Öğe A new ape from Türkiye and the radiation of late Miocene hominines(NATURE PORTFOLIO, 2023) Sevim Erol, Ayla; Begun, David R.; Yavuz, Alper; Tarhan, Erhan; Sönmez Sözer, Çilem; Mayda, Serdar; Ostende, Lars W. van den Hoek; Martin, Robert M. G; Alçiçek, Mehmet CihatFossil apes from the eastern Mediterranean are central to the debate on African ape and human (hominine) origins. Current research places them either as hominines, as hominins (humans and our fossil relatives) or as stem hominids, no more closely related to hominines than to pongines (orangutans and their fossil relatives). Here we show, based on our analysis of a newly identified genus, Anadoluvius, from the 8.7 Ma site of Corakyerler in central Anatolia, that Mediterranean fossil apes are diverse, and are part of the first known radiation of early members of the hominines. The members of this radiation are currently only identified in Europe and Anatolia; generally accepted hominins are only found in Africa from the late Miocene until the Pleistocene. Hominines may have originated in Eurasia during the late Miocene, or they may have dispersed into Eurasia from an unknown African ancestor. The diversity of hominines in Eurasia suggests an in situ origin but does not exclude a dispersal hypothesis.Öğe Hyracoidea from the Middle Miocene hominoid locality of Pasalar (NW Turkey)(Scientific Technical Research Council Turkey-Tubitak, 2020) Pickford, Martin; Mayda, Serdar; Alpagut, Berna; Demirel, Fatma Arzu; Şarbak, Ayşegül; Kaya, Tumel TanjuPreviously available samples of Hyracoidea from Pasalar (MN 6, Middle Miocene), Turkey, have indicated the presence of Pliohyracidae at the site, but the material was too scanty for confident identification. The single upper molar, an upper molar ectoloph fragment and an ascending ramal fragment were too uninformative for determining the taxonomic identity of the fossils, although several names have been proposed in the literature. Additional fossils collected from Pasalar include upper and lower premolars, which help to tie down the affinities of this hyracoid. They are attributed to the genus Prohyrax, but were not named specifically, even though they are somewhat larger than the largest previously described species, Prohyrax hendeyi, from basal Middle Miocene deposits in Namibia. The presence of cingulids on the lower cheek teeth and the strong parastyle in the upper premolars from Pasalar represent important similarities to the other species of Prohyrax, to the exclusion of other genera of Pliohyracidae.Öğe Karaburun Yarımadası’nın Geç Miyosen Stratigrafisi, Yeni Memeli Bulguları ve Bölgesel Korelasyon, Batı Anadolu(TMMOB JEOLOJI MUHENDISLERI ODASI, 2023) Göktaş, Fikret; Kaya, Tümel Tanju; Tarhan, Erhan; Mayda, SerdarÖz: Foça Çöküntüsü’nün batı kenarındaki Mordoğan alt havzasında tanımlanan Eşendere grubu, alüviyal Saip, palustrin Boyabağ ve gölsel Çukurcak kireçtaşı formasyonlarından oluşmaktadır. Eşendere grubu, Orta Miyosen yaşlı Hisarcık formasyonunun gölsel çökelleri üzerinde uyumsuzlukla yer alır. Alüvyon yelpazesi çökellerinden oluşan Saip formasyonu, Geç Miyosen tortullaşmasının başlangıcını yansıtır. Palustrin çamur düzlüğü istifiyle temsil edilen ve ilk kez bu çalışmada tanımlanan Boyabağ formasyonu, Saip formasyonu ile gölsel Çukurcak kireçtaşı arasında yer alır. Gölsel Çukurcak kireçtaşı, Eşendere grubunun son birimidir. Boyabağ formasyonunun çamurtaşı egemen istifi içinde bulunan Hipparion aff. giganteum ve Hippopotamodon major kıyı Ege Bölgesi'nde MN10 biyozonuna işaret eden ilk bulgulardır. Bu büyük memeli bulgularına dayanılarak, Foça Çöküntüsü’ndeki Geç Miyosen tortullaşmasının ~10 milyon yıl önce başladığı ileri sürülebilirÖğe Qurliqnoria (Bovidae, Mammalia) from the Upper Miocene of Corakyerler (Central Anatolia, Turkey) and its biogeographic implications(Elsevier, 2020) Kostopoulos, Dimitris S.; Sevim Erol, Ayla; Mayda, Serdar; Yavuz, Alper Yener; Tarhan, ErhanNew bovid material from the Upper Miocene site of corakyerler (Canlun basin, Anatolia, Turkey) is described and compared here. The described taxon is identified as a representative of the stem caprine genus Qurlignoria, previously known from the pen-Tibetan area exclusively. The stronger horn-core divergence, weaker anterior keel, smoother horn-core surface, stronger lateral horn-core curvature, stronger and thicker interfrontal suture, less flexed and less pneumatized frontals, and smaller supraorbital foramina differentiate the corakyerler Qurlignoria from the type and only known species of the genus, Q. cheni from China, and demand the erection of a new species, Qurlignoria chorakensis n. sp. A review of other late Miocene bovid records allows the recognition of Qurlignoria in Sinap Tepe (Turkey) and Platania (Greece), suggesting a westward propagation of the genus during the Vallesian.

Being thermophilous reptiles, they are distributed in tropical and sub-tropical areas in sub-Saharan Africa, southern and southeastern Asia, Philippines, Indonesia, New Guinea, and Australia (Schleip and O’Shea, 2010; Wallach et al., 2014; Head, 2015).
