Dinosaurs

Dinosaurs lived only during the Mesozoic Era, which is often called the “Age of Dinosaurs.” Utah has perhaps the best Mesozoic rock record in the world. The Mesozoic Era (225 to 65 million years ago) is divided into three time periods: the Triassic (225-193 million years ago); the Jurassic (193-136 million years ago); and the Cretaceous (136-65 million years ago).
