| Abstract: | A new carnosaur of the family Megalosauridae (Reptiles, Saurischia) is described. It came from Lower Shaximiao Formation (Middle Jurassic) of Xuanhan County in the Siehuan Basin, Southwestern China and is named as Xuanhanosaurus qilixiaensis gen. et sp. nov. This is a medium sized theropod with a total body length of about 6 m. The forearm is relatively massive and long. The humerus is straight, and has a medial deltopectoral crest. The ratio of maximum length of humerus to radias is 1.3. It is extremely conservative for a carnosaur. The metacarpal Ⅲ is comparatively massive and metacarpal Ⅳ short and light. |
