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.
