[Machine Translation] The Triassic period began with the rise of reptiles. Some eventually took to the skies and became pterosaurs, while others moved into the sea and flourished as ichthyosaurs, ctenophorids, mosasaurs, and others. Finally, on the ground, dinosaurs began to flourish. Dinosaurs dominated the earth for more than 160 million years. However, one day, the competition among giant creatures of land, sea, and air came to an abrupt end.
