At the end of the day, though, Olsen defends this event as a legitimate mass extinction. If you look over thousands of feet of rock strata above and below it, encompassing tens of millions of years on ...

You will find this mass extinction event referred to in a few different ways including the end-Triassic mass extinction (ETME) and Triassic-Jurassic (Tr-J) extinction event (TJME).

By about 200 million years ago, however, dinosaurs had essentially taken over the planet, while most other reptiles disappeared during the end-Triassic extinction.

Instead, he argues that we should aim to prevent human-induced extinction from hitting 0.2 per cent of species – a far cry from the 75 per cent needed to qualify for a mass extinction, and the ...

The Idaho ecosystem flourished 1.3 million years later, "quite rapid on a geological scale," according to Brayard. Complex epoch The mass extinction's cause is a matter of debate.
