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, 47 degrees 57'S 72 degrees 05'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 sp. (Nematoda: Trichuridae), Calodium sp., Eucoleus sp., Echinocoleus sp. and an unidentified capillariid (Nematoda: Capillariidae) and for eggs of Monoecocestus (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.
本研究旨在检查从位于佩里托莫雷诺国家公园（圣克鲁斯省，南纬 47°57'，西经 72°05'）的阿拉罗·德斯塔卡托·瓜尔帕帕克（ADG）考古遗址收集的啮齿动物粪便化石中存在的寄生虫遗骸。从 ADG 的第 7、6 和 5 层获得了 48 个粪便化石，其年代分别为 6700 +/- 70、4900 +/- 70 和 3440 +/- 70 年前。使用古寄生虫学程序对粪便样本进行了处理和检查。在 47 个粪便化石中发现了 582 个寄生虫卵。样本中含有旋毛虫属（线虫科：旋毛科）、Calodium sp.、Eucoleus sp.、Echinocoleus sp. 和一种未鉴定的毛细线虫（线虫科：毛细科）以及 Monococcestus（圆线虫科：棘头虫科）的卵。记录了各层中粪便化石和寄生虫的定量差异。在这项研究中，讨论了寄生虫的特定亲缘关系、它们的人畜共患重要性、根据先前的动物考古学知识确定的啮齿动物身份，以及全新世该地区的环境条件。
