Why Did the Dinosaurs Become Extinct?

By Anthony Starks


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

The dinosaurs tend to be vertebrate animals that are discovered to be existed in globe for over 160 zillion years ago. It has been said that this dinosaurs first appeared on our land 230 zillion years ago. According to present facts it is belief that the dinosaur games with regard to kids became extinct by the end of the Cretaceous period, about 65 million years ago. One of the most popular reasons being reported is that the dinosaurs had become the sufferers of the raining meteors. The actual meteor attack was not totally an incidental event. The attack have to have happened suddenly and they would have found it difficult to hightail it from the calamity. Though the readings of the fossils suggest that the size extinction was not a rapid process. It would are actually gradual over 10 million years.

There's another theory in which states that the dinosaurs were hit by an exceptionally cold wave during the prehistoric time. The particular cold wave will need to have been resulted from your changes in the earths orbit. The planet earth was not very cozy at that time. So it is been postulated that most of the creatures in earth like the dinosaurs did not have enough time to went pass a thorough development process. There were only a few hairs over their bodies and they were not able to stand up to the extreme cold climate. Their physical qualities were limited and hence could not survive the extreme weather. So they had been forced to collapse down.

The third popular idea is the one that affirms that dinosaur names faced a great risk for lives and have been burnt to ashes because of the extreme volcanic activity as well as the subsequent acid rain. They were huge mammals and were unable to escape from the natural disaster. The actual delayed Cretaceous was a moment when many higher tectonic action and volcanic action has taken place. The super continent ended up being splitting paving approach to new continents, and thus global cooling occurred. This led to muscle size extinction.

There are also thinking that the dinosaurs must have enveloped and drowned inside a mass tsunami. The pressure and the effect of the tsunami are usually unpredictable. So there are chances how the creatures must have faded into the water episode as they were prone to such mass unfortunate occurances. Yet another saying moves that scarcity with the food led to dinosaurs preventing with each other thereby eliminating each other. The fragile ones died associated with hunger an also some other mammals began eating dinosaur eggs with regard to survival. Moreover, there's also chances that the dinosaurs will need to have fought among themselves for establishing territorial wins.

The true reason behind dinosaurs' termination is still ambiguous. But it is true that the dinosaurs are becoming a real topic of great interest for the movie makers.
