Dark Brandon did this...no wait...

 

A quote from "Arctic ice and the ecological rise of the dinosaurs" by Paul Olsen et al. 

>>>Even as it has become clear that many dinosaurs were insulated with protofeathers, the idea that non-avian dinosaurs were predominately denizens of warm climates in an ice-free high PCO2 hothouse Mesozoic world has persisted. 

>>>It is now apparent here based on empirical evidence (rather than just models) that freezing temperatures occurred seasonally at high latitudes during the Late Triassic and Early Jurassic despite exceptionally high PCO2. Being primitively insulated, dinosaurs were able to take advantage of the rich plant resources in the high latitudes. 

>>>Through their adaptation to cold temperatures, dinosaurs were able to survive the CAMP volcanic winters and thereby expand to dominate terrestrial communities for the next 135 Ma, and, as birds, remain two to three times more speciose than mammals to this day.

Hmmm...

Wat means?
