酷東西

趣味知識

Eoraptor had 4 teeth in the upper front of its mouth and 18 in the upper cheek, a mix that helped it eat different foods.1

Unlike later meat-eaters, Eoraptor could not bend its lower jaw to hold big prey, so it probably ate small animals and plants.1

Its name means 'dawn plunderer' because it lived at the dawn of the dinosaur age and had grasping hands.1

Eoraptor lived in a warm, humid place with ferns and giant conifers, alongside other early reptiles and dinosaurs.1

The first Eoraptor fossil was found in 1991, and it took almost a year to carefully dig out of the rock.1

Scientists think Eoraptor was a fast runner, using its long legs to sprint after prey.1
