4. How the Triassic-Jurassic Mass Extinction Gave Rise to the Dinosaurs

Welcome back everyone to the Great Dyings, a five-part video series on the five mass extinctions. Last time we explored the most deadly extinction event in the history of life: the Permian-Triassic mass extinction that ended the Paleozoic era and began the Mesozoic era with the Triassic period. Today, we will explore the Triassic-Jurassic mass extinction, which ended the Triassic on the Triassic-Jurassic border. While it is a relatively unknown extinction, the Triassic-Jurassic mass extinction is incredibly significant since it paved the way for the age of the dinosaurs.
