title: Early Middle Pleistocene Ellobius (Rodentia, Cricetidae, Arvicolinae) from Armenia
abstract: Early Pliocene) radiation of Arvicolinae (Abramson et al., 2009a, b). Therefore, most specific features of mole voles developed due to a strong burrowing specialization (incisor digging, molar enamel thickening and partial reduction of molars) so that Early Pleistocene forms still show much more arvicoline-looking molars with some mimomyoid characters (e.g. Mimomys-ridge and relics of enamel islets). As with many rapidly evolving arvicoline phylums, molar evolution in mole voles shows a progress
