In the Triassic Period, 248-208 million years ago, the dinosaurs began to evolve.
During the Jurassic Period - about 208-144 million years ago - the dinosaurs reached their greatest size. The Cretaceous Period is when dinosaurs were at their most varied - about 144 - 065 million years ago. In the Triassic Period, all the continents were joined in one supercontinent -
Pangaea. 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'. The joining and separating of the continents affected which kinds of dinosaurs lived where.
