  • 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
