FIGURE 2. Environs of Solna Jama Cave entrance ( 1), showing the fissured crystalline limestones, in which the cave developed. The “Wolverine Niche” ( 2) and the corrosion, phreatic features of the cave passage (3). The “Wolverine Niche” is the place in the cave, where partially preserved skeleton of particularly large Gulo gulo was found (Photo by K. Stefaniak).

FIGURE 13. Scatter diagram showing the ratio of lower carnassial (m1) length (Lm1) and breadth (B m1) in late Pleistocene and Recent Mustela nivalis from Poland. The Solna Jama Cave specimen displays a moderately large size, with the length of m1 less than 4 mm, typical of the late Pleistocene and postglacial period.
