The Colalura Sandstone is a Middle Jurassic geologic formation of the Perth Basin of Western Australia. The formation overlies the Moonyoonooka Sandstone.
Dinosaur remains have been recovered from the formation.
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.
