Heterodontosaurus

名字的意思： “different-teeth lizard”1

吃：植物有喙的草食恐龍侏羅紀早期

Heterodontosaurus was a tiny, speedy dinosaur that lived in the Early Jurassic. It had three kinds of teeth, just like some mammals today, and a beak at the front of its mouth. This little plant-eater could run fast to escape bigger predators.1

趣味知識

Heterodontosaurus means 'different-teeth lizard' because it had three types of teeth: small incisors, tall canine-like teeth, and grinding cheek teeth.1

This dinosaur lived about 205 million years ago, during the Early Jurassic period.1

Heterodontosaurus was only about 1.2 metres (4 feet) long, about the size of a large dog.1

It had a horny beak at the front of its mouth, like a bird or turtle, to help it bite off plants.1

Fossils of Heterodontosaurus have been found in South Africa and Lesotho, and one possible fossil came from Mexico.4 1

Scientists think Heterodontosaurus could run quickly on its long hind legs to escape predators.1
