List of Dinosaur genera that survived the Triassic-Jurassic Extinction Event 201 Million Years ago

March 27

The Triassic-Jurassic Extinction Event of 201 Million Years ago is less talked about at times than the Mass Extinction events at the end of the Permian and the end of the Cretaceous, but was still an incredibly significant extinction event in Earth’s geologic history.

Caused by volcanic eruptions that would eventually break apart Pangea and form the Atlantic Ocean, about 23-43% of marine genera (including 96% of coral genera at the time) was wiped out alongside between 17-73% of plant genera at the time. On land, archosaur diversity was decimated. Phytosaurs, Aetosaurs, and many others primitive archosaur groups were wiped out. But one major group of archosaurs that survived were the dinosaurs (Dinosauria). Emerging first in the middle Triassic, dinosaur diversity was hit hard by the event. But the group was overall able to survive thanks to adaptations such as a mostly warm-blooded metabolism and (for theropod dinosaurs) feathers for warmth. Some of the first true mammals including Morganucodon also survived the event, but they would take more of a backseat until the end of the Mesozoic era. For the Dinosaurs, the survivors of the event would go on to diversify, increase in size, and dominate Earth’s terrestrial ecosystems for the next 135 Million Years as they become one of the most successful animal groups in Earth’s history. Here’s a list of all currently known Dinosaur genera and families that survived the Triassic-Jurassic Extinction Event.

If I forget any examples, please let me know and I'll add the examples to the list promptly.
