Unproven Beliefs on the Extinction of Dinosaurs

By Anthony Starks


What has really happened to the dinosaurs? This is a question most of us might have asked. Anyone who has seen the blockbuster sci-fi film Jurassic Park aimed by Steven Spielberg would have absolutely wondered what truly happened to the dinosaurs. There are numerous facts contributing to their own rapid extinction. Although some reasons have been acknowledged for the extinction, we have been yet to figure out the true fact behind the actual rapid disappearance of dinosaurs from the earth.

The dinosaurs are generally vertebrate animals that are discovered to be existed in earth for over 160 trillion years ago. It has been said the dinosaurs first appeared about our land 230 million years ago. According to present facts it is considered that the dinosaur games for kids became extinct by the end with the Cretaceous period, about Sixty five million years ago. One of the most popular reasons being specified is that the dinosaurs had become the victims of the raining meteors. The meteor attack was not completely an incidental occasion. The attack have to have happened suddenly and they would have found it difficult to hightail it from the calamity. Even so the readings of the fossils suggest that the bulk extinction was not a sudden process. It would have been gradual over 15 million years.

There are also morals that the dinosaurs must have submerged and drowned inside a mass tsunami. The drive and the effect of the tsunami are usually unpredictable. Consequently there are chances that this creatures must have vanished into the water outbreak as they were susceptible to such mass disasters. Yet another saying moves that scarcity in the food led to dinosaurs battling with each other thereby eliminating each other. The vulnerable ones died regarding hunger an also some other mammals commenced eating dinosaur eggs regarding survival. Moreover, there's also chances that the dinosaurs should have fought among by themselves for establishing territorial wins.

The third popular theory is the one that claims that dinosaur names faced a great risk because of their lives and had been burnt to ashes on account of the extreme volcanic activity along with the subsequent acid rain. They were huge animals and were unable to escape from the natural disaster. The actual delayed Cretaceous was a period when many higher tectonic action and volcanic motion has taken place. The super continent had been splitting paving method to new continents, and consequently global cooling occurred. This led to mass extinction.

There is certainly another theory that will states that the dinosaurs had been hit by an extremely cold wave throughout the prehistoric time. The particular cold wave must have been resulted from the changes in the earths orbit. The earth was not very comfortable at that time. So it is been postulated that most of the creatures in earth such as the dinosaurs did not have enough time to proceeded to go pass a thorough development process. There were few hairs over their bodies and they were not able to resist the extreme cold weather. Their physical attributes were limited and therefore could not survive the ultimate weather. So they were forced to collapse to the floor.

The fact behind dinosaurs' termination is still ambiguous. But it is true that the dinosaurs have become a real topic of interest for the movie makers.
