Dinosaur of the day Dracovenator, a close relative of Dilophosaurus from the Jurassic of South Africa.

In dinosaur news this week:

  • Brain size varied in dinosaurs
  • Turns out, the dinosaur Thescelosaurus had a powerful sense of smell, a sensitive vestibular system, but terrible hearing—all which may mean it was a burrower
  • A new hiking trail with 134 sauropod dinosaur footprints is now open to the public in Colorado, according to The Denver Gazette
  • The Jean & Ric Edelman Fossil Park is opening in June in New Jersey


Listener Questions:

  • What would a real "modern tyrannosaur" look like?
  • Update on the Ornithoscelida debate (where theropods and ornithischians are grouped together). We also explain Saurischia (sauropods + theropods) and Phytodinosauria/Ornithischiformes (sauropods + ornithischians).


Fun Fact: According to the Dinosaur Heresies, pterosaurs are dinosaurs.
