Morphological study of new cranial and dental material of the bear from Sesklo, Magnesia

The fossiliferous site of Sesklo, Magnesia has been dated to the Lower Pleistocene (~2,4 Ma), and it is internationally known for the fossils of vertebrates found there. The purpose of this thesis is the morphological study of new craniodental material of the Sesklo bear and its comparison to samples of the genus Ursus from various European localities. The material comprises an almost complete cranium, a left upper canine and a right lower first molar. To facilitate the morphological study, a 3D model of the cranium was created using the method of photogrammetry. The cranium is distorted and it lacks some parts of the neurocranium, as well as the zygomatic arches. It retains part (P4–M2) of the dentition. Based on the dental wear, the individual was at the transition towards old age. The m1 is less worn and it is associated with a different, middle aged, individual. The body mass of the individual associated with the cranium was calculated at 153–162 kg, while the m1 belongs to an individual that weighed 86 kg. The sex of the individual associated with the cranium was determined as female. All the material was ascribed to the species Ursus etruscus. The comparison of the material with samples of the genus Ursus from other European localities, showed that the bear of Sesklo presents plesiomorphic features and is morphologi-cally closer to Ursus etruscus from Saint-Vallier.
