The Lotena Formation is a geologic formation dated from the Late Callovian to Early Oxfordian in the Neuquén Basin in Mendoza Province, Argentina.[1] The formation, first defined by Weaver in 1931 and named after Cerro Lotena,[2] consists of fluvial conglomerates, calcareous sandstones and marine limestones and shales.[2][3] The Lotena Formation is overlain by the La Manga Formation and overlies the Lajas Formation of the Cuyo Group.[4] Initially, the fossil find of the pterosaur Herbstosaurus pigmaeus was reported from the formation,[5] but this fossil was found in the younger Vaca Muerta.[6] The formation is a reservoir rock in the Neuquén Basin.
