Decay of uranium to lead within tiny crystals enabled scientists to precisely pinpoint dates for certain events. They determined this event occurred 119.5 million years ago -- coincident with evidence for massive volcanic eruptions -- and lasted for 1.1 million years. Study results help scientists better understand links between atmospheric CO2 levels, climate changes and conditions in the oceans.Antarctica's irregular heartbeat shows signs of rapid melting
