A number of different theories have been assessed throughout the course
of this research to attempt to reach a conclusion as to the reason
behind the extinction of the Tyrannosaurus Rex. Although all arguments
are credible, and supportive with educated information and data, the
most conclusive theory of all is The Alvarez Asteroid Impact theory.
Alvarez, a researcher at the University of California, discovered a
pencil thin layer of Iridium around the rocks in Gubbio, Italy. (New
Scientist, 1) Iridium is an element found in meteorites and asteroids.
In 1980 it was proven that the layer if Iridium was evidence of a huge
comet or meteorite that crashed into the earth sixty five million years
ago. The normal amount of Iridium an area is to have is 0.001 on an
average. The layer of Iridium found in Gubbio Italy was 0.003. Thirty
times the average amount in parts per million. (New Scientist, 1) The
theory of the Alvarez Asteroid states that the strength of this comet is
at 10,000 times the explosive power of the global nuclear arsenal. The
Alvarez Asteroid theory is the leading explanation as to why the amazing
dinosaur creatures died millions of years ago, along with many other
animals of the Earth's Crustaceous Period.
The extinction of
the Tyrannosaurus Rex was obviously due to the same reason. Every other
living species was killed sixty five million years ago. Although it is
