Tuojiangosaurus

The Tuojiangosuarus was a species that lived in what is now China. Related to the North American Stegosaurus, the Tuojiango had triangular spines instead of pentagons. Due to a difference in hip structure the Stegosaurus is thought to have been able to stand up on its hind legs while its Chinese cousin could not.

Just look at this Jaunty Boi and his friends, though. They don't need to stand up on their hind legs when they can have this much fun on all fours <3
