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
