An increase in bio- important component of the Eurasian mammal diversity occurs later, during the Mindel (Elster), fauna from the end of Pliocene to the beginning indicated by the appearance of H. bonali and of Holocene. The critical revision and study of the re-immigration of O. a. antiqua. During this members of the Ovibovini and Caprini tribes from turnover, the genera are affected by an important about 200 sites, provides new insights concern- evolutionary transformation connected to global ing their immigration into Western Europe, their cooling and a change in the physical environ- origins and their evolution.
