酷東西

趣味知識

Jinbeisaurus is the first non-bird theropod dinosaur ever named from Shanxi Province in China.1

Its name comes from 'jin' (short for Shanxi) and 'bei' (north), because it was found in northern Shanxi.1

The holotype specimen includes both upper jaw bones (maxillae), a partial lower jaw, neck and back vertebrae, and a hip bone.1

Jinbeisaurus lived during the Late Cretaceous period, between about 100 and 72 million years ago.3

Scientists think Jinbeisaurus was more advanced than earlier tyrannosauroids like Suskityrannus and Xiongguanlong, but not as advanced as the true tyrannosaurids.1

Some researchers now think the Jinbeisaurus fossil might be from a young animal, not a full-grown adult.1
