What event ended the Triassic period?
What event ended the Triassic period?
Huge and widespread volcanic eruptions triggered the end-Triassic extinction. Some 200 million years ago, an increase in atmospheric CO2 caused acidification of the oceans and global warming that killed off 76 percent of marine and terrestrial species on Earth.
What was the end-Triassic extinction?
201.3 million years agoTriassic–Jurassic extinction event / Ended
Which period ended with the Permian-Triassic extinction event?
The Permian–Triassic (P–T, P–Tr) extinction event, also known as the End-Permian Extinction and colloquially as the Great Dying, formed the boundary between the Permian and Triassic geologic periods, as well as between the Paleozoic and Mesozoic eras, approximately 251.9 million years ago.
What are the 5 mass extinction events?
Top Five Extinctions
- Ordovician-silurian Extinction: 440 million years ago.
- Devonian Extinction: 365 million years ago.
- Permian-triassic Extinction: 250 million years ago.
- Triassic-jurassic Extinction: 210 million years ago.
- Cretaceous-tertiary Extinction: 65 Million Years Ago.

What were the major events in the Triassic period?
During the Triassic, the first dinosaurs walked on the land, the first pterosaurs sailed through the skies, and the first ichthyosaurs and plesiosaurs swam in the oceans. The lineage of many modern-day reptiles began in the Triassic Period, including crocodiles, lizards, and turtles.
What species survived the end-Triassic extinction?
All major groups of marine invertebrates survived the extinction, although most suffered losses. Brachiopods, shelled cephalopods, sponges and corals were particularly hard hit. On land, casualties included the phytosaurs, a group of crocodile-like animals.
What ended the Permian period?

Why did the Permian Period End?
New research shows the “Great Dying” was caused by global warming that left ocean animals unable to breathe. The largest extinction in Earth’s history marked the end of the Permian period, some 252 million years ago.
