A Shunosaurus defending itself against a Kaijiangosaurus. (*)
Kaijiangosaurus (meaning "Kiijiang lizard", in reference to the area where it was found) is the name given to a genus of dinosaur from the Middle Jurassic. It was a theropod like Megalosaurus. Its fossils, partial vertebrae, were found in China.
The type species, K. lini, was described by He in 1984. It may actually be Gasosaurus. Indeed, Gasosaurus was found in the same formation as Kaijiangosaurus, the Lower Shaximiao Formation section of the Dashanpu Formation.
