EDIT
World's Greatest Mysteries Dinosaur Extinction: Fire Or Flood?
AIRED:
Controversy. Conspiracy. Confusion. History is fraught with events -- from local to global -- that have never been satisfactorily explained. What caused the dinosaurs to perish? How were the Egyptian Pyramids built? What happened to the great Inca civilization? Was John Wilkes Booth part of a large, sinister plot? Was George Armstrong Custer sacrificed to save the Grant Administration? Is there anything happening in Roswell, New Mexico, that should be shared with American citizens? Who shot John F. Kennedy? These and dozens of other international mysteries are investigated, explored, unraveled and reported. Dinosaur Extinction: Fire Or Flood? Dinosaurs--and many other groups of animals--suddenly became extinct approximately 65 million years ago. Known as the --Cretaceous-Tertiary Extinction Event, the cause of this mass extinction has been extensively studied since the 1970s. Although no definitive explanation has been reached, it is known that the climate of earth before the event was much warmer and milder than it is now. This television program considers what may have happened to change the earth's weather. Was the event triggered by the impact of a giant asteroid? Some scientists suggest that an asteroid hit in the vicinity of the Yucatán Peninsula at that time, creating a 110 mile wide crater. Alternative theories include other global disturbances like momentous volcanic activity or a worldwide flood. Scientists have long believed that the layers of sediment--known as the --Geologic Column?--that have been used to determine the age of the world were formed gradually, revealing a slow change in the earth. The biblical account of Noah's flood would indicate a rapid and sudden change. Which is correct? Did man coexist with the dinosaurs? Learn the newest theory of the age of the earth.moreless
