Theories on the Extinction of the Dinosaurs

By Anthony Starks


What has happened to the dinosaurs? This could be a question most of us would have asked. Anyone who has observed the blockbuster science fiction film Jurassic Park aimed by Steven Spielberg would have surely wondered what genuinely happened to the dinosaurs. There are numerous facts contributing to their own rapid extinction. Although a few reasons have been paid for the extinction, were yet to figure out the actual fact behind the rapid disappearance of dinosaurs from your earth.

The dinosaurs are usually vertebrate animals that are discovered to be existed in world for over 160 zillion years ago. It has been said the dinosaurs first appeared upon our land 230 trillion years ago. According to existing facts it is believed that the dinosaur games with regard to kids became extinct by the end from the Cretaceous period, about Sixty five million years ago. One of the most common reasons being reported is that the dinosaurs had become the victims of the raining meteors. The particular meteor attack was not fully an incidental occasion. The attack must have happened suddenly and they would have found it difficult to hightail it from the calamity. However the readings of the fossils suggest that the mass extinction was not an abrupt process. It would have been gradual over ten million years.

There's another theory in which states that the dinosaurs were hit by an extremely cold wave throughout the prehistoric time. The particular cold wave have to have been resulted from your changes in the earths orbit. Planet earth was not very warm at that time. So it is been said that most of the animals in earth such as the dinosaurs did not have enough time to travelled pass a thorough development process. There were only a few hairs over their health and they were not able to face up to the extreme cold climate. Their physical components were limited thus could not survive the ultimate weather. So they ended up forced to collapse to the floor.

The third popular idea is the one that says that dinosaur names faced a great risk for their lives and were burnt to ashes because of the extreme volcanic activity and the subsequent acid rain. They were huge animals and were unable to avoid the natural disaster. The actual delayed Cretaceous was a time when many substantial tectonic action and volcanic activity has taken place. Your super continent had been splitting paving strategy to new continents, and as a result global cooling came about. This led to muscle size extinction.

There are also thinking that the dinosaurs must have immersed and drowned inside a mass tsunami. The pressure and the effect in the tsunami are usually unpredictable. So there are chances how the creatures must have gone away into the water break out as they were vulnerable to such mass unfortunate occurances. Yet another saying will go that scarcity in the food led to dinosaurs preventing with each other thereby eliminating each other. The weak ones died regarding hunger an a variety other mammals began eating dinosaur eggs regarding survival. Moreover, there are also chances that the dinosaurs will need to have fought among by themselves for establishing territorial victories.

The true reason behind dinosaurs' annihilation is still ambiguous. However it is true that the dinosaurs have grown to be a real topic of great interest for the movie makers.
