Dinosaur Extinction
'''

Up until recently the K-T Theory (Impact Theory) has been the most popular theory as to why the dinosaurs became extinct, however, newly discovered evidence has proved this to be wrong and a new theory has been developed and is seemingly more plausible. This is the Ectothermic Theory, the idea that dinosaurs had "mental disorders, including a decrease in brain size". Link to quote.

K-T Theory
'''

The K-T Theory is a bold suggestion, it is the concept the a meteorite (6 miles in diameter) impacted the earth and in turn the planet was covered with dust and debris as such which prevented sun light for many years. In turn links in the food chain weakened and broke as animals had less and less to eat, the dinosaurs are only some of the animals that died. Fact is their has been no fossil found to support this event at all, hence there has been considerable resistance from paleontologists. Leo Hickey of Yale University commented that the patterns of different survival and extinction were inconsistent with the notion of catastrophic extinction. For instance, tropical plants, which would be expected to suffer the most during several years of global darkness, actually were only moderately affected by the extinction. It can contrast, temperate plants were devastated, in spite of the actual fact that temperature plants can suffer through periods of reduced sunlight better than tropical plants. Studies have been taken and only 4% of paleontologists were convinced by the Impact Theory was true.

Ectothermic Theory

These Ectothermic beasts were cold-blooded, sluggish, slow and generally dumb. http://www.oakton.edu/user/~billtong/eas100/dionsaur.htm Recent discoveries have shown that dinosaurs had "mental disorders", this lead to a lack of consciousness and ability to change behavior patterns, in effect they were unable to compete in the competitive world they lived in. Their size was highly significant, but they could not take advantage of this. Also their movability was very limited a "recent estimate suggests that an average person might have been able to out run an adult Tyrannosaurus, Usain Bolt has reached 53.11 kmh or 33 mph much faster then any dinosaur could ever run. Because they lacked speed, dinosaurs were easy prey for predators that travelled in herds. In fact the word dinosaur means " terrible lizard" relating back to its limitations mentioned above. http://www.dinosaurs-video.blogspot.com/2010_07_01_archive.html
