HUGE Development In Dinosaur Extinction Theory

HUFFINGTONPOST.COM - The theory of which asteroid was responsible for killing the dinosaurs 65 million years ago has been shattered to pieces -- literally.

New data from NASA's WISE (Wide-field Infrared Survey Explorer) satellite suggests that an asteroid from the Baptistina family was actually not -- as previously thought -- responsible for the mass extinction, NASA reported on Monday.

"As a result of the WISE science team's investigation, the demise of the dinosaurs remains in the cold case files," Lindley Johnson, program executive for the Near Earth Object (NEO) Observation Program at NASA, said in a statement.

The Baptistina theory was originally published in the journal Nature in 2007.

From NASA:

According to that theory, Baptistina crashed into another asteroid in the main belt between Mars and Jupiter about 160 million years ago. The collision sent shattered pieces as big as mountains flying. One of those pieces was believed to have impacted Earth, causing the dinosaurs' extinction. >>>CLICK HERE TO READ MORE
