Triassic–Jurassic extinction event

E201672
geological boundary event mass extinction event paleontological event

The Triassic–Jurassic extinction event was a major mass extinction around 201 million years ago that wiped out many marine and terrestrial species, paving the way for dinosaurs to become the dominant land animals in the Jurassic Period.
