Fossil record The fossil record of Plagiodontes extends back to the Brazilian Paleocene, with a supposed specimen of Plagiodontes dentatus found in 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. This same species has also been recorded from the Miocene of Uruguay and Miocene and Pleistocene of Argentina.Caorsi J. & Goñi J.C. 1958. Geologia Uruguaya.
