RE-THINKING EXTINCTION... THE "DISCOVERY FILES": NEW ADVANCES IN SCIENCE AND ENGINEERING, FROM THE NATIONAL SCIENCE FOUNDATION. TALK ABOUT HAVING A BAD WEEK: IT SEEMS THAT THE DINOSAURS HAD A BAD 500-THOUSAND YEARS! GROWING EVIDENCE SHOWS THAT IT WAS NOT A SINGLE METEOR IMPACT THAT DID IN THE DINOSAURS--BUT MORE LIKE A LONG PERIOD OF MULTIPLE METEOR HITS, MASSIVE VOLCANIC ACTIVITY, SEVERE CLIMATE CHANGE, AND A FINAL CATASTROPHIC, YET UNIDENTIFIED, METEOR IMPACT SOMEWHERE ON EARTH. IN FACT, RESEARCHERS FROM PRINCETON--IN COLLABORATION WITH SWISS AND GERMAN UNIVERSITIES--HAVE FOUND CLUES THAT INDICATE THAT THE NOW-FAMOUS METEOR IMPACT AT CHICXULUB--SUPPOSEDLY, THE "BIG ONE"--ACTUALLY OCCURRED SOME 300-THOUSAND YEARS BEFORE THE DINOSAURS' DEMISE. THEY SAY THAT THE MORE-LIKELY SCENARIO IS THAT METEORS, VOLCANOES, CLIMATE CHANGE, AND A FINAL MEGA-METEOR SEALED THEIR FATE. THEY'RE STILL LOOKING FOR THE SMOKING GUN--ER, CRATER--FROM THE IMPACT THAT HAD A REAL IMPACT ON THE DINOSAURS. THE "DISCOVERY FILES" COVERS PROJECTS FUNDED BY THE GOVERNMENT'S NATIONAL SCIENCE FOUNDATION: FEDERALLY SPONSORED RESEARCH BROUGHT TO YOU BY YOU! LEARN MORE AT "N-S-F"-DOT-GOV--OR ON THEIR PODCAST.
