The mass extinction that wiped out nearly all life on Earth just before the dinosaurs evolved may have been caused by a global temperature drop rather than a rapidly warming climate. The End Triassic ...

The Jurassic Period is one of the three prehistoric geological periods of the Mesozoic Era. It spans from 145 million to 201 million years ago. This period was preceded by the Triassic Period and ...

Everyone knows about the mass extinction that ended the Age of Dinosaurs. About 66 million years ago, a seven-mile-wide asteroid slammed into our planet and began a mass extinction that wiped out all ...
