The La Cruz Formation is an Aptian geologic formation in Argentina. Pterosaur fossils of Pterodaustro guinazui have been recovered from the formation.[1] The formation, the uppermost unit of the El Gigante Group, overlies the El Toscal Formation, and is overlain by the Lagarcito Formation. The unit comprises sandstones and conglomerates, deposited in an alluvial plain to fluvial environment.[2]
