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 ...

Researchers have uncovered evidence of what led to the Triassic-Jurassic extinction about 201.6 million years ago. Columbia Climate School researchers suggest that sudden volcanic winter was the real ...

Deposits in Morocco associated with the Triassic-Jurassic mass extinction, 201.6 million years ago. Red sediments in many locations around the world contain Triassic-era fossils. The white band on top ...

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 ...

The Triassic–Jurassic transition represents one of Earth’s most profound episodes of biological upheaval, characterised by extensive volcanic activity, rapid climatic shifts and cascading ...

in Earth’s oceans, and, on land, most non-dinosaurian archosaurs, most therapsids, and the last of the large amphibians? Whatever it was, it shot down much of the competition so dinosaurs could later ...

Our planet’s first known mass extinction happened about 440 million years ago. Species diversity on Earth had been increasing over a period of roughly 30 million years, but that would come to a halt ...

A mass extinction about 200 million years ago, which destroyed at least half of the species on Earth, happened very quickly and is demonstrated in the fossil record by the collapse of one-celled ...

Earth has a long and dramatic history, and one recurring theme is extinction. Did you know that over the last 500 million years, our planet experienced five major mass extinction events? These events ...

There have been five unquestionably great extinctions on earth: the end-Ordovician, the late-Devonian, the end-Permian, end-Triassic, and the end-Cretaceous extinctions. Some think we are now in a ...
