Une espèce géante de MuscardinusKaup, 1829(Gliridae,Rodentia, Mammalia) dans le gisement karstique de Cala Es Pou (Miocène supérieur de Minorque,Baléares)

In this paper, Muscardinus cyclopeus nov. sp., from the locality of Cala Es Pou, in Menorca (Balearic Islands)), is described. M. cyclopeus is close to M. viretiHugueney & Mein, but shows a greater size. This species belongs to a new phase of insularity in the Balearic Islands, different from the classical Myotragus-Hypnomys-Nesiotites faunas. This phase may be due to variations in the sea level within the Messinian. Other elements belonging to this phase are: Geochelone gymnesicaBate, cf. Alilepus nov. sp. and Rhinolophus cf. grivensis (Deperet).
