Abstract

The aim of this study was to examine the parasite remains present in rodent coprolites collected from the archaeological site Alero Destacamento Guardaparque (ADG) located in the Perito Moreno National Park (Santa Cruz Province, 47º57'S 72º05'W). Forty-eight coprolites were obtained from the layers 7, 6 and 5 of ADG, dated at 6,700 ± 70, 4,900 ± 70 and 3,440 ± 70 years BP, respectively. The faecal samples were processed and examined using paleoparasitological procedures. A total of 582 eggs of parasites were found in 47 coprolites. Samples were positive for eggs of Trichuris check for this species in other resources sp. (Nematoda: Trichuridae), Calodium check for this species in other resources sp., Eucoleus check for this species in other resources sp., Echinocoleus check for this species in other resources sp. and an unidentified capillariid (Nematoda: Capillariidae) and for eggs of Monoecocestus check for this species in other resources (Cestoda: Anoplocephalidae). Quantitative differences among layer for both coprolites and parasites were recorded. In this study, the specific filiations of parasites, their zoonotic importance, the rodent identity, on the basis of previous zooarchaeological knowledge, and the environmental conditions during the Holocene in the area are discussed.
