16,000-Year-Old Mammoth Tusk Found In Seattle Is 'Rare Opportunity' To Study Ice Age Conditions In Northwest

The ice-age mammoth tusk discovered at a construction site in Seattle, Wash., is at least 16,000 years old and could be as old as 60,000 years, according to paleontologists studying the fossilized tusk. CNN reports that after scientists safely exhumed the 8-foot, 6-inch mammoth tusk on Friday, they noted that the tusk is most likely from a Columbian mammoth.
