By about 200 million years ago, this supercontinent began breaking up. Today, the theory of continental drift has been replaced by the science of plate tectonics.

It assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago. Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to 273 million years ago). The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present. 5 When did the supercontinent Pangaea begin to break apart?
