Results of paleoparasitological examination of rodent coprolites collected from archaeological and paleontological sites from Patagonia, Argentina, are present. Each coprolite was processed, rehydrated, homogenized, spontaneously sedimented and examined using light microscope. Coprolites and eggs were described, measured and photographed, and were compared with current faeces of Lagidium viscacia. Eggs with morphological features, attributed to an anoplocephalid cestode were found in samples collected from Cueva Huenul 1 (36°56'45″S, 69°47'32″W, Neuquén Province, Holocene) and Los Altares Profile (43º53'35″S, 68º23'21″W, Chubut Province, Late Holocene). These are the first findings of this anoplocephalid from faecal material from patagonic rodents.
本文展示了从阿根廷巴塔哥尼亚的考古和古生物学遗址收集的啮齿动物粪便化石的古寄生虫学检查结果。对每块粪便化石进行处理、复水、均质化、自然沉淀，然后用光学显微镜检查。对粪便化石和虫卵进行了描述、测量和拍照，并与目前的草原豚鼠粪便进行了比较。在从胡努尔1号洞穴（南纬36°56'45″，西经69°47'32″，内乌肯省，全新世）和洛斯阿尔塔雷斯剖面（南纬43º53'35″，西经68º23'21″，丘布特省，晚全新世）采集的样本中发现了具有裸头绦虫形态特征的虫卵。这些是首次从巴塔哥尼亚啮齿动物粪便材料中发现这种裸头绦虫。
