Measuring over 10 feet in height. Entombment for thousands of years in the Siberian permafrost has produced its distinctive brown patina. An extinct ancestor to today’s elephant that ranged throughout Eurasia and North America during the Pleistocene, Woolly Mammoths were a very successful species. Using their long, curved tusks to sift the snow to forage for vegetation, and possessing long, thick coats and ample body fat, Woolly Mammoths were well adapted to the frozen wastelands of the last Ice Age. The males may have also used their tusks in intra-species combat or competition for females. Scientists speculate that human hunting may have been partly responsible for their extinction.
