Lufengosaurus, (Loo-FUNG-oh-SORE-us) was a prosauropod dinosaur which lived from the Late Triassic to the Middle Jurassic period in what is now southwestern China.

At about 6 metres long, it was the first complete dinosaur skeleton mounted in China and a commemorative postage stamp was issued in 1958. Like all prosauropods, Lufengosaurus had much longer hindlimbs than forelimbs and was probably bipedal some of the time, especially when browsing for food. It is generally thought to be herbivorous, though it had sharp claws (with an especially large thumb claw) and teeth.

These features have been used to support claims that Lufengosaurus may have been at least partially omnivorous. Alternatively, the claws may have been used for defense or raking foliage from trees.

It grew to about 6 metres in length.

Lufengosaurus was the first dinosaur skeleton mounted in China. When the exhibit finally opened a stamp was issued with an image of Lufengosaurus on it.
