Nanotyrannus is real. For years I’ve considered many mid-sized gracile tyrannosaurs to be juvenile T. rex. But I was wrong. This stunning new skeleton of a mature long-armed small tyrannosaur is clearly a different species. Isn’t science fun?! https://t.co/EUWFzZyos6

As a scientist in the dinosaur ontogeny game for over 20yrs, I can say that most of my colleagues were skeptical of Nanotyrannus. Now the most outspoken critics buy it. Thrilled to see this incredible work out. Huge congrats to @ExpeditionLive & @JGN_Paleo https://t.co/czR1zOtZNk

The @ATGUSAMade Buddy Sled is a specific solution I kneeded for a school I’ve been helping. For my own workouts, I use the resisted treadmill - and all my shoes and equipment are on sale for the holidays! This video also covers the history of sled dragging:

If it weren't for Lindsay's hard work, grit, and determination, the Dueling Dinosaurs may never have made it to a museum collection. Our field owes her, and everyone who worked with her to bring these specimens into the public trust, a debt of gratitude.

It's real. And it's spectacular. Sometimes, one fossil really can change everything you think you know. NEW PAPER (see bottom of thread) AND 🧵

Whew. A little thing happened today. Honored to have done this work with the outstanding @JGN_Paleo. I was a skeptic when I stepped into this, but no denying it #Nanotyrannus is valid. @JGN_Paleo and I left no stone unturned. And by the way, there are juvi T. rex, stay tuned...

Fun day out with Phil Currie— he took me out to see the Danek Edmontosaurus Bonebed. This highly productive site is within the city of Edmonton & is the location of the University of Alberta’s undergrad palaeo field school.

New dates for a long-debated New Mexico fossil site reveal that dinosaurs were thriving and regionally diverse until the end-Cretaceous asteroid strike 66 million years ago, according to a new study in Science. https://t.co/XMl7UqpXHa

"Perhaps the most accomplished vertebrate paleontologist of his generation." This one by Jim Clark, who knew Mark from childhood. It's lovely.

Happy #FossilFriday! The horned #dinosaurs #Stellasaurus (#MOR492), #Einiosaurus (#MOR456_8-9-6-1), & #Achelousaurus (#MOR485) are closely related but found in different layers of the #Cretaceous Two Medicine Formation in #Montana. They may be members of an evolutionary lineage.

Which bulb produces more near-infrared (NIR) light? Here we have an IR-SENSE photo comparing different light bulbs being operated at the same power. All appear as "warm white" color to the eye but the difference in the amount of invisible NIR light present is

New findings offer insights into Wyoming’s “dinosaur mummies,” revealing that the stunningly preserved skin, spikes, and hooves of duck-billed dinosaurs are not fossilized flesh at all, but delicate clay molds formed by microbes as the creatures decayed, researchers report in

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 @ScienceMagazine!
