I am thrilled to share that I will join the American Museum of Natural History @amnh.org as the Dean of Collections, Curator, and Professor in September!

Happy #FossilFriday!🪨⛏️   🌊This week we have a juvenile colony of the graptolite Hustedograptus found in a Middle Ordovician sandstone olistolith.   📸Thank you to Fernando Lopez for sending us this fossil!   Submit your fossil: tinyurl.com/PSfossilfrid...

So, the grizzly wouldn’t beat the T. rex? (More realistically, the T. rex would never catch a grizzly: a grizzly in full gallop is horrifyingly fast.)

We’re all just trying to exist in a world where colonialism has and continues to exist, but this situation calls for some very pointed eyebrow raising given the UK’s particular collecting legacy.

1) besser in Abu Dhabi öffentlich zugänglich, als vergessen in irgend einem privaten Keller 2) besser in Abu Dhabi öffentlich ausgestellt als verrottend in einem Keller des NHMUK o.ä 3) UK sollte NHMUK endlich ordentlich finanziert werden. 4) auch in D sind öff. Museen massiv unterfinanziert

Constantly amazed at the power of trace fossils. “As we examined fossilized footprints in a traditional waltz pattern at dig sites across multiple continents, it became clear that dinosaurs did in fact throw lavish 15th birthday parties for their female offspring…”

Seahorsification. I skimmed the paper, this is the real deal, the species most closely related to Australyichthys are indeed elongate ropelike pipefishes! 🧪🦑

Looks like a seahorse, but it’s not. It evolved the same body plan independently! journaloflostspecies.org/index.php/jl...

Amazing day for carnivorous mammal enthusiasts out there 🐺🦁🐻🦝🦦two new papers out in @royalsociety.org 🥳: Vankelst et al 2026 in Proceedings B doi.org/10.1098/rspb... and @val-fisch.bsky.social & Solé et al. 2026 in Biology Letters doi.org/10.1098/rsbl... More details below👇🧵1/9

This persecution of Fauci is unacceptable. 7.1 million people died of Covid-19 since it jumped to humans. Dozens of viruses out there also have potential to jump anytime and cause similar deaths. Nobody will be willing or able to fight them. Thanks Rand Paul and RFK jr. wapo.st/3TAPlAj

The 85-year-old doctor, once the head of the government’s covid response, now faces mounting congressional threats and legal risks.

Welcome to the CAMBRIAN FECAL REVOLUTION. We didn't name it the Cambrian fecal explosion for obvious reasons. I'm happy to share this paper on fecal matter and its role in Cambrian ecosystems. So if you want to read a really shitty paper (50 days free access): authors.elsevier.com/a/1nYg8cZ3X7...

I love how new audiences continue to discover & appreciate this diagram from my 2014 book 'Dinosaurs Without Bones' (@pegasus-books.bsky.social). Before including it in the book, I imagined, calculated, & drew it, then asked a physicist to peer-review it. Physics, math, & paleontology made fun! 🧪🦕🤮

Look, a lot of people are clowning on Adam O'Neal for taking a job for which he wasn't qualified in service of helping a billionaire curry favor with an autocrat, using his position to build an unpopular and facile video series and then bailing on the role in barely over a year.

also i think it is quite neat that we still have snails that look similar-ish to Dendropupa (photo by @tohru_menghuali) link: www.instagram.com/p/DJ3kNzDRpJ_/

Cameo: this wasn't part of the script but I had the power to #InsertAnInvert, so I specifically asked @kiabugboy.bsky.social to model us Dendropupa vetusta, the oldest land snail, which was also found in Joggins Formation. Please admire the snails. This is important.

I have to say it: technically with our 🦷 paper (www.science.org/doi/10.1126/...) and Jack's Gabi paper (www.science.org/doi/10.1126/...) 50% of the Science covers from July are from our lab 😎🔥

#FossilFriday flashback: My lab published two major papers this month on 1) dental functional morphology and 2) vertebrate paleontology & paleobiogeography. It made me so proud of the research teams I've been a part of over the past decade, but it also prompted reflection on my academic path (🧵1/5)

omg just saw the odyssey and I will say worth price of admission to hear Odysseus stare into camera and say “we are entering the bronze age collapse”

how in the space of a week do both frontier labs go 'oops we forgot to unplug it from internet first' -- in violation of basic security practices, and yet this story will somehow be remembered forever history as a landmark 'advance in AI' that rendered human security experts irrelevant...
