The mammal bearing locality Blanquatère 1 delivers the highest diversified glirid fauna of middle Miocene age (near MN 4/MN 5 boundary) discovered up to now in southern Europe: nine genera and 16 species. Three species are new: Prodryomys remmerti n. sp., a large-sized species with only a few accessory crests, Glirudinus intermedius n. sp., intermediate in size and shape between G. minutus and G. modestus, and Glirudinus magnus n. sp., the largest species of the genus presently known; the two former and the genus Muscardinus are possible migrants. Remarks are made about the phylogeny of Glirudinus and Prodyromys, and the stratigraphic distribution of Vasseuromys species must be extended. The overall fauna of glirids suggests a significant forest cover.
