The Mercedes Formation is a Late Cretaceous (Campanian to Maastrichtian) geologic formation of the Norte Basin in Uruguay. Fossil dinosaur eggs have been reported from the formation.Weishampel et al., 2004, pp.517-607 The formation that reaches a thickness of about {{convert|100|m|ft}},Tofalo et al., 2011, p.616 overlies the Guichón Formation and is overlain by the Asencio Formation.Tofalo et al., 2011, p.617
