The Triassic was the first period of the Mesozoic Era, the Age of Reptiles. Unlike the following Jurassic and Cretaceous periods, dinosaurs were not yet the dominate animals during the Triassic Period. The purpose of this video is to provide an extensive summary of these early dinosaurs, which were quiet different from the view most people have of the dinosaurs.

It covers both the most famous dinosaurs of this time, such as Coelophysis and Plateosaurus, and much more obscure ones like Daemonosaurus and Saturnalia. It also gives an overview of their spread across Pangea, their early evolution, and of course their rise to dominance.

Thank you to the themattalorian for narrating this video and to Bethany Lester (@bethssketches) for creating the illustration depicting Triassic dinosaurs in a snowy environment.
