A genus of stegosaurian from the Middle Jurassic, its name means Huayang lizard, referring to Huayang, an alternate name for the Chinese province of Sichuan, where it was discovered; its name also references the Hua Yang Guo Zhi, a Jin Dynasty gazatteer. The huayangosaurus was about 4.5 metres long (14 ¾’). Like most stegosaurians, it was a quadrupedal herbivore with a small skull, a spiked tail, and a double row of plates down its back. In huayangosaurus’s case, the plates were more like spikes than those on its (much later) relative, Stegosaurus. Unlike the later stegosaurians, the huayangosaurus had teeth in the front of its mouth.
According to the Audubon Society’s Familiar Dinosaurs, the huayangosaurus may have stood on its hind legs occasionally to browse choice vegetation.
