| Abstract: | A new megalosaur, Gasosaurus constructus gen. et sp. nov., is described primely in this note. The type obtained from a large sandstone block is an incomplete skeleton including 4 cervical, 7 dorsal, 5 sacral, 7 caudal, part of limb and left pelvic girdle. The paratype is three teeth. The materials came from the dinosaurian quarry of Dashanpu, Zigong, Sichuan Basin. The age is considered as Middle Jurassic. The new form is a small megalosaur attaining a length approximately 3.5 m. The teeth are megalosaur-like in shape. The cervical is platecoelus with incipient weak ventral keel. The sacrum consists of five firnfly fused sacral vertebrae, the neural spines of which are not fused. The distal end of pubis and ischium form a rather expandjng process without a "foot". |
