Breef content: |
The scientist from the Institute of Plants and Animals Ecology, Russian Academy of Sciences (Ural Branch), has made a description of the giant dear remains, found in the Ural, and has determined their age. Giant deer (Megaloceros giganteus) originated as a species in the preglacial epoch, lived through the glaciation period and died out about 8-9 thousand years ago after the climate had become warmer. The remains will help to investigate how the giant dear lived and why this species disappeared. The research has been carried out with the help of the Russian Foundation for Basic Research grants 02-04-49431 and 'The evolution of the mammalian fauna and flora in Western, Central and Eastern Europe during the Pleistocene-Holocene transition (25-10 kyr B.R.)'.
