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.

The tectonic evolution of Lake Eğirdir, West Turkey Lake Eğirdir is one of the most important fresh-water lakes of Turkey. It has a tectonics-related origin. The area formed under a roughly N-S compressional tectonic regime during the Middle Miocene. The stresses caused slip faults west and east of Isparta Angle, and the lake formed at the junction of these faults. The area subsided between normal faults, thus creating the topographic condition required for a lake. The lacustrine sediments have fundamentally different lithologies. After the Late Miocene, central Anatolia started to move westwards, but western Anatolia moved in a SW direction along the South-western Anatolian Fault, which we suggest to have a left lateral slip, which caused that the Hoyran Basin moved t7 km towards the SW and rotated 40° counterclockwise relative to Lake Eğirdir.

Abstract. We describe here five new bovid crania from the Çorakyerler fossil site (Tüglu Formation, Çankırı Basin, north-central Anatolia, Turkey), the fauna of which is dated by magneto- and biostratigraphy to the late Miocene, around the Vallesian–Turolian boundary. The material is assigned to a new bovid taxon of medium-to-large size, Gangraia anatolica gen. and sp. nov., characterized by horn cores that are long, keelless, compressed, obliquely inserted on the frontals, transversally ridged, moderately diverging from each other, slightly twisted homonymously, and sigmoidally curved in lateral view with long, fairly straight tips. The horn core features, along with the presence of a single large sinus occupying the pedicle and the base of the horn core, a strong cranial flexion, a short braincase, the presence of a distinct dorsal parietal boss, wide-apart temporal crests, and a widened anteriorly basioccipital, indicate a mixture of caprine-like and alcelaphine-like features that relate Gangraia anatolica gen. and sp. nov. to the Alcelaphini–Caprini–Hippotragini clade.
