酷東西

趣味知識

Auroraceratops had a short, wide snout, unlike many other early horned dinosaurs that had long, narrow snouts.1

Its name honors Dawn Dodson, the wife of paleontologist Peter Dodson, as well as meaning 'dawn horned face'.1

Over 80 skeletons of Auroraceratops have been found, many curled up as if they died in burrows.1

This dinosaur had rough, bumpy areas on its skull and jaws that were probably covered in horny material (keratin) in life.1

Auroraceratops lived in a seasonally dry environment alongside other dinosaurs like the tyrannosauroid Xiongguanlong and the ornithomimosaur Beishanlong.1

It was about the size of a large dog, only 1.25 meters (4.1 feet) long and weighing about 15.5 kilograms (34 pounds).1
