In 1978, two men were exploring a dry creek bed in Waco, Texas, looking for arrowheads, when they came across a bone sticking out of the ground. They took the bone to Baylor University here in Waco, where it was identified as a leg bone belonging to a Mammoth.
A mammoth is any species of the extinct pre-historic elephant, equipped with long, curved tusks and, in the northern species, a covering of long hair. They lived from 5 million to 2 million years ago in Africa, Europe, Asia, and North America.
A team from the University began excavating the sight and found 23 mammoths, the largest nursery heard (adults and juveniles) in the United States. Some were removed for study. A dig shelter was constructed over the remaining. That structure ultimately became a permanent building opened to the public in 2009.
