''Eoborus'' is the oldest fossil record of Strophocheilidae, dating from the Middle Paleocene of Brazil (Itaboraí Basin)〔Salvador, R.B. & Simone, L.R.L. 2012. New fossil pulmonate snails from the Paleocene of Itaboraí Basin, Brazil (Pulmonata: Cerionidae, Strophocheilidae, Orthalicidae). Archiv für Molluskenkunde 141(1): 43-50. 〕 and Uruguay (Santa Lucía Basin).〔Martínez, S.; Veroslavsky, G.; Verde, M. 1997.
