Core samples pulled from 2 miles beneath the ocean floor are turning up fossils of shallow water creatures. How did life forms that thrived under just 100 feet of seawater end up buried thousands of feet below the surface? One clue: the limestone around them may have formed above sea level. We're talking about a violent, planet-altering shift — fast, not slow. The radiocarbon dates? 12,000 years ago… give or take 900. What happened at the end of the last Ice Age? | The Randall Carlson
