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 observed the blockbuster science fiction film Jurassic Park led by Steven Spielberg would have absolutely wondered what really happened to the dinosaurs. There are numerous facts contributing to their particular rapid extinction. Although a few reasons have been attributed for the extinction, we have been yet to figure out the real fact behind your rapid disappearance of dinosaurs in the earth.

The dinosaurs are vertebrate animals that are discovered to be existed in earth for over 160 trillion years ago. It has been said how the dinosaurs first appeared about our land 230 trillion years ago. According to existing facts it is believed that the dinosaur games regarding kids became extinct by the end from the Cretaceous period, about 65 million years ago. One of the most common reasons being mentioned is that the dinosaurs had become the sufferers of the raining meteors. The actual meteor attack was not fully an incidental function. The attack must have happened suddenly and they might have found it difficult to hightail it from the calamity. Even so the readings of the fossils suggest that the mass extinction was not a rapid process. It would are actually gradual over 15 million years.

There are also beliefs that the dinosaurs must have immersed and drowned in the mass tsunami. The push and the effect from the tsunami are usually unpredictable. Consequently there are chances that this creatures must have disappeared into the water break out as they were at risk of such mass disasters. Yet another saying should go that scarcity with the food led to dinosaurs combating with each other thereby killing each other. The poor ones died associated with hunger an a variety other mammals began eating dinosaur eggs regarding survival. Moreover, additionally, there are chances that the dinosaurs must have fought among by themselves for establishing territorial wins.

The third popular principle is the one that claims that dinosaur names faced a great risk for lives and have been burnt to ashes as a result of the extreme volcanic activity and also the subsequent acid bad weather. They were huge mammals and were unable to get away from the natural disaster. The delayed Cretaceous was a time when many high tectonic action and volcanic action has taken place. Your super continent had been splitting paving approach to new continents, and for that reason global cooling happened. This led to mass extinction.

There is another theory that states that the dinosaurs were hit by a very cold wave through the prehistoric time. Your cold wave should have been resulted from the changes in the earths orbit. Our planet was not very comfortable at that time. So it is been postulated that most of the wildlife in earth such as dinosaurs did not have enough time to travelled pass a thorough development process. There were few hairs over their and they were not able to stand up to the extreme cold climate. Their physical qualities were limited thus could not survive the ultimate weather. So they had been forced to collapse down.

The fact behind dinosaurs' annihilation is still ambiguous. But it's true that the dinosaurs have become a real topic appealing for the movie makers.
