Date:2008/05/16 - 2008/05/25

I have visited Prof. Nikolai P. KalmykovDuring of the Southern Sciencific Centre (SSC), Russian Academy of Science (RAS), in Rostov-na-Donu, Russia from May 16th through May 25th, 2008. Many mammalian fossils, including colobine monkey, are housed at the laboratory of Prof. Kalmykov of SSC, which have been collected from the middle Pliocene sediments of Udunga, Transbaikalia, southern Sibelia. During my stay in Rostov I observed the fossil specimens of these Udunga mammals including primates. The Udunga fauna, which includes eight mammalian orders (Lagomorpha, Rodentia, Primates, Carnivora, Artiodactyla, Perissodactyla, Proboscidea, Hyracoidea), is expected to play an important role for the analysis of the evolutionary history of the Eurasian primates. This time, I have examined mainly primates and artiodactyls specimens, and measured some of these specimens, using caliper and took some mould of the specimens for making the replicas for detailed analysis.
