Les mollusques du site paléolithique de Mezhyrich (Ukraine, Pléistocène supérieur)

This paper presents the results of the analysis of molluscan assemblages from two layers of the Paleolithic site of Mezhyrich (Ukraine, Upper Pleistocene). Fourteen terrestrial mollusc taxa were identified. They mostly belong to seven terrestrial genus (Succinella, Pupilla, Vertigo, Truncatellina, Columella, Vallonia, Chondrula) and four aquatic ones (Unio, Cyclas, Planorbis, Anisus). In addition, we note the presence of three Neogene marine taxa and one foraminifera taxa, all redeposited. A short systematic description of the terrestrial mollusc taxa is presented with illustrations. The molluscan fauna sampled in units below the archaeological layers called toptalishche, is typical from stadial loessic deposits, whereas that associated with the toptalishche is characteristic of drier and milder local conditions.
