Lufengosaurus, (Chinese: 祿豐龍 or 禄丰龙, meaning "Lufeng Lizard"), was a prosauropod dinosaur which lived during the Early 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.

[edit] Discovery and species
Named by C.C. Young in 1941, remains of the type species, L. huenei, were found in the Lower Lufeng Formation (Lower Jurassic) of Yunnan Province in China. A second species was named by Young a year later. L. magnus was, as its name suggests, a significantly (up to 1/3rd) larger creature than L. huenei.
Lufengosaurus species
- L. huenei
- L. magnus
[edit] Classification
In 1981, Cooper[1] suggested Lufengosaurus and Yunnanosaurus were species of the South African genus Massospondylus. However, a recent reanalysis[2] of the skull of Lufengosaurus huenei establishes it as a distinct genus separate from either Massospondylus or Yunnanosaurus.
[edit] Palaeobiology
Like all prosauropods, Lufengosaurus had much longer hindlimbs than forelimbs and was probably bipedal some of the time, especially when browsing for food. It was herbivorous, although 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, but the sharp teeth witnessed in Lufengosaurus and other prosauropods are similar to those seen in iguanaian lizards - which are herbivorous [3]. Alternatively, the claws may have been used for defense or raking foliage from trees.
[edit] Popular Culture
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.
