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.^[1] The formation is overlain by the Slogget and San Julián Formations and overlies the Divisadero and Kachaike Formations.^[2] Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.^[3]

• Clasmodosaurus spatula - Teeth^[4] - (sauropod indet)
• "Loncosaurus argentinus" (ornithopod indet.) - Femur.^[5] This genus may have also been found in the Matasiete Formation.
