The La Pedrera de Rúbies Formation, also called as La Pedrera de Meiàis an Early Cretaceous (late Berriasian to early Barremian geologic formation in Catalonia, Spain. The formation crops out in the area of the Montsec in the OrganyàBasin. At the La Pedrera de Meiàlocality, the formation consists of rhythmically laminated, lithographic limestones that formed in the distal areas of a large, shallow coastal lake. It is noted for the exceptional preservation of articulated small vertebrates and insects, similar to that of the Solnhofen Limestone.
