Why Did the Dinosaurs Become Extinct?

By Anthony Starks


What has happened to the dinosaurs? This is a question most of us might have asked. Anyone who has observed the blockbuster science fiction film Jurassic Park focused by Steven Spielberg would have definitely wondered what truly happened to the dinosaurs. There are many facts contributing to their own rapid extinction. Although a lot of reasons have been attributed for the extinction, we're yet to figure out the real fact behind the actual rapid disappearance of dinosaurs from the earth.

The dinosaurs are generally vertebrate animals that are seen to be existed in planet for over 160 million years ago. It has been said that the dinosaurs first appeared in our land 230 trillion years ago. According to present facts it is considered that the dinosaur games pertaining to 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 subjects of the raining meteors. The meteor attack was not fully an incidental event. The attack will need to have happened suddenly and they would have found it difficult to hightail it from the calamity. Nevertheless the readings of the past suggest that the mass extinction was not a rapid process. It would are actually gradual over five million years.

There exists another theory that states that the dinosaurs ended up hit by an extremely cold wave in the prehistoric time. Your cold wave should have been resulted from the changes in the earths orbit. Planet earth was not very warm at that time. So it is been said that most of the pets in earth like the dinosaurs did not have enough time to gone pass a thorough progression process. There were not many hairs over their and they were not able to face up to the extreme cold weather. Their physical components were limited and therefore could not survive the extreme weather. So they had been forced to collapse to the floor.

The third popular theory is the one that affirms that dinosaur names faced a great risk for his or her lives and were burnt to ashes due to the extreme volcanic activity and also the subsequent acid rainwater. They were huge mammals and were unable to avoid the natural disaster. Your delayed Cretaceous was a period when many higher tectonic action and volcanic actions has taken place. The particular super continent has been splitting paving approach to new continents, and thus global cooling occurred. This led to bulk extinction.

There are also values that the dinosaurs must have sunken and drowned in a mass tsunami. The pressure and the effect from the tsunami are usually unpredictable. Consequently there are chances the creatures must have disappeared into the water outbreak as they were at risk of such mass unfortunate occurances. Yet another saying moves that scarcity with the food led to dinosaurs combating with each other thereby eliminating each other. The poor ones died involving hunger an a variety other mammals started out eating dinosaur eggs with regard to survival. Moreover, in addition there are chances that the dinosaurs should have fought among by themselves for establishing territorial wins.

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