We'll close out this #FossilFriday with the obvious choice of Nanotyrannus. I couldn't share this CT scanning session at the time (June 2023) but can now. @JGN_Paleo brought the holotype Cleveland skull he had on loan & @goCMNH VP curator Caitlin Colleary & I joined in the fun!

.@SBundell at @Nature, knowing that I had written the News & Views commentary on the Zanno & Napoli article on Nanotyrannus, contacted me earlier this week to film a quick video that provides background. Shamini did a great job with it. I need a haircut. https://t.co/XeY874Jfle

Today's bombshell in @Nature by Lindsay Zanno & James Napoli ( https://t.co/D4kdZN69dC) 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: https://t.co/cRDXEpOn3u 🦖

Federal investigators are taking a closer look at the Black Lives Matter Global Network Foundation’s finances. What could this probe mean for transparency, accountability, and the broader nonprofit sector?

An excellent commentary on the article by @WitmerLab. Strongly recommend folks give it a read, especially those taking their first steps in the field.

It's #NationalFossilDay here in the USA, so here's a photo of our T. rex brain endocast based on a US national fossil—AMNH 5117. The surprise was to see it on exhibit in Japan at the Fukui Prefectural Dinosaur Museum @FukuiDinosaurs. Print one of your own! https://t.co/lbuBVoPJxH

If you haven't read—or re-read in a while—Bakker's 1986 classic The Dinosaur Heresies, it's well worth doing. I read it in '86 & again on my recent trip to Japan. Got a pb copy for $10 for the long trip (1st photo) rather than take my signed 1st ed (with Gurche-signed cover)! 🦖

Excited to see this new #OA article out on turtle head vasculature, led by @SeishiroTada (part of his PhD diss)! So much fun injection, dissection, sawing, & µCT of turtles & lizards in the lab with Sei and DJ Morgan—leading to this really nice article! https://t.co/sDEg26CbwF 🐢

We have a new paper out! Turtle ancestors evolved a shell—but what else? We found that an unique rostral vasculature was also obtained gradually along the lineage, and that an earliest turtle Proganochelys likely retained a mostly ancestral state!🐢 https://t.co/aTZWkAzrMi

Happy Birthday, T. rex! 🎉🎂 120 years ago today (1905), fossils collected in Montana were given the name Tyrannosaurus rex. Here’s the "sitting" mount of the T. rex known as Bucky (TCM 2001.90.1) at the National Museum of Nature & Science which I visited last week in Tokyo. 🦖

After spending so much time with smallest/youngest specimen of Tarbosaurus, I'm thrilled finally to be face to face with among the largest known Tarbosaurus specimens (MPC-D 107/2) at the stunning Fukui Prefecture Dinosaur Museum @FukuiDinosaurs.

Having a great time in the dinosaur collections of the National Museum of Nature & Science in Tsukuba, Japan, just outside Tokyo. Many wonderful fossils like this beautiful skull of Thescelosaurus NSM PV 24661.

Shaken to hear Mark Norell passed—good friend, trusted colleague, giant in our field. Coincidentally I got the news as I was working on my talk for the Intl. Symp. on Asian Dinosaurs in Fukui. Here's my slide on Mark’s impact on Asian dinosaur science. It hurt to add 1957–2025.😢

Feeling the incalculable loss of Mark Norell (1957-2025): wonderful scientist and cherished friend. His influence will continue through his many mentees and the science he did and inspired.

Here's the shot from that 1995 photoshoot they used in the article. My research lab wasn't ready yet, so the photog came to my house & I pulled my T. rex skull out of the garage & set it up on the lawn! 30 years later, I'm still teaching anatomy & doing paleo research! 💀🦖 2/2

30 years ago today (Sept 1, 1995) I started my job at @OhioU & @OUHCOM! I'm not done yet, but it's been a pretty fulfilling run, watching students succeed, the lab grow, & science happening! Minimally we moved from that cheesy clipart pick-&-scalpel logo to a snazzier logo! 1/1

A sad #FossilFriday with the news that legendary Mongolian dinosaur paleontologist Rinchen Barsbold passed away yesterday at the age of 90. I'm honored to have shaken his hand and more so to have coauthored with him twice, on Tarbosaurus and on Avimimus. R.I.P. Dr. Barsbold. 🦖

Excited to have this new #OA article out in @FossilsMDPI ( https://t.co/QUIeUbIINZ), documenting the loss of cranial kinesis in phorusrhacid terror birds in connection with their remarkable hatchet-like feeding style. Dino Degrange ably led the project & we've got more on the way!
