My student, Evan Cerna presenting at #2025SVP on a new Cretaceous dinosaur trackway in the Glen Rose Formation in central Texas!

I am on my way home to Toronto and the aurorae are absolutely phenomenal. If you are anywhere in the northern half of the continent, get outside and look up! Or better still, put your camera on a 10 second exposure and point it up.

I wanted to offer some thoughts on the Gates climate memo that has been circulating this week. While I can't directly speak for others, I can say that my own response is one of dismay & deep frustration (and that this view is shared by many climate/Earth scientists). [1/n]

In Ithaca, there's a museum that has the largest collections of fossils from New York AND Antarctica AND Venezuela. It's grown from a small collection purchased by Ezra Cornell himself nearly two centuries ago. It will now close in January without help: www.timesunion.com/state/articl...

My latest for @nytimes.com! For 40 years, paleontologists have grappled over whether a small tyrannosaur — named Nanotyrannus — was its own animal, or simply a teenage T.rex. The debate has been ... contentious. Which is why it's so fun to finally be able to say this: Folks? Nanotyrannus is real.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

Biggest takeaway from this study: Dinosaurs were doing fine right up until the impact! #FossilFriday

Combining the new dates for the San Juan Basin dinosaurs with ecological modeling of dinosaur occurrences across North America, we show that dinosaurs were not declining leading up to the end-Cretaceous extinctions. Instead, the were diverse and living in provincial northern and southern communities

New dates for the Naashobito faunas from New Mexico help show that dinosaur diversity was declining making them weren’t extinction. Instead dinosaurs were diverse and thriving right up until the end-Cretaceous asteroid impact 🧪🪨🦕🦖☄️☠️

These were the dinosaurs that faced the asteroid. Some of the last survivors. They lived in New Mexico, 66 million years ago. Among them was Alamosaurus, the size of a jetplane. We unveiled them, and their true age, today in a new paper in @science.org !

New dates on fossils from New Mexico reveal a community of dinosaurs that were thriving right before the asteroid strike, including 80-foot-long, 30-ton giants like Alamosaurus. I’ll tell you more in my latest for NatGeo. 🧪

New evidence reveals dinosaurs were thriving right up to the moment the asteroid hit

Newly dated fossils from New Mexico challenge the idea that dinosaurs were in decline—and suggest instead they had formed flourishing communities.

nationalgeographic.com

Paleontologists still debate whether dinosaurs were in decline even before the asteroid wiped them out. New precise dating techniques of a century-old fossil site in New Mexico are giving scientists a better idea.

What really killed the dinosaurs? These rocks may unlock the answer.

New dating techniques at a fossil site in New Mexico attempt to dispel the theory that dinosaurs were already in decline before the fateful asteroid hit.

Lastly, this N-S bioprovincialism persists after the mass extinction and is seen in early Paleocene mammalian communities suggesting that the biogeographic structure was not destroyed by the mass extinction event.

We then used ecological modeling to show dinosaur communities were partitioned into two different bioprovinces during the terminal Cretaceous across western North America, driven by differences in climate. This suggests dinosaurs in North America diverse & thriving leading up to the K/Pg boundary.

This Naashoibito dinosaur community was dominated by the giant sauropod Alamosaurus and crested Lambeosaurine hadrosaurs, which is a marked difference than the coeval Hell Creek Formation.

Using magnetostratigraphy and Ar/Ar geochronology, we were able to constrain the age of Naashoibito Member deposition, and the major vertebrate fossil localities, to no older than 66.38 Mya.

We provide new age constraints on the Naashoibito Member in the San Juan Basin of NW New Mexico showing these rocks, and their unique dinosaurs, are among the last non-avian dinosaurs from the last 340 Kyr of the Cretaceous, contemporaneous with the famous Hell Creek fauna. doi.org/10.1126/scie...

Our new paper is out in @science.org #ScienceResearch Our understanding of the dinosaurs at the very end of the Cretaceous is limited by few localities. What dinosaur biogeographic patterns were present leading up the K/Pg boundary? What can these tell us about end Cretaceous dinosaur communities

New paper today in @science.org: we date the Naashoibito Member (New Mexico) to 66.4–66.0 Ma, coeval with the Hell Creek, with important remarks on pre-extinction dinosaur diversity & regionalisation in North America 🦖🦕☄1/ Art: @nataliajagielska.bsky.social 🔗 www.science.org/doi/10.1126/...
