Chialingosaurus (meaning "Chialing Lizard") was a type of stegosaur similar to Kentrosaurus from the Upper Shaximiao Formation, Late Jurassic beds in Sichuan Province in China. Its age makes it one of the oldest species of stegosaurs, living about 160 million years ago. Since it was an herbivore, scientists think that Chialingosaurus probably ate ferns and cycads, which were plentiful during the period when Chialingosaurus was alive. Its name is taken from the Chialing River in southern China. Perhaps growing up to 13 ft (4m) long and weighing just 330 pounds (150 Kg), much less than other later stegosaurs.
[edit] Discovery and species
Collected by the geologist Kuan in 1957 in Quxian county, the dinosaur was named by paleontologist C. C. Young two years later, although only very incomplete fossilized remains of the Chialingosaurus have been found. In 1969, Rodney Steel suggested that Chialingosaurus might have actually been an early ancestor of other stegosaurs, but it is difficult to tell: the type specimen, Chialingosaurus kuani is known from only one partial skeleton. The original material having been supplemented in 1978 by Zhou of the Municipal Museum of Chongqing.
