Cardiel Formation (Argentina)

The Cardiel Formation is a Maastrichtian geologic formation of the Austral Basin in Santa Cruz Province, Argentina. The formation comprises sandstones and conglomerates with abundant tuff beds. The formation is overlain by the Slogget and San Julián Formations and overlies the Divisadero and Kachaike Formations. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
