First paper of 2026 is out for #FossilFriday, and the first of probably several ornithischian papers over the next interval. Here my coauthors and I describe some tantalizing bits that suggest that ornithischian diversity in the Morrison Formation is higher than previously recognized.

For #FossilFriday the first 7 caudal (tail) vertebrae from the #IsleofWight iguanodontian dinosaur Comptonatus chasei. A hefty tail providing lots of muscle attachments including powerful muscles from the back of the thigh. So different from large mammals, think of the elephant’s flimsy tail.

I'm intrigued about how this is next week's episode, @fossilrob.bsky.social, because unless I've had some sort of episode, I don't think we have actually recorded this one yet... this was just you telling me about what you were going to tell me about. Wasn't it?

In the forthcoming Morrison Formation special issue of the NMMNS Bulletin, Steve Holland and I examined whether we could identify ecological gradients in the Morrison Fm. We can't, and we think this is due to sampling. Download a copy here: naturalhistorymuseum-my.sharepoint.com/:b:/g/person...

Trump on NATO: "I've always said, will they be there if we ever needed them? That's really the ultimate test. I'm not sure of that. We've never needed them. They'll say they sent some troops to Afghanistan and this or that. And they did. They stayed a little back, off the front lines."

Great beer, great people, great audience for my talk. GREAT new fossil Felix Augustin and I were studying, the latest in the rhabdodontids-are-ceratopsians saga. Stay tuned!

Good lord @stevebrusatte.bsky.social I fear you may have jumped the shark with that quote 😁😁😁
Previous estimates put T. rex’s lifespan at about 30 years, and the dinosaurs were thought to have reached their full size around age 20 to 25. New research rewrites that story. “It took the prince a lot longer to grow into the king,” says a paleontologist not involved in the work.
