Dinosaur of the day Tatankacephalus, the "bison-headed" armored dinosaur.

In dinosaur news this week:

  • A skull, including a braincase, is enough to tell us there’s a new Psittacosaurus species, Psittacosaurus houi
  • Studying dinosaur brains is an evolving field
  • Brain size varied in dinosaurs
  • Ceratopsians became less intelligent and had worse hearing and a worse sense of smell as they evolved to larger sizes
  • Ornithopods, and especially hadrosaurs, had bigger brains than we thought
  • Thescelosaurus had a powerful sense of smell, a sensitive vestibular system, but terrible hearing—all which may mean it was a burrower
  • A study of spinosaur brains and skulls helps show how they adapted to eat fish
  • Living birds have high EQs which they evolved from non-avian dinosaurs (although we don't really use EQs much anymore)
  • Shuvuuia may not have had specialized hearing
  • The enantiornithe Navaornis hestiae tells us a lot about bird brains
  • Unique brain shape in birds may be why birds survived non-avian dinosaurs after the mass extinction event
  • Parrots and humans may use similar brain mechanisms to produce complex sounds
  • Bird brains (and our brains) are wired for taking turns when communicating
  • T. rex had the intelligence of a baboon paper
  • Rebuttal to T. rex baboon intelligence paper
