Section MISCELLANEOUS NEW UNIQUE MUSCLE OF THE ELBOW JOINT IN HOWLER MONKEY (ALOUATTA SENICULUS) Novikova Mellin Department of Anthropology, Biological Faculty, Lomonosov Moscow State University, Moscow, Russia In this study, we are investigating the group of muscles located on the preaxial aspect of a forearm in howler monkey (Alouatta seniculus). <...> All primates, including humans, usually have three muscles in this area: m. supinator, m. brachioradialis, m. extensor carpi radialis longus and m. extensor carpi radialis brevis. <...> However, some mammals do not have m. brachioradialis and have mm. extensores carpi radiales joined in one. <...> During dissection of a young specimen of the howler monkey, we discovered a supernumerary muscle. <...> On the other hand, in human surgery there are reports on the reduplication, anomalous structure and topography of the four typical preaxial muscles of the forearm occurring at high frequency (up to 50%). <...> A research of such anomalous muscles is very important for the use of their tendons in ‘hand surgery’. <...> To determine the homology of the unusual muscle that we found, we compared it with the known abnormal and extra muscles of the preaxial aspect of forearm in humans and other primates, as well as some other mammals and reptiles. <...> In this area of forearm, in some lower tetrapods there is a fi fth muscle called m. tractor radii, which is most similar in its position to the supernumerary muscle of the howler monkey, but differs from it, as well as from all the other muscles considered, by its innervation. <...> Key words: primates, forearm, extensors, anomaly Contact information: Novikova Mellin, e-mail: fartuna@mail.ru. 107 CARNIVORES FROM THE LATE MIOCENE LOCALITY OF HAYRANLI (HAYRANLI, SIVAS, TURKEY) Ozkurt Sakir Onder1 Turkey 3 , Gьleз Erksin Savas2 , Erkman Ahmet Cem3 1Department of Science Teaching, Faculty of Education, Ahi Evran University, Kırsehir, Turkey 2Department of Anthropology, Faculty of Languages, History and Geography, University of Ankara, Ankara, Department of Anthropology, Faculty of Science and Literature, Ahi Evran University, Kırsehir, Turkey The locality of Hayranlı-Sivas is one of the few known late Miocene localities in Turkey with the presence of large mammals. <...> Thus, the study of Hayranlı is very important to understand <...>
