Death of the Megabeasts

Nova examines a cosmic catastrophe

Monday, Feb. 22, 2010

Fifteen thousand years ago North America was like the Serengeti on steroids, with mega-creatures roaming a continent teeming with incredible wildlife. But then, in a blip of geologic time, somewhere between 15 and 35 magnificent large types of animals went extinct. Nova joins forces with prominent scientists to test a startling theory that may finally explain the “Megabeasts’ Sudden Death,” airing Tuesday, Feb. 23 at 8/7 p.m. CT on KET.

“Megabeasts’ Sudden Death” probes the daring idea that a comet broke apart in the atmosphere and devastated North America 12,900 years ago. In an exclusive report of tantalizing evidence supporting the theory, Nova brings leading climate scientist Paul Mayewski of the University of Maine to the Greenland ice sheet, where he discovers an incriminating clue: microscopic diamonds that are believed to be the result of a powerful impact of extraterrestrial origin.

And, don’t miss Nova next week, as Neil deGrasse Tyson takes a light-hearted look at the solar system’s best-loved non-planet. “The Pluto Files” airs Tuesday, March 2 at 8/7 p.m. CT on KET.
