VICTORIA, CANADA—Fossilized footprints discovered below the current shoreline of an island in British Columbia may be the oldest in North America. The prints, thought to have been made by a man, a woman, and a child some 13,000 years ago, were discovered on Calvert Island last year near the remains of an ancient campfire. “We figure that at some point people were hanging out around this fire. They left their footprints in the grey clay and then they were subsequently filled by this black sand, which essentially preserved the footprints,” archaeologist Duncan McLaren of the University of Victoria told the National Post.
