Late Jurassic ichthyosaurs are well represented in the Tithonian of the Neuquén Basin, in northwestern Patagonia, Argentina. Most of the ichthyosaur material from the Neuquén Basin was originally identified as Ophthalmosaurus. Recently, the new ichthyosaur Caypullisaurus was described based on an almost complete mature specimen from Cerro Lotena. Some material previously referred to Ophthalmosaurus has been referred to the new genus. However, both genera are present in the Tithonian of the Neuquen Basin. The discovery of an articulated forefin in Cajón de Almanza (Neuquén, Argentina) confirms the presence of Ophthalmosaurus in the uppermost Tithonian of the Neuquén Basin
