• Zoboli et al. 2019: “Formazione lacustre” Auct. = Perfugas Fm. (Burdigalian, MN3; Van der Made, 2008; Zoboli and Pillola, 2017b). The vertebrate site is represented by a small exposure of lacustrine clay in a road cut near the village of Oschiri (De Bruijn and Rümke, 1974). The age of the mammal assemblage of Oschiri has been discussed by several authors (e.g. De Bruijn and Rümke, 1974; Azzaroli and Guazzone, 1979; Azzaroli, 1983; Van der Made, 2008). The micromammals are quite diverse, with nine taxa including seven endemic species (De Bruijn and Rümke, 1974). The advanced endemism of Ctenodactylidae and the presence of Gliridae, Talpidae and Soricidae are very similar to the mainland taxa, and suggest different phases of colonization of the Corsica Sardinia Massif (Ferrandini et al., 2000; Mennecart et al., 2017, 2019). The Oligo-Miocene palaeogeographical context of the western Mediterranean indicates that the latest additions to the insular association arrived in Sardinia during the European Land Mammal Unit MN3, which is coincident with the early Burdigalian marine regression, around 20 Ma ago (Van der Made, 2008; Zoboli and Pillola, 2017b).
