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
