酷東西

趣味知識

Jianchangosaurus had wide, unbranched feathers on its neck that may have been used for display, like a peacock's tail.3 2

It is one of the most complete therizinosaur skeletons ever found, missing only the tip of its tail.3

Its teeth were set in a shelf-like jaw, similar to some plant-eating dinosaurs like ornithopods and ceratopsians.3

Jianchangosaurus was about 2 meters (6.6 feet) long and stood 1 meter (3.3 feet) tall at the hips.2

It lived during the Early Cretaceous period, between about 125 and 119 million years ago.1

The fossil was found in the Yixian Formation in China, a famous site for feathered dinosaurs.3 1

Yes, it was a theropod dinosaur, specifically a therizinosaur.2 4

迷思破解王

迷思： Jianchangosaurus was a meat-eater because it is a theropod.

真相： Although it belongs to the theropod group, Jianchangosaurus had a beak and teeth suited for eating plants, and scientists now think it was a herbivore.2 1
