The enamel characteristics of fossil and modern first lower molars of the European water vole (Arvicola amphibius, Arvicolinae, Rodentia) of the Perm Pre-Urals.

This article presents data on the enamel characteristics (thickness, enamel differentiation coefficient (SDQ)) of the first lower molars of the European water vole (based on the conditional groups "juvenile" and "adult") from fossil and modern samples from the Perm Pre-Urals (Russia). Among the "adult" group teeth, samples from the Eemian (Mikulino) interglacial deposits had the highest mean SDQ values (91.5–94.8), while samples from the end of the Bryansk Interstadial, the Late Glacial, the Early Holocene deposits had the lowest (76.3–84.9).
