Definition
Terrestrial, moved in herds, erect limb posture, moved one limb at a time, protective of young (once hatched), herd constantly moved to find new food
Term

Only present in front of nasals in ceratopsians. First appears in Psittacosaurus
Term
Henry Fairfield Osborn
Definition
Decided to search for human missing link fossils in Mongolia. Instead found dinosaurs
Term
Roy Chapman Andrews

Term
"Cold Blooded" animals aka:
Definition
Ectothermic, Brady Metabolic, Poikilotherms
Term
Robert Bakker
Definition
Douchebag (according to Busbey) Tried to reconstruct dinosaur predator/prey ratios. Simply fabricated a lot of his info to make it fit. Plus, predator prey ratios simply dont always work to determine metabolism. Probably just wants his name in the history books...
Term
Gigantothermy
Definition
Large size helps to reduce body heat loss simply because are is squared and volume is cubed
Term
Heterometabolism
Definition
Switching between brady and tachy metabolism. Ex: Sharks in frenzy, Python during brooding
Term
K/T Extinction
Definition
65 million years ago. Likely due to climate change, volcanic overactivity and asteroid impact
