Abstract

Fossil remains of a collared lemming (Dicrostonyx) are described for the first time from the Late Pleistocene site of Perspektivnaya Cave (Primorsky krai). Radiocarbon dating places the finds within the MIS 2 period. Morphotype analysis of the first upper molars (M1 and M2) identified the population as Dicrostonyx torquatus. These data refine our understanding of the species’ range and chronology, indicating a more southerly distribution and an earlier presence of D. torquatus in the Late Pleistocene than previously recognized.
