Broome Sandstone

The Broome Sandstone, formerly known as the Broome Beds, is an Early Cretaceous geologic formation found in Western Australia, and formerly considered part of Dampier Group. Fossil sauropod tracks, belonging to an unknown ichnotaxon, and stegosaur tracks belonging to the ichnogenus and species Garbina roeorum have been reported from the formation since the 1990s.^[2][3][4]
