酷東西

趣味知識

Yamaceratops was about as long as a cat, only 50 cm (1.6 ft) from nose to tail.1

A juvenile Yamaceratops was found that was about three years old and weighed only 1.2 kg (2.6 lb).1

Its name comes from Yama, a Tibetan Buddhist god, and 'ceratops' meaning horned face.1

Yamaceratops had long hind legs, which means it probably ran on two feet.1

The frill on its head was not for display, unlike later horned dinosaurs. Scientists think it may have been used for something else.2

It lived during the Late Cretaceous, about 85 to 72 million years ago.3
