Chota Formation

The Chota Formation is an Early Campanian to Late Eocene geologic formation of the Cajamarca and western Amazonas Region in northern Peru. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus ("Baguasaurus").[1] The formation was formerly named Bagua Formation.[2]
