Eggs representative of a digenean species were found in coprolites belonged to an endemic deer from Patagonia. Samples were collected from the archaeological site named "Cueva Parque Diana". This site is a cave located at the Lanín National Park, Neuquén Province, Argentina. The coprolites were dated from 2370±70 to 580±60 years B.P. The eggs were ellipsoidal, operculated, yellowish and thin-shelled. Measurements (n=65) ranged from 120.0 to 142.5 (133.2±6.53) μm long and 62.5 to 87.5 (72.6±6.15) μm wide. Eggs were well-preserved and were identified as belonged to Class Trematoda, Subclass Digenea, similar to those of Fasciola hepatica or with another species not identified at present from Patagonia. This is the first report of digenean eggs from ancient deer worldwide. The present study confirms the presence of representatives of digenean species in endemic deer from Patagonia in ancient times and the presence of a trematode disease prior to the arrival of European cattle.
在属于巴塔哥尼亚一种特有鹿类的粪化石中发现了一种复殖吸虫的卵。样本采集自名为“库埃瓦·帕克·戴安娜”的考古遗址。该遗址是一个位于阿根廷内乌肯省拉宁国家公园的洞穴。这些粪化石的年代为公元前2370±70年至580±60年。卵呈椭圆形,有卵盖,淡黄色,壳薄。测量值(n = 65)为长120.0至142.5(133.2±6.53)μm,宽62.5至87.5(72.6±6.15)μm。卵保存完好,被鉴定为属于吸虫纲复殖亚纲,与肝片吸虫的卵相似,或与目前尚未从巴塔哥尼亚鉴定出的另一种物种的卵相似。这是全球范围内首次关于古代鹿类复殖吸虫卵的报告。本研究证实了古代巴塔哥尼亚特有鹿类中存在复殖吸虫物种的代表,以及在欧洲牛到来之前就存在吸虫病。
