Celebrate #FossilFriday this #StPatricksDay with the 1,500 pound Irish Elk! The Irish elk's enormous antlers, some of which reached a 13-foot spread, were used in ritualized combat between males. Adapted to live on grassy terrain, this elk became extinct some 10,000 years ago, possibly because of loss of habitat.
