What Really Killed the Dinosaurs?
Several extinction theories are being batted around right now by Paleontologists.
The one that most are now gathering under the banner of the Impact Event
Theory. Impact Theory involves a large comet or asteroid striking the earth
around the K-T boundary. (Aprox. 65 million years ago) <
Luis
W. Alvarez > along with his son Walter of the University
of California at Berkeley first proposed the possibility in 1980. This
theory was part of a larger theory that showed that mass extinction happens
at regular intervals.< The
search for Nemesis >.
The second theory by Bob Bakker
of the University of Colorado, holds that the Dinosaurs died from disease
and pestilence. If they did move around in immense herds like birds, maybe
they ate themselves to the point of a large die-off and the survivors died
from diseases and from scavenging all the putrid meat. <

The third and last theory involves Evolution. The Dinosaurs evolving
into birds. This theory first was postulated in the mid 1900th century
and later by Bob Bakker and Jack Horner.
