Dinocephalosaurus is a genus of long necked, aquatic Archosaurs which lived in the Triassic seas. Its fossils are found in 244 ± 1.3 million year old rocks.
Didocephalosaurus means "terrible headed lizard". The first specimen found was just a skull, discovered near Xinmin in Guizhou Province, China in 2002. The second specimen found nearby, and was the head and much of the postcrainal skeleton, minus the tail. Dinocephalosaurus is the "first record of protorosaurid reptile (Order Protorosauria) from the Middle Triassic of China".
A new specimen found in Yunnan Province, southern China, showed evidence of live births (ovoviviparity). This is the earliest known example of this in the large group of tetrapods which includes dinosaurs, crocodiles, pterosaurs and birds.
