The Bahia Group, also known as Bahia Series, is an Early Cretaceous geologic group of the Recôncavo Basin in Bahia, Brazil dating back to the Valanginian and Hauterivian. Dinosaur remains are among the fossils that have been recovered from unit, including those of the ornithopod Tietasaura from the Marfim Formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. The conglomerates were deposited in an estuarine environment.Pedra Furada Bay at Fossilworks.org
