“…However, only additional and more complete specimens from the area can shed light on the chameleon evolution and the taxonomic diversity of this clade in Anatolia during the Miocene. As for the remaining squamates described herein, their fragmentary nature does not afford much biogeographic information but nevertheless they substantially add to the so far poor Miocene fossil record of squamates from Anatolia (see C ̌ernǎnský, Vasilyan, et al, 2017;Georgalis et al, 2018;Syromyatnikova et al, 2019Syromyatnikova et al, , 2022Vasilyan et al, 2019;Georgalis, Mayda, et al, 2020).…”

We 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 Dededağ(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 Dededağare described, adding to the poorly known fossil herpetofaunas of Anatolia.

“…The application of µCT technology provides researchers with an outstanding view of the development of the pharyngeal jaw and teeth, the mechanism of teeth replacement, as well as morphometric data for comparisons between species and within each species from different body sizes (Bruneel et al, 2015, Pasco-Viel et al, 2010. Therefore, when applying µCT technology for taxonomic identification of archaeological and palaeontological remains, it can be performed in a reliable way, regardless of specimen size (Vasilyan et al, 2019).…”

“…Description and remarks —Both osteoderms are fragmentarily preserved. Their dorsal surface possesses a characteristic ornamentation (e.g., Chroust et al, 2021; Vasilyan et al, 2019) made of a network of rounded deep pits (NMNHU-P 52-165) or of rounded deep pits and radially projecting depressions (NMNHU-P 52-161). The available material cannot be closer identified because of its poor state of preservation.…”

The Zaysan Basin in Central Asia has a long geological history, and it has therefore seen major climatic and evolutionary transformations. The Miocene fossil record of this locality is remarkably rich representing all groups of vertebrates. A revision of fish remains has been carried out and new records of fishes, reptiles, and mammals recovered from Miocene deposits of the Zaysan Basin have been described. The study of fossils has revealed the existence of a quite diverse vertebrate assemblage in the basin during the Miocene. Representatives of the Percidae and Amiinae, and the species †Leobergia zaissanica predominated among fishes, whereas reptiles were supposedly represented in the assemblage by pan-trionychid turtles and crocodiles. No amphibians have been revealed, while the only mammalian taxa in the studied sample is a fossorial rodent of the genus †Tachyoryctoides. In contrast to previous views regarding the Middle Miocene age of the Zaysan Formation, the analysis of fish and mammal remains recovered from this locality strongly suggests an Early Miocene age. Findings of bowfin remains in the Zaysan Basin confirm that this group had existed outside of North America beyond the Paleogene/Neogene transition, and, at the same time, these specimens are the last known occurrences of the taxa Amiidae, Amiiformes, and Halecomorphi outside of North America. Data also indicate the existence of a lacustrine ecosystem in the Zaysan Basin during the Miocene with a taxonomically rich vertebrate assemblage and diverse trophic relations being an important center of biodiversity in the Miocene of Central Asia.
