Chialingosaurus was a genus of dinosaurs from the stegosauria group .
features
Chialingosaurus was a rather small stegosaur that reached a length of around four meters. Like all stegosaurs, it had a double row of bony structures (osteoderms) along the back and tail. They were small bone plates, the exact shape and size of which is not known.
The skull was tall and narrow and characterized by the small number of teeth compared to other stegosaurs. As with all stegosaurs, these were small and triangular and adapted to plant food. As with most stegosaurs, the hind legs were significantly longer than the front legs, but the comparatively slender limbs are characteristic of this genus.
Discovery and naming
Fossils of chialingosaurus were in the 1950s in the Shaximiao lineup in the Chinese province of Sichuan discovered and (actually from the famous Chinese paleontologists C. C. Young Yang Zhongjian ) scientifically described . The only species and therefore type species is C. kuani . The name of this dinosaur is derived from the Chialing (Jialing) River , a tributary of the Yangtze . The finds are dated in the Upper Jurassic ( Oxfordian ) and thus to an age of about 163 to 157 million years.
It was the first representative of the stegosauria to be found in China - meanwhile a number of genera, also from the same formation, are known from this country.
