Özet
Crocodylia indet. (Fig. 5) MATERIAL. — Turkey. Kavakdere: an osteoderm (EUNMH PV 14073). Kocayarma: 14 isolated teeth (EUNMH PV 14074– EUNMH PV 14087). Kargi 2: two teeth (EUNMH PV 14068 and EUNMH PV 14069). DESCRIPTION Osteoderm The isolated osteoderm EUNMH PV 14073 is relatively large, with a maximum length of 12 mm (Fig. 5A, B). On its external surface, a prominent longitudinal ridge runs throughout large part of its midline. Large pits of irregular size punctuate its external surface, on both sides of the ridge. Small pits are also present on the internal surface of the specimen. Teeth All teeth are conical; some of them are relatively robust, while others are more slender (Fig. 5 C-J). Their crown varies in pointness, being either pointed or apically blunt. A prominent mesiodistal serration is present in some teeth. These mesiodistal serrations separate the lingual and slightly concave surface from the labial, slightly convex one. Distinct elongated wrinkles are present in most teeth. COMMENTS Crocodylian teeth cannot afford a more precise taxonomic assignment (Georgalis et al. 2016, 2019a). The same applies for the single isolated osteoderm. On the absence of any diagnostic cranial remains, we therefore have to consider all this material as indeterminate crocodylians. Note also that crocodylian teeth from Kargi 2 have recently been mentioned by Vasilyan et al. (2019), however, they have not been figured.
