? Eopelobates sp. (Fig. 3) MATERIAL. — Turkey. Kocayarma: a fragment of a left maxilla (EUNMH PV 14065). DESCRIPTION AND COMMENTS The fragment of a left maxilla (EUNMH PV 14065) is small, with a maximum preserved length of 4.5 mm (Fig. 3). Its external surface is covered by an array of prominent, dense pits and ridges. This prominent sculpturing pattern of the isolated fragmentary maxilla EUNMH PV 14065,consisting of dense pit and ridges, that is integral part of the bone and not a secondary exostosis, is reminiscent of pelobatids (see figures in Roček et al. 2014; Blain et al. 2016). The pits are rather deep and anteroposteriorly elongated. Among pelobatids, this sculpturing pattern with dense pits and ridges is more consistent with Eopelobates, a genus that has a broad distribution in the late Cretaceous and Paleogene of North America, the Paleogene and Neogene of Europe, and the Paleogene of Central Asia (Roček et al. 2014), while it has been recently described also from the earliest Miocene of Anatolia (Syromyatnikova et al. 2019a). Such sculpturing pattern is also present in Oligo-Miocene remains attributable to Pelobates Wagler, 1830 (Roček et al. 2014), however, on the other hand, more recent remains and extant forms of the latter genus are characterized by a rather pustular pattern with numerous isolated tubercles (Venczel 2004; Roček et al. 2014).
