Thecodontosaurus was a herbivorous dinosaur that lived during the Triassic period. It had blunt, serrated teeth and ate low-lying plants like cycads and palms, though it may have also eaten some meat. Thecodontosaurus was bipedal but could also walk on all fours, had five fingers and toes, and grew up to 2.1 meters long and 1.2 meters tall.
