Information About Dinosaurs

Hi Everyone,
Information on History of Dinosaurs:
  • The Age of Dinosaurs corresponds to the time that geologists call the Mesozoic Era, from about 248-65 million years ago.
  • The Mesozoic Era is divided into three shorter time spans: -- the Triassic, Jurassic, and Cretaceous Periods.
  • In the Triassic Period, 248-208 mya(million years ago), the dinosaurs began to evolve.
  • During the Jurassic Period --about 208-144 mya, the dinosaurs reached their greatest size.
  • The Cretaceous Period is when dinosaurs were at their most varied--about 144-65 mya.
  • In the Cretaceous Period, Laurasia and Gondwana split, and the continents as we know them began to form.
  • In the Mesozoic Era, the major land-masses gradually moved across the globe in a process known as "continental drift.
