New specimens of Aturia (Nautilida) were collected from the late Eocene to early Oligocene deposits of the San Jacinto Formation near Ovejas (Sucre, northern Colombia). These specimens, alongside historical material collected from a nearby region, are identified as Aturia peruviana. The morphological analysis of the shell (the phragmocone and suture line characters) confirms that Aturia colombiana is a junior synonym of A. peruviana, in conformity with previous taxonomic proposals. Furthermore, the stratigraphic range of A. peruviana in Colombia is constrained to the upper Eocene to lower Oligocene, consistent with its documented occurrence in Peru.
