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 watched the blockbuster sci-fi film Jurassic Park aimed by Steven Spielberg would have definitely wondered what actually happened to the dinosaurs. There are numerous facts contributing to their rapid extinction. Although many reasons have been paid for the extinction, we are yet to figure out the actual fact behind your rapid disappearance of dinosaurs through the earth.

The dinosaurs are vertebrate animals that are seen to be existed in globe for over 160 trillion years ago. It has been said that this dinosaurs first appeared about our land 230 million years ago. According to present facts it is thought that the dinosaur games with regard to kids became extinct by the end with the Cretaceous period, about Sixty five million years ago. One of the most popular reasons being mentioned is that the dinosaurs had become the patients of the raining meteors. The particular meteor attack was not entirely an incidental function. The attack will need to have happened suddenly and they'd have found it difficult to run away from the calamity. However the readings of the fossils suggest that the size extinction was not an abrupt process. It would happen to be gradual over 10 million years.

There are also values that the dinosaurs must have enveloped and drowned inside a mass tsunami. The force and the effect in the tsunami are usually unpredictable. So there are chances that the creatures must have gone away into the water outbreak as they were at risk of such mass disasters. Yet another saying should go that scarcity of the food led to dinosaurs battling with each other thereby killing each other. The weak ones died associated with hunger an a variety other mammals started out eating dinosaur eggs for survival. Moreover, there's also chances that the dinosaurs must have fought among by themselves for establishing territorial advantages.

The third popular theory is the one that affirms that dinosaur names faced a great risk because of their lives and have been burnt to ashes due to the extreme volcanic activity and the subsequent acid rain. They were huge animals and were unable to escape from the natural disaster. The particular delayed Cretaceous was a occasion when many substantial tectonic action and volcanic actions has taken place. The super continent ended up being splitting paving approach to new continents, and thus global cooling came about. This led to mass extinction.

There exists another theory which states that the dinosaurs had been hit by a very cold wave in the prehistoric time. Your cold wave will need to have been resulted through the changes in the earths orbit. The earth was not very cozy at that time. So it is been postulated that most of the animals in earth such as dinosaurs did not have enough time to proceeded to go pass a thorough progression process. There were few hairs over their and they were not able to withstand the extreme cold weather. Their physical attributes were limited and therefore could not survive the ultimate weather. So they have been forced to collapse to the ground.

The fact behind dinosaurs' disintegration is still ambiguous. However it is true that the dinosaurs have become a real topic of curiosity for the movie makers.
