Why Plant-Eating Dinos Might Have Avoided The Equator

It has long been known that large herbivorous dinosaurs did not populate tropical areas during the late Triassic Period, which was about 230 to 200 million years ago. But, oddly enough, no one knew why.
Well, according to a new study, it was the unstable climate that kept those herbivores from migrating to tropical areas.
As one of the researchers from the study put it, "Large, warm-blooded dinosaurian herbivores weren't able to exist close to the equator — there was not enough dependable plant food."
