Segnosaurus

名字的意思： “slow lizard”1

吃：植物奇特的羽毛恐龍白堊紀晚期

Segnosaurus was a big, slow-moving dinosaur with a small head, a long neck, and huge claws on its hands. It used its beak to nibble plants and its big belly to digest them. Unlike most meat-eating dinosaurs, this one was a gentle giant that ate only plants.1

酷東西

趣味知識

Segnosaurus had four toes on each foot, while most other meat-eating dinosaurs had only three.1

Its name means 'slow lizard' because scientists thought it was a slow-moving animal.1

Segnosaurus lived about 102 to 86 million years ago in what is now Mongolia.1

It had a horny beak at the tip of its jaws, like a bird, to help it eat plants.1

Some of its teeth had extra ridges and even a third cutting edge, which is unusual for a plant-eater.1

Segnosaurus was probably covered in simple, fluffy feathers, like its relatives Beipiaosaurus and Jianchangosaurus.1
