A fossil assemblage of dormice (Rodentia: Gliridae) was uncovered at the (Lower?) Villafranchian site of Węże 2 in southern Poland. Based on morphometric criteria, the diagnostic M1 and m1 specimens are assignable to Glis minor and Glis sackdillingensis, two species which differ only in the dimensions of their cheek teeth. The presence of dormice at Węże 2 implies that the fossil assemblage of this site represents an at least partly wooded environment. The enamel structure in the glirids from Węże 2 is formed predominantly by radial enamel. A thin layer of lamellar enamel, occurring close to the enamel-dentine junction, may be present. Such a type of enamel structure is typical of the Myomorpha, the clade of rodents encompassing the Muroidea (the mouse-like rodents) and Gliridae.

在波兰南部 Węże 2 的（Lower？）Villafranchian 遗址发现了睡鼠（啮齿目：Gliridae）的化石组合。根据形态测量标准，诊断 M1 和 m1 标本可分配给Glis minor和Glis sackdillingensis，这两个物种仅在颊齿的尺寸上有所不同。Węże 2 的睡鼠的存在意味着该地点的化石组合至少代表了部分树木繁茂的环境。Węże 2 的 glirids 中的珐琅质结构主要由放射状珐琅质形成。可能存在靠近釉质-牙本质交界处的薄层状釉质。这种类型的牙釉质结构是 Myomorpha 的典型特征，Myomorpha 是啮齿动物的进化枝，包括 Muroidea（类似老鼠的啮齿动物）和 Gliridae。
