Dinosaurs: Extinct or Not?

By Anthony Starks


What has really happened to the dinosaurs? This is a question most of us would've asked. Anyone who has observed the blockbuster sci-fi film Jurassic Park aimed by Steven Spielberg would have certainly wondered what really happened to the dinosaurs. There are many facts contributing to his or her rapid extinction. Although a few reasons have been credited for the extinction, we have been yet to figure out the real fact behind the actual rapid disappearance of dinosaurs from your earth.

The dinosaurs tend to be vertebrate animals that are seen to be existed in earth for over 160 thousand years ago. It has been said how the dinosaurs first appeared upon our land 230 trillion years ago. According to current facts it is considered 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 common reasons being cited is that the dinosaurs had become the victims of the raining meteors. The particular meteor attack was not totally an incidental celebration. The attack should have happened suddenly and they would have found it difficult to run away from the calamity. Though the readings of the fossils suggest that the bulk extinction was not a rapid process. It would have been gradual over five million years.

There are also values that the dinosaurs must have sunken and drowned in a mass tsunami. The drive and the effect in the tsunami are usually unpredictable. Consequently there are chances that this creatures must have disappeared into the water break out as they were susceptible to such mass catastrophes. Yet another saying moves that scarcity in the food led to dinosaurs combating with each other thereby killing each other. The poor ones died associated with hunger an also some other mammals started eating dinosaur eggs for survival. Moreover, additionally, there are chances that the dinosaurs have to have fought among on their own for establishing territorial advantages.

The third popular theory is the one that says that dinosaur names faced a great risk for their lives and have been burnt to ashes because of the extreme volcanic activity and also the subsequent acid rainfall. They were huge animals and were unable to get away from the natural disaster. The actual delayed Cretaceous was a moment when many large tectonic action and volcanic action has taken place. The particular super continent was splitting paving strategy to new continents, and thus global cooling happened. This led to size extinction.

There is certainly another theory that states that the dinosaurs have been hit by an exceptionally cold wave through the prehistoric time. Your cold wave have to have been resulted from your changes in the earths orbit. Our planet was not very hot at that time. So it is been said that most of the creatures in earth including the dinosaurs did not have enough time to went pass a thorough advancement process. There were few hairs over their own health and they were not able to stand up to the extreme cold weather. Their physical attributes were limited thus could not survive the ultimate weather. So they were forced to collapse down.

The fact behind dinosaurs' annihilation is still ambiguous. Yet it's true that the dinosaurs are becoming a real topic of great interest for the movie makers.
