Join us July 25th as we stream for a NEW COLLABORATIVE EXPEDITION to the Cretaceous of Kazakhstan, co-lead by Jared Shiffert, our own Dr. Napoli, & the Kyzylorda Regional Museum. Your support will ensure that the 2026 joint expedition will be the first of many!

Resolving the “ontogeny problem” in vertebrate paleontology, recently published in Paleobiology, by @jgn-paleo.bsky.social - this is a *must read*, esp. for those in the archosaur realm www.cambridge.org/core/journal...

It's been far too long since Tylosaurus news...so here's another NEW TYLOSAURUS PAPER! 🦎 From me & Mike² (Everhart & Polcyn) For the first time in over 150 years, the holotype of Tylosaurus proriger is fully described & figured in detail. Incredible artwork by Andrey Atuchin

MARK YOUR CALENDARS: LIVESTREAM. JULY 25. Something very different this time.... stay tuned!! ✈️⛏️🦴

King in Black A few weeks late but here’s a Tylosaurus rex life reconstruction . Huge congrats to @tyrantlzrdqueen.bsky.social and her team on publishing the work on the king of the seaway. #TylosaurusTuesday #paleoart #sciart #art

T. rex vs. T. rex.

There's a new T. rex in town. Not a dinosaur, but a mosasaur. Tylosaurus rex. About the same size as Tyrannosaurus rex. Top predator, but in the sea. Nasty bite. The terror of ancient Texas! Described by pal @tyrantlzrdqueen.bsky.social My thoughts @cnn.com edition.cnn.com/2026/05/28/s...

There’s a newly crowned T. rex. This one, called Tylosaurus rex, was a tyrant of the sea and mosasaur spanning up to 43 feet in length.

Meet 'the ocean version of T. rex'—apex predator Tylosaurus rex, ruler of Cretaceous seas. I spoke to paleontologist @tyrantlzrdqueen.bsky.social for @cnn.com about how she noticed something unusual about Texas fossils assigned to a known mosasaur & ended up describing a new species 🧪 #FossilFriday

#FossilFriday I mostly draw mammals, but I've always been fascinated by marine reptiles. So after the new paper by @tyrantlzrdqueen.bsky.social et al announced a new species of #Tylosaurus, T. rex, I had to take a crack at a reconstruction! Fun to try something different..

This is why one should avoid using the abbreviation "T. rex" from here on out - 'cause now there are *two* of them. Welcome to science, Tylosaurus rex! (Take a back seat for once, tyrannosaurs.) #FossilFriday 🧪

Everything IS bigger in Texas... Introducing TYLOSAURUS REX–“TEX”. A monster animal, a monster paper, & a monster project that I am *so* excited to finally share with everyone after ~5 yrs. Huge thanks to my coauthors, Mike & Ron, & to Alderon Games for bringing our lad to life!! #FossilFriday

Fun fact: the length of the Tylosaurus from #TheDinosaurs is 12.4m/40.7ft. This meakes it larger than the biggest Tylosaurus proriger and puts it in the size range of Tylosaurus rex.

This week's free newsletter is out! Come learn about the new T. rex in town - Tylosaurus rex. And if you haven't yet, sign up for The Boneyard on Buttondown

Friday Fragments #14

We've got a new mosasaur, and it's a *big one.*

This research was led by Museum Research Associate Amelia Zietlow, who began this work as a comparative biology Ph.D. student in the Museum’s Richard Gilder Graduate School. The study updates a dataset crucial for studying mosasaur evolution! Image courtesy of Alderon Games - Path of Titans

🚨 There’s a new T. rex in town! A newly described species of giant mosasaur—growing up to 43 ft long—has been named Tylosaurus rex, or “king of the tylosaurs.” One of the largest mosasaurs known to date, this T. rex might be every bit as fearsome as the original “tyrant king.” Read more.👇

New research describes Tylosaurus rex from more than a dozen previously known fossils.

We are excited to announce a fourth new subspecies of Tylosaurus in Path of Titans, Tylosaurus Rex! Check out the interview with Amelia Zietlow, one of the amazing paleontologists who have described this new species of Tylosaurus! #pathoftitans #dinosaurs #game #interview #paleontology #Tylosaurus

But the new T.rex is actually just the appetizer: @tyrantlzrdqueen.bsky.social also went and re-measured every mosasaur specimen (as well as a bunch of living lizards) she could, in order to create a good dataset for the family, which has been released as part of the paper's supplemental data.

For decades, people have pulled massive remains of Tylosaurus -- an enormous sea-going lizard -- out of North Texas creeks. Really massive remains. So massive that researchers like Mike Polcyn and @tyrantlzrdqueen.bsky.social increasingly wondered if they were a new species. Turns out they are!

Equipped with powerful jaws and finely serrated teeth, paleontologists say the 43-foot-long prehistoric marine reptile deserves the name Tylosaurus rex.

🚨NEW STUDY DROP🚨 New species of giant mosasaur, Tylosaurus rex, based on over 12 specimens previously referred to other species of Tylosaurus. Culmination of the PhD research of lead author @tyrantlzrdqueen.bsky.social the paper is extremely thorough! 🎨: AlderonGames + @formorphology.bsky.social

@tyrantlzrdqueen.bsky.social will do a live stream today discussing the work. bsky.app/profile/skel...

Howdy everyone! Join us this THURSDAY, MAY 21 at 830 PM EST as we stream Path of Titans to take their newest Tylosaurus model out for a spin! Be there or be square...!

🚨SCOOP, EXTRY, READ ALL ABOUT IT🚨 Friendship ended with T.rex! T.rex is my new best friend! I'll tell you all about it over at National Geographic.

We get a new mosasaur today! T. rex! As in, Tylosaurus rex. Congrats to @tyrantlzrdqueen.bsky.social and colleagues on the publication. digitallibrary.amnh.org/items/dbbf9d...

It's been much too long since my last #MosasaurMonday, so enjoy some southwestern seaway vibes from my trip to Dallas in 2023! 🌊🦎 Fossils are bits & bobs of Tylosaurus, [Lizard] King of the once-flooded Lone Star State. RIP Tylosaurus, you would have loved brisket sandwich 🤘😞

On NSF’s postdoc page, the biology and earth science fields have been completely eliminated; the only remaining fellowships are in math, astronomy, engineering, and “entrepreneurship.” Weird choice not to support research on the life support system for 8 billion people. www.nsf.gov/funding/post...

Presenting on new mosasaur heads for this #FossilFriday at NDGS, including the debut to an audience of this huge mosasaur noggin that we built last year.

Happy #FossilFriday! Our new exhibit at the Castle, PREHISTORIC WISCONSIN, opens NEXT WEEK on 3/26! If you're in the area, be sure to swing by - Chase & I will be hanging out in the exhibit from 1-3pm on April 1, 3, & 6 with answers to questions & bonus specimens from collections.

🚨Science news! Recent research led by Meghan Forcellati, a comparative biology Ph.D. student in the Museum’s Richard Gilder Graduate School, has uncovered new clues about reptile evolution by studying the bony encasements of the inner ears of living lizards and snakes.

Bony Inner Ears Offer Clues to Lizard Evolution | AMNH

Scientists hoping to reconstruct how extinct lizards and snakes lived have turned their attention to the inner ear.
