Fossil (paleotheriology). IX Congress of the Russian Theriological Society “Theriofauna of Russia and adjacent areas”, Moscow, 2011

In Russia there is no special professional society mammalian faunas at – Holocene transition devoted to studies of mammals or vertebrate (from ca. 24 to ca. 8 ka). This study is based on approx- paleontology. This is why special sessions on paleothe- imately 5800 radiocarbon dated mammalian faunas de- riology in the structure of Russian theriological con- rived from the PALEOFAUNA database, which is be- gresses are among the few nation-wide conferences ing developed by the authors. devoted to fossil mammals.
