Enormous Ice Age bison skull found in Colorado

The skull of an Ice Age bison twice the size of modern bison is the latest fossil discovery coming out of Snowmass Village.

Scientists uncovered the 250-pound bison skull Saturday. The Denver Museum of Nature & Science, which is overseeing the excavation, says that when both horns were repositioned with the skull, the span of the horns was more than 6 feet.

Earlier bison specimens found at the fossil dig were smaller. Scientists have also found a Columbian mammoth, American mastodon and an Ice Age deer. The bones were first discovered last month by a construction crew.
