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 Anadolu: “Ape” Evriminde Bir Kesişim Noktası, Prof. Dr. Ayhan Ersoy’un Anısına bir Sunum (Konuşmacı: Prof. Dr. David R.

In Anatolian archaeology, these animals are present in assemblages from the Early Neolithic to the Iron Age. Furthermore, there is evidence that leopards still live-in modern-day Anatolia. Although Panthera remains are present at different archaeological sites spanning multiple periods in Anatolia, an in-depth study of these bones has yet to be completed. In this study, we present the case of a distal humerus of from Neolithic period layers at Yes¸ilova Hoyük, ¨ and three mandible fragments from the Bronze Age layers at Yassıtepe Hoyük. ¨ Our detailed morphological and metric analysis indicates that the humerus can be attributed to a lion (Panthera leo) and the mandible fragments to two male individuals of the leopard species (Panthera pardus). In addition to presenting new data on the genus Panthera in ancient Anatolia, we also aim to offer a new perspective to zooarchaeology studies using detailed morphological and metric data of faunal elements in the archaeological record.Öğe First report of “Mammut” (Mammalia, Proboscidea) from the Upper Miocene of Turkey(TAYLOR & FRANCIS INC, 2023) Konidaris, George E.; Aytek, Ahmet İhsan; Yavuz, Alper Yener; Tarhan, Erhan; Alçiçek, Mehmet CihatMammutidae comprise a proboscidean family that originated in Africa during the late Oligocene, dispersedacross the Holarctic during the Miocene, and survived in North America until the end of the Pleistocene. Despite their longevolutionary history and wide geographic distribution mammutids are particularly scarce in the Miocene of Eurasia. Here, wepresent a new mammutid specimen (an upper deciduous premolar) from the Upper Miocene locality of Sazak insouthwestern Turkey. Morphological and metric traits of the tooth, in particular the well-expressed zygodonty, are distinctfrom the more basalZygolophodonand permit its assignment to the more derived“Mammut.”Due to the absence ofmore diagnostic specimens, a specific attribution is not possible; however, considering the Turolian age of the associatedfauna an attribution to the Late Miocene representative of the genus,“Mammut”obliquelophus, is possible. Turolianmammutids are rare in the fossil record and therefore our knowledge remains only fragmentary. Despite the existence ofa single specimen, the presence of this genus in Sazak corresponds to itsfirst report in the Upper Miocene of Turkey, aswell as thefirst one in western Asia. The presence of“Mammut”in the Upper Miocene of China was recently confirmed,and therefore the record of“Mammut”at Sazak, i.e., at the western margin of Asia, not only adds to the scanty record ofthe genus in the Upper Miocene of Eurasia but also provides another line of evidence of the paleozoogeographic linkenabling Europe–East Asia proboscidean interchanges during the Late Miocene.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.
