Lagarcito Formation

The Lagarcito Formation is an Albian geologic formation in Argentina. Pterosaur fossils have been recovered from the formation. The formation overlies the La Cruz Formation and is overlain by the San Roque Formation. The sandstones and mudstones of the formation were deposited in a fluvial and mostly lacustrine environment. The fossil association and the geological evidence indicate that the Lagarcito Formation represents a perennial shallow lake situated in an alluvial plain where detrital sedimentation and semiarid climatic conditions predominated.
