Prehistoric Creatures: Vanished from the Earth

By Anthony Starks


What has really happened to the dinosaurs? This would be a question most of us would have asked. Anyone who has viewed the blockbuster sci-fi film Jurassic Park focused by Steven Spielberg would have certainly wondered what truly happened to the dinosaurs. There are many facts contributing to their particular rapid extinction. Although many reasons have been acknowledged for the extinction, we are yet to figure out the fact behind the actual rapid disappearance of dinosaurs from your earth.

The dinosaurs are vertebrate animals that are discovered to be existed in globe for over 160 thousand years ago. It has been said that this dinosaurs first appeared in our land 230 trillion years ago. According to present facts it is belief that the dinosaur games with regard to kids became extinct by the end from the Cretaceous period, about 65 million years ago. One of the most popular reasons being mentioned 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 might have found it difficult to hightail it from the calamity. Though the readings of the fossils suggest that the mass extinction was not a sudden process. It would happen to be gradual over 10 million years.

There are also beliefs that the dinosaurs must have submerged and drowned in the mass tsunami. The push and the effect of the tsunami are usually unpredictable. Therefore there are chances how the creatures must have gone away into the water outbreak as they were at risk of such mass unfortunate occurances. Yet another saying moves that scarcity from the food led to dinosaurs battling with each other thereby killing each other. The vulnerable ones died associated with hunger an a variety of other mammals commenced eating dinosaur eggs pertaining to survival. Moreover, additionally, there are chances that the dinosaurs must have fought among them selves for establishing territorial victories.

The third popular idea is the one that claims that dinosaur names faced a great risk for his or her lives and were burnt to ashes because of the extreme volcanic activity as well as the subsequent acid rainfall. They were huge animals and were unable to get away from the natural disaster. The delayed Cretaceous was a period when many high tectonic action and volcanic motion has taken place. Your super continent ended up being splitting paving approach to new continents, and consequently global cooling occurred. This led to bulk extinction.

There is another theory that will states that the dinosaurs had been hit by an exceptionally cold wave throughout the prehistoric time. The cold wave should have been resulted from the changes in the earths orbit. The planet earth was not very cozy at that time. So it is been said that most of the wildlife in earth like the dinosaurs did not have enough time to travelled pass a thorough development process. There were few hairs over their bodies and they were not able to withstand the extreme cold weather. Their physical components were limited so because of this could not survive the extreme weather. So they had been forced to collapse to the floor.

The fact behind dinosaurs' annihilation is still ambiguous. But it's true that the dinosaurs are getting to be a real topic of interest for the movie makers.
