Also known as Elaltitan lilloi type

Where: Chubut, Argentina (45.5° S, 68.9° W: paleocoordinates 52.1° S, 46.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Lower Member (Bajo Barreal Formation), Middle Cenomanian to Middle Cenomanian (99.6 - 89.3 Ma)

• Lower member of the Bajo Barreal Formation (Bonaparte, 1996; Bridge et al., 2000; Lamanna et al., 2002; Powell, 2003; Martinez et al., 2004); middle Cenomanian–Turonian (Archangelsky et al., 1994; Bridge et al., 2000; Lamanna et al., 2002). Bonaparte and Gasparini (1979) originally listed this specimen as having come from the Laguna Palacios Formation. However, this proposed provenance has been doubted by subsequent authors and, most significantly, the Laguna Palacios Formation does not crop out in this region (Bridge et al., 2000); therefore, the attribution of the specimen to the Bajo Barreal Formation seems secure.
