Earth's first giant plant-eater β€” Plateosaurus ruled Europe long before most dinosaurs existed!

KindDinosaur Period Triassic Diet Herbivore

Plateosaurus roamed the Earth long before many of its cousins and was among the first of the larger dinosaurs to be discovered. A prosauropod, Plateosaurus is a relative of the giant sauropods, like Diplodocus. This dinosaur lived in Europe about 200 million years ago, when the climate there was hot and arid, like a desert.

Plateosaurus lived during the Late Triassic period, before most other dinosaurs. This large plant-eater was about twenty-six feet long and could stand on its hind legs to reach leaves high in trees.

Hand or Foot?

Hand or Foot?

We know this Plateosaurus fossil is a "hand" because of the sharp, narrow claws used for holding things, or for tearing leaves off trees. Plateosaurus fed on plants at ground level on all fours, and then reared up on its hind legs to reach the treetops. The joints between the bones allowed the hand to be bent back at the "wrist" when Plateosaurus walked on all fours.

Leaves for Lunch

Leaves for Lunch

Plateosaurus probably ate leaves, shredding some of them with its rows of small teeth, and others with stomach stones in its gizzard. Maybe it used its sharply-clawed front legs to gather food or to defend itself.

Death by Drowning?

The skeletons of many Plateosaurus dinosaurs have been found at Trossingen, Germany. Many of these fossils are found in groups, which may suggest that they traveled in herds. Perhaps they were caught in a flash flood, or they may have died after getting stuck in a muddy bog.
