Continental Drift - 190 Million Years Ago

190 Mya

By 190 million years ago, the end of the Triassic period and the beginning of the Jurasic, a great rift had opened between northern and southern Pangea and the Tethys Sea had separated the two primary land masses. North America and Eurasia formed the nor thern land mass and South America, Africa and the remaining continents formed the southern mass. The southern land mass was beginning to break up itself and Antarctica, Australia and India were going their separate ways.

Large plant eating dinosaurs roamed the continents feeding on ferns and palm-like cycads and they were in turn fed upon by smaller carnivorous dinosaurs. The oceans were now full of fish and squid and the trilobites had become extinct. Early mammals were roaming the forest floors and the first birds had also appeared.
