Dinosaurs - Geographic Range

The Earth that the early dinosaurs knew looked much different than the Earth does today. The planet had a single, huge land mass, called Pangaea, and the dinosaurs lived over much of this area, particularly in the warmer climates. About 180 million years ago—50 million years after the dinosaurs first evolved—Pangaea began to split up and eventually formed the continents seen on Earth today. Given such huge changes, a fossil found nowadays in Germany, for example, says nothing about the location of the dinosaur that left it 220 million years ago.
