to solve a complex R coding problem with ChatGPT. I lost about an hour to “Sorry, this is the actual name of the function from this package instead” before I gave up, opened the documentation, learned that what I wanted to do didn’t exist, and found a workaround (10 mins).

Mayor Jacob Frey: “To ICE, get the fuck out of Minneapolis.”

I’m excited to be the first ever Artist-in-Residence at #SICB2026! Stop by the @sicbjournals.bsky.social booth during the poster session to chat with me about scientific art and take home some swag with my artwork on it! 🐡

If I saw a "murder hornet," I'd be running in the other direction. But these wee frogs think they're tasty snacks—even though they get stung repeatedly while consuming them. That story and more from @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪

I was collecting #quail #embryos this morning and found an individual with albinism! Look at the lack of pigment in the retinal epithelium! Reminds me of finding a leopard #gecko embryo with the same condition during my PhD.

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.

Yesterday I discovered that ChatGPT's PhD-level expertise didn't extend to bird anatomy. This morning I thought, perhaps I was being too hard on the half-trillion-dollar company. Birds are a little weird, anatomically speaking. Let's try something more familiar. A mammal. Behold.

The team of Ph.D. level experts in ChatGPT apparently doesn't include any anatomists.

The way I convert has always been to start from: 0 C = 32 F Then, every +10 C is +18 F So, 10 C = 50 F 20 C = 68 F 30 C = 86 F (+5 C is +9 F for filling in increments between when needed)

I'm so excited to share my latest paper out now! How did the ancestors of mammals make the switch from sprawling to upright, taking over the world in the process? Spoiler alert; it's complicated! journals.plos.org/plosbiology/...

Today, my successfully defended dissertation was accepted by ProQuest in its final, correctly-formatted version! What a journey it has been to get to this point. #PhDone

Biggest story IMO from the first two meets of Grand Slam Track so far: Jacory Patterson, unsponsored athlete and UPS driver, wins the 400 in Miami this weekend becoming the 26th fastest guy in history (43.98). Finishes 2nd in the Slam, takes home $50k. That's life changing youtu.be/QJ4AhRONMjk?...

🚨 HISTORY LOADING... 🚨 Nike has announced that on June 26th, triple Olympic 1500m champion and mile world record holder Faith Kipyegon will attempt to do what no woman ever has: run a sub-4-minute mile. Kipyegon currently holds the WR at 4:07.64. 💻 Read more: citiusmag.com/articles/fai...

🚨New publication alert!🚨 A big one! It might just be my *biggest* one: doi.org/10.1093/iob/... IMPORTANT THREAD! From the moment Dave Blackburn set me loose at the Florida Museum, I had a marvelous time using diffusible iodine-based contrast-enhanced CT (diceCT) to create anatomical datasets 🧪1/6

Behold the western pygmy possum! This dainty marsupial typically weighs ~0.5 oz (14 g)—that's about as much as a AA battery! It inhabits treetops in forests throughout parts of Australia. As a nectarivore, it mainly feeds on plant nectar. Photo: gilliank, CC BY-NC 4.0, iNaturalist

Absolutely love this illustration!

A multi-tasking #platypus: chewing & scratching at the same time. When #platypuses dive, they cram their cheek pouches full of food, to chew when they surface. Platypuses don't have teeth (they wear down too easily): they've replaced them with ever-growing horny ridges. #Tasmania #fieldwork #WildOz

Don't miss out, we are inviting submissions to our upcoming Special Issue: The Integrative Biology of Exercise. 🧵1/3 journals.biologists.com/jeb/pages/ex...

At this point, the dissertation acknowledgements is definitely giving a shout out to coffee growers, coffee roasters, and the family Rubiaceae for giving rise to such a fine genus. Maybe also Ethiopian farmers for cultivating it and the Ottomans for bringing it to Europe if I feel particularly bold.

Announcing The first found, and most complete, #dinosaur skeleton from the Middle #Jurassic of Scotland! 📢🦖 So delighted to finally be able to share this great new fossil, published today! It was actually the first dinosaur found in #Scotland... thread 🧵 #OpenAccess #fossils doi.org/10.1017/S175...

Cannot give this film enough praise! So excited to see that it won the Oscar for Animated. Absolutely love the detail they put into animal movement and personality.

How do you measure what isn't there? Elska did a fantastic job leading this paper on how we can measure the volume of changing, 3D spaces inside XROMM skeletal animations. And, importantly, how good are those volume measurements? journals.biologists.com/jeb/article/...

Learned today that one of the paleobiologists whose work is strongly influencing my (nearly complete) dissertation, Zofia Kielan-Jaworowska, helped to hide two Jewish women with her family during WWII collections.yadvashem.org/en/righteous...

As somebody who grew up with competitive running just a few miles down the road from Grand Blanc, I can't overstate how exciting it is to watch Fisher's success. Never in my life did I think an American would hold TWO middle distances World Records, let alone somebody from Genesee County, Michigan.

THE DUEL LIVES UP TO THE HYPE 😱 In the Millrose Games 3000m, Grant Fisher and Cole Hocker trade blow after blow, but it’s surprisingly Fisher who kicks last and hardest to blow past the Olympic 1500m champ off the last turn to set a new WORLD RECORD of 7:22.91 to Hocker’s 7:23.14.

GOOSE GETS THE RECORD 🤩 Yared Nuguse gets the Wanamaker Mile threepeat in historic fashion, running an indoor world record of 3:46.63 and holding off Hobbs Kessler (3:46.90) all the way to the line as both Americans finish under Yomif Kejelcha’s 2019 mark of 3:47.01.

2 American under the World Record in the indoor 3000 ...1 hour later... 2 American under the World Record in the indoor Mile 🤯🤯🤯 What a day for US Men's distance running!

We CT scanned thousands of vertebrates from US natural history collections and made them freely available. Countless people have used the data for research (>200 pubs) and to learn anatomy/morphology. www.morphosource.org/projects/000...
