酷東西

趣味知識

Chungkingosaurus had a thagomizer with two pairs of stout spikes and an extra pair of long, thin spikes at the very tip of its tail.1

It was one of the smallest stegosaurs, with an adult skeleton less than 4 metres long.1

Its back plates looked like modified spikes, with a thickened middle section.1

Chungkingosaurus lived alongside other plant-eaters like Tuojiangosaurus and Mamenchisaurus, and might have been hunted by the meat-eater Yangchuanosaurus.1

Some scientists think Chungkingosaurus might be a juvenile of Tuojiangosaurus, but others disagree.1

The first fossils were found near Chongqing, China, starting in 1977.1
