Dinosaur of the day Kayentavenator, an Early Jurassic dinosaur that lived alongside Dilophosaurus, Scutellosaurus, and Megapnosaurus/Coelophysis.

In dinosaur news this week:

• There’s a new tyrannosaur, Asiatyrannus xui, with a surprisingly deep skull for a tyrannosaur of its size
• There’s evidence of a new tyrannosauroid in northeastern Thailand
• A new study shows how biting stress and strain vary in different sized tyrannosaurs
• Dinosaurs, like Tyrannosaurus rex, probably got a lot bigger than we’ve seen in the fossil record
• A new device makes it easier for museums to digitize their fossils and share with people around the world

This episode is brought to you by Brilliant, the app with thousands of bite-sized, interactive lessons on cutting-edge topics. Anyone interested in paleontology will particularly like their courses in chemistry, which underlie the fossilization process, as well as data analysis, used to model dinosaur populations.
