At this lively Archaeology Café meeting, Dr. West discussed the provocative, internationally-debated theory that an enormous space object—probably a fragmented comet—exploded over the northern hemisphere 12,900 years ago. Allen is one of 26 scientists from 18 institutions who have teamed up to bring together multiple lines of evidence that may reveal this cataclysmic event. The scientists propose that the impact produced massive detonations with more force than the world’s entire nuclear arsenal. In the aftermath, North America and Western Europe were dusted with nanodiamonds, magnetic spherules, iridium, black carbon, and fullerenes filled with helium-3. Millions of animals perished—which, the team argues, ultimately led to catastrophic extinctions, a decline in human populations, and a major reorganization of the Clovis culture.
