The Mesozoic era was the time of dinosaurs like the triceratops and the velociraptor. Many dinosaurs were strong but there was only one that was what most people call the king, the T-Rex
At the beginning of the Mesozoic Era, all of the earth's continents were welded together to form the supercontinent Pangaea. This hot and dry continent was inhabited by reptiles that had survived the Permian–Triassic extinction event. Near the end of the Triassic Period, Pangaea began to break apart.
