Abstract

The article presents the findings of the paleoparasitological analysis of coprolites from the cave bear (Ursus kanivetz Vereshchagin, 1973). The material for research was obtained during excavations in the Ignatievskaya Cave (Southern Urals, Russia; 54°53′ N 57°46′ E). The deposits with coprolites date back to the middle of the Late Pleistocene (90 000–30 000 years ago). On the basis of the paleoparasitological analysis, eggs of the nematode characteristic of representatives of Ursidae, namely, Baylisascaris transfuga Rudolphi, 1819, have been established to be present in the coprolites. The eggs are well preserved and have not lost their morphological features. The large cave bear was infested by the nematode B. transfuga. This is the first find of the nematode B. transfuga in Pleistocene-aged sediments and the first find of parasites in coprolites of the cave bear.

摘要

这篇文章介绍了洞熊粪化石的古寄生虫学分析结果（Ursus kanivetz Vereshchagin，1973 年）。研究材料是在 Ignatievskaya 洞穴（俄罗斯南乌拉尔；54°53′ N 57°46′ E）的挖掘过程中获得的。粪化石的沉积可追溯到晚更新世中期（90 000-30 000 年前）。根据古寄生虫学分析，熊科代表线虫的卵，即Baylisascaris transfuga Rudolphi，1819，已确定存在于粪化石中。鸡蛋保存完好，并没有失去其形态特征。大洞熊被线虫B. transfuga 侵染. 这是在更新世沉积物中首次发现B. transfuga线虫，也是在洞熊粪化石中首次发现寄生虫。
