Dinosaur-2

Fight between two Dinosaurs

The creation of the earth is also very astonishing, a piece of burning fire-ball suddenly came out from the sun and set-up on orbit and has been rounding Sun like other Planets. That fire-ball is our earth; millions of years were taken to be cold and solid of that fire-ball.

Since from the sign of life on the earth, so many creatures were born to pre-historical age and their existences were continued millions of years. Once they were abolished from the earth due to natural calamities or external force affected ecological balance of the earth like comet falling or piece of other planet falling. Thus several eras were destroyed with the entities of creatures. Most of them are still unknown to us as we did not find out any sign of their existence of the time of archaeological searching.

Jurassic era was one of the most significant of the earth. This era was the pre-historical age. At this time the entire earth would consider one continental .Thereafter, within Cretaceous era, the entire earth was reformed and divided into various pieces of continentals and sub-continentals. This is story of sixty to seventy millions of years ago. Human being came on the earth after many years through step by step evolution.

One most significant of the Jurassic age was that most of the animals were huge tall and gigantic figures like dinosaurs. The average heights of the dinosaurs were sixty to seventy fits. They were very furious and some of them were carnivores too. They would never mercy their enemies and thus often serious and destroy able fight would take place among them. Theropod dinosaurs were very much furious and carnivore. They would normally ninety fits in height and they would often hunt the weaker section of the animals for their food.

We also get the sign of one kind of dinosaur that had wings and looked like big size of bird. They most probably called Theropod group of the dinosaur. It says that birds have four-chambers of heart like Theropod dinosaurs.  Since the 1990, lost of feathers-dinosaurs fossils were discovered that proves the connection between dinosaurs and modern birds. They were available just about sixty-six millions of years ago.

Dinosaurs were not mammal class animals. They would lay eggs in-communal places. The shells of those eggs would very hard as made of calcium carbonate. They would lay pair of eggs at a time and the male dinosaurs would primarily hatch those eggs. There are some opinion that dinosaurs did not care about eggs and kids. But this is was not fully authentic; because, dinosaurs' nests and eggs are found at north western side of Scotland, which proves that dinosaurs were also few bits would take care.

As per the law of nature, nothing is ever lasting in this earth. Dinosaurs were also covered under this nature-law.  Once natural calamities were come and the entire creatures of that time were abolished from the earth. There are so many opinions about their abolishing; some says that suddenly a big and huge comet falling is the reason of their abolishing; some says that often reformation of the earth is the reason, some says that food crisis is the reason, some says that fundamental changes of  nature is the reason. I say that, reason may be one of these or altogether; the fact is dinosaurs did not survive.
