Sclerorhynchid teeth (Neoselachii, Sclerorhynchidae) from the Late Cretaceous of the Quiriquina Formation, central Chile

Mario E. Suarez, Henri Cappetta

Abstract


The rostral tooth morphology of Ischyrhiza chilensis (Philippi, 1887) is examined on the basis of a new material from the Maastrichtian of the Quiriquina Formation, central Chile. Oral teeth of a new sclerorhynchid, Biropristis landbecki gen. et sp. nov., are described from the same formation of the Algarrobo locality. These discoveries provide new and important data on the diversity and the paleobiogeography of Sclerorhynchidae, still poorly known in the Pacific realm of the southern hemisphere.
