Shunosaurus was a plant-eating dinosaur with a long neck and a secret weapon on its tail. It lived in what is now China during the Late Jurassic period, about 161 to 157 million years ago. This dinosaur was one of the most common animals in its home, making up 90% of the fossils found there.1

Fun facts

Shunosaurus had a very short neck for a sauropod, similar to some other dinosaurs called dicraeosaurids.1

Its tail ended in a club with two spikes made of bone, each about 5 centimetres (2 inches) long. It probably used this club to fight off predators.1

Scientists know a lot about Shunosaurus because many complete skeletons, skulls, and even babies have been found. About 94% of all its bones have been identified.1

Shunosaurus was first discovered in 1977 by a group of students practicing fossil digging at a road bank in Dashanpu, Sichuan.1

Its teeth were strong and long, with crowns up to 8 centimetres (3.1 inches) long. They had a unique shape: a cylindrical body with a spoon-shaped tip.1

Shunosaurus lived alongside other dinosaurs like the sauropods Datousaurus and Omeisaurus, the early stegosaur Huayangosaurus, and the meat-eating theropod Gasosaurus.1
