The Carnian Pluvial Episode, a major climate change event that occurred around 234 to 232 million years ago (Late Triassic epoch), was a time of global environmental changes and possibly substantial volcanism.
A new analysis of paleontological data suggests that this event was a major — but previously neglected — time of extinction and may be linked to the disappearance of up to 33% of all marine genera (invertebrates, vertebrates, and protists) as well as many tetrapod clades and to the explosive diversification of many key modern groups of plants and animals (conifers, insects, dinosaurs, crocodiles, lizards, turtles, and mammals).
