| 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.
