Tuojiangosaurus (Tuojiangosaurus multispinus) was a dinosaur of the Late Jurassic period that existed about 155 million years ago. It was first thought to have belonged to the Stegosauridae family, with quite a few similarities to the Kentrosaurus dinosaurs. The skeletal remains of this dinosaur were excavated from the Sichuan Province, China.

They had a bulky body with an average weight of 4 ton (3629 kg). The back of these dinosaur species consisted of narrow spikes that extended till the long tail.

The spines on the back probably helped them in thermoregulation or for defending themselves from the potential threats. Their skull specimen reveals to us that they had powerful jaws along with strong teeth.

They followed a herbivorous diet and foraged on a wide array of plants. Researchers also claimed that this dinosaur species could not rear up on their hind legs, and therefore, they were low-lying eaters that mainly foraged on the ground.

Read on to learn more fun facts about this dinosaur.
