Dinosaur Extinction Essay examples -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  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.   Ã‚  Ã‚  Ã‚  Ã‚  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.   Ã‚  Ã‚  Ã‚  Ã‚  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 believed that the asteroid theory is the cause of extinction of the Crustaceous Period, we cannot be positive. The environmental effects of this problem were that the dinosaurs living during this period perished from the earth and their extinction remains a mystery to us to this day. All we can do to reenact what happened is use the technology we have in the twenty first century to find more evidence to see what went wrong so long ago. By discovering things like what happened to the Tyrannosaurus Rex we can use this information to prevent an event such as a mass extinction from happening a second time.   Ã‚  Ã‚  Ã‚  Ã‚  Although it is impossible to rewrite history, we still have to be careful to prevent a catastrophe like the asteroid said to have hit the earth sixty five million years ago. If there is ever a scare of an asteroid as big as the Alvarez Asteroid, one way of preventin... ...d at least seven tons and were over forty feet long. The T-Rex was the largest meat-eating dinosaur. The teeth of the T-Rex are thick and sharp for the killing of its prey. The T-Rex was also very fast; in fact it could outrun any species of dinosaur if it was hungry enough. Scientists have also found that the Tyrannosaurus was also very smart, it would outwit any prey if it needed a snack, even the Gigantosaurus the only dinosaur that is bigger than the T-Rex wasn't smarter than the king. (Highlights, 22)   Ã‚  Ã‚  Ã‚  Ã‚  The Tyrannosaurus Rex was a very smart and interesting dinosaur and it is unfortunate that we will never be able to see one. The extinction of dinosaurs was brought on by the Alvarez Theory. It is great to know what actually happened to them now, and also know how to prevent such an occurrence from happening again. If our country uses the technology it has available it will be possible to find out more about the mass extinction of the Crustaceous Period. As the years pass technology becomes more advanced and we will eventually know everything there is to know about what happened sixty five million years ago.   Ã‚  Ã‚  Ã‚  Ã‚
