The Buena Vista Formation is a Late Permian-Early Triassic geologic formation of the Cerro Largo Department in northeastern Uruguay. The fluvial sandstones and mudstones preserve temnospondyl and archosaur fossils.
Description[edit]
The Buena Vista Formation is characterized by reddish fine sandstone interbedded with lenticular clay layers and intraformational conglomerates deposited in a fluvial environment.[1]
