The Colalura Sandstone is a Middle Jurassic geologic formation of the Perth Basin of Western Australia. The formation overlies the Moonyoonooka Sandstone.[2]
Dinosaur remains have been recovered from the formation.[3]
Vertebrate paleofauna
Few remains of the sandstone have been assigned to a genus. Unassigned remains include rare reptilian bones such as an isolated plesiosaur vertebra and paddle.[1]

| Ozraptor | O. subotaii | Western Australia | The distal end of a tibia[1][3] | The single bone is of a questionable theropod identity.[4] | ||

Flora
Petrified wood is very common in the Colalura Sandstone.[1]
