Table 5. Fossil vertebrate fauna of the Upper Cretaceous (Cenomanian—Turonian) Bajo Barreal Formation of central Patagonia, Argentina.

Note that several taxa previously assigned to this formation (e.g., the titanosaurian sauropods Aeolosaurus colhuehuapensis, Argyrosaurus superbus, and Elaltitan lilloi; the hadrosaurid ornithopod Secernosaurus koerneri) are now known to come from a recently defined, stratigraphically younger geologic unit, the Lago Colhué Huapi Formation [80].
