Received: 2 November 2011. Accepted: 12 March 2012. KRAJCARZ M. T. 2012. Small fossil wolverine Gulo from Middle Pleistocene of Poland. Acta zool. cracov., 55(1): 79-87. Abstract. Fossil wolverine remains were excavated in Deszczowa Cave (southern Poland). The oldest specimens were found in layers I and III, related to Saalian Glaciation (OIS 6). These are: a skull fragment with upper carnassial; another skull fragment with upper incisor; and a loose upper canine. Themeasurements of the upper carnassial (buccal length = 19.5 mm, width = 11.8 mm) indicate a small sizedGulo. It may be concluded that a small form of wolverine, typical for warm periods according to Bergmann’s rule and known from late Middle Pleistocene sites of Europe and North America, was also present in Poland before the Last Glaciation. It cannot be excluded that specimens from Deszczowa Cave represent the G. schlosseri species or an intermediate form between G. schlosseri and G. gulo.
