AbstractThree localities in the Çankırı Basin—Kale Tepe 1 (KT1), Kale Tepe 2 (KT2), and Mahmutlar—yielded reliably documented rodent and lagomorph assemblages. These are in the Akkaşdağı Formation, which covers large areas in the central and southern parts of this basin in Central Anatolia. The widening of the Kirikkale-Çorum highway produced fresh outcrops that allowed for the discovery of fossiliferous levels in a well-controlled stratigraphy. The assemblages from all three localities are dominated by muroid rodents (Apodemus gorafensisRuiz Bustos et al., 1984;A. gudrunaevan de Weerd, 1976;A. dominansKretzoi, 1959;Micromyssp. indet.;Allocricetussp. indet.;Pseudomerionessp. indet.; Cricetidae gen. indet. sp. indet.;Mimomyssp. indet.) in addition to a glirid (Dryomimuscf.D. eliomyoidesKretzoi, 1959), an eomyid (Keramidomysaff.K. ermannorumDaxner-Höck and Höck, 2009), two ochotonids (Prolagus sorbiniiMasini, 1989;Ochotonomasp. indet.) and one leporid. KT1 and KT2 yielded two large species ofApodemus(A. gorafensis;A. gudrunae) that are typical for the late Miocene/early Pliocene transition in southern Europe, and they are known in Greece and Turkey in localities dated to the latest Miocene, i.e., MN 13 mammalian zone. The occurrence ofA. dominansand a rooted arvicolid similar toMimomys davakosivan de Weerd, 1979 suggests correlation of Mahmutlar to the early Pliocene, or early MN 15 zone. An abundance of muroid rodents in these assemblages indicates woodlands and areas covered by grasses and shrubs, whereas early Pliocene deposits at Mahmutlar provided pollen of abundant herbaceous and shrub elements. Most rodents and lagomorphs from Kale Tepe and Mahmutlar are known in southern European bioprovinces, whereas some elements (PseudomerionesSchaub, 1934;OchotonomaSen, 1998) indicate Asiatic affinities.
