Öğe The antiquity of Asian chameleons-first potential Chamaeleonidae and associated squamate fauna from the Lower and Middle Miocene of Anatolia(Taylor & Francis Inc, 2022) Georgalis, Georgios L.; Cernansky, Andrej; Goktas, Fikret; Alpagut, Berna; Sarbak, Aysegul; Mayda, SerdarWe here describe fossil remains from three Lower and Middle Miocene localities of Anatolia, which we tentatively refer to chamaeleonids. The material comprises isolated tooth-bearing bones from the Early Miocene (MN 3) of Sabuncubeli (western Anatolia), the Early Miocene (MN 4) of Dededag (western Anatolia), and the Middle Miocene (MN 5) of the world-renowned hominoid locality of Pasalar (northwestern Anatolia). If our identifications are correct, these specimens would represent the only fossil record of this group from Anatolia as well as the oldest occurrences of chameleons from Asia. Moreover, the recovery of these specimens across different Lower and Middle Miocene localities, suggest that these animals were a typical element of the Anatolian herpetofaunas of the early Neogene. Differences among the specimens from the three localities point to a higher taxonomic diversity of Miocene Anatolian chamaeleonids, however, based on such limited material, intraspecific or ontogenetic variation cannot be ruled out. The oldest among these occurrences, the Sabuncubeli material, coincides chronologically with the oldest chameleons, which had been previously described from Central Europe (MN 3). As such, this supports the recently suggested biogeographic scenario, according to which chamaeleonids dispersed from Afro-Arabia to Europe during the Burdigalian, via the Gomphotherium Landbridge, through Anatolia and the Balkans. Finally, a few additional lizard and snake remains from the locality of Dededag are described, adding to the poorly known fossil herpetofaunas of Anatolia.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; Sarbak, Aysegul; 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 The westernmost Asian record of pythonids (Serpentes): the presence ofPythonin a Miocene hominoid locality of Anatolia(Taylor & Francis Inc, 2020) Georgalis, Georgios L.; Mayda, Serdar; Alpagut, Berna; Sarbak, Aysegul; Guler, Gulsah[No abstract available]
