Resumen:
The present paper reports the first paleoparasitological results obtainedfrom coprolites of fossil rodent middens and demonstrates the potential ofrodent middens as a source of paleoparasitological evidences in SouthAmerica. Ten fossil rodent middens from northwestern Patagonia, Argentina,were studied. Five coprolites of each midden were fully processed, rehydrated,homogenized, subjected to spontaneous sedimentation, and examined throughlight microscopy. Eight of the 10 examined rodent middens contained parasiteeggs. The eggs of parasites were assigned to Heteroxynema (Cavioxyura)viscaciae Sutton & Hugot, 1989 and Helminthoxys sp. (Nematoda: Oxyuridae),Trichuris sp. (Nematoda: Trichuridae) and one unidentified nematode. Fossilrodent middens were assigned to Lagidium viscacia (Caviomorph:Chinchillidae). The excellent preservation of parasite remains in coprolites from fossil rodent middens provided an opportunity to performe paleoparasitological inferences. The results of this papers demonstrates that fossil rodent middens offer an excellent opportunity for the recovery of parasite remains for future paleoparasitological studies in the southwest of South America.
