The external morphological, X-ray, and tomographic study of a frozen rodent mummy from the Upper Pleistocene Yedoma deposits on the Tirekhtyakh River (a Semyuelyakh River tributary, Abyi ulus, Republic of Sakha (Yakutia), Russia) showed its belonging to Lemmus sp. The radiocarbon age of the finding is 41 305-41 885 cal B.P. This is the first Pleistocene discovery of a frozen mummy of a genus Lemmus representative. In terms of the body and skull sizes, coat color, the lower incisor length, and the molar structure, the specimen studied is similar to the recent Lemmus sibiricus (Kerr, 1792). Comparison of the mitochondrial COB gene sequence with the DNA sequences presented in the GenBank database also testified to the maximum similarity with the Recent Siberian brown lemming.
对取自俄罗斯萨哈（雅库特）共和国阿比尤卢斯区捷列赫季亚赫河（谢苗尤利亚赫河的支流）上更新世耶德马沉积物中的一具冰冻啮齿动物木乃伊进行的外部形态学、X射线和断层扫描研究表明，它属于旅鼠属。该发现的放射性碳年代为公元前41305 - 41885年。这是首次在更新世发现旅鼠属代表性动物的冰冻木乃伊。就身体和头骨大小、毛色、下门齿长度以及臼齿结构而言，所研究的标本与现存的西伯利亚旅鼠（克尔，1792年）相似。将线粒体COB基因序列与GenBank数据库中呈现的DNA序列进行比较，也证明与现存的西伯利亚棕旅鼠相似度最高。
