吃：植物有喙的草食恐龍侏羅紀晚期到白堊紀早期

Chilesaurus was a small, plant-eating dinosaur that lived in Chile about 150 million years ago. It had a beak like a bird and teeth shaped like leaves for slicing plants. Scientists were surprised to find that it was a plant-eater because its body looked a lot like a meat-eater's.2

趣味知識

Chilesaurus was first discovered by a seven-year-old boy named Diego Suárez in 2004. The species name 'diegosuarezi' honors him.2

It had a beak at the front of its mouth, similar to a bird's beak, which it used to crop plants.1

Chilesaurus walked on two legs and had a long tail to help it balance.2

Its hips looked like those of a bird-hipped dinosaur, such as Stegosaurus or Triceratops, even though its body was built like a meat-eater.2

Scientists think Chilesaurus is a 'missing link' between meat-eating dinosaurs and early plant-eaters.2

Chilesaurus lived during the Late Jurassic Period, about 150 million years ago.2

迷思破解王

迷思： Chilesaurus was a meat-eating dinosaur because it had a body like a theropod.

真相： Chilesaurus was actually a plant-eater. Its teeth and jaws were adapted for slicing plants, not meat.2
