The Colalura Sandstone is a Middle Jurassic geologic formation of the Perth Basin of Western Australia. The formation overlies the .^[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]
