Summary:

The Camarones Sandstone, here named, was included in the Hato Puerco Tuff by previous writers. Consists of well-bedded, calcareous, dark-gray, thin-bedded tuffaceous siltstone interstratified with tuffaceous wacke and conglomerate. Includes the Mamey Lava Member. Base is indeterminate; interfingers with the Santa Olaya Lava; conformably underlies the Tortugas Andesite. Stratigraphically equivalent to the Rio de la Plata Sandstone. Maximum thickness is 680 m. Age is Late Cretaceous (Coniacian).
