The Bahia Group, also known as Bahia Series, is an Aptian geologic group of the Recôncavo Basin in Bahia, Brazil. Dinosaur remains are among the fossils that have been recovered from unit, including those of the ornithopod Tietasaura from the Marfim Formation. The conglomerates were deposited in an estuarine environment.
