Triassic Period

Earth was a very different place at the beginning of the Triassic. All of Earth's continents were combined into one supercontinent called Pangaea. And over 95% of the world's species became extinct in the largest mass extinction ever in history. A lot would change over the next 50 million years. Pangaea began to spread apart, and surviving species spread out and diversified as new ones evolved, including the first dinosaurs.
