Jurassic Park II
ACT I
Dinosaurs were lords of the Earth for more than 200 millions years. Their supremacy was uncontested...
But 65 millions years ago, dinosaurs suddenly died. They all disappeared in a few years!
Why, only dinosaurs disappeared? when mammals, birds, insects and above all lots of reptiles stay alive! Why did dinosaurs disappear all at once?
All sorts of explanations have been made to explain dinosaurs' end- epidemic, climate change, competition with mammals volcanic explosion and the meteorite one. And lately some say, dinosaurs were too fat to move quickly to feed and fend themselves...
Personally, I don’t believe any of the above explanations.

Probably, only we would know the answer of the above. The answer would be as follows:
Humans civilization, in its progression, went through stone age, bronze age and iron age. Iron provided teeth and claws to this dinosaur in making. Towards the later part of the iron age, he found a black liquid substance, called crude oil, which proved to be an easy source of energy. There was no looking back for him after that discovery. For all his energy needs there was this answer – OIL. Oil became an integral part of his life. He started growing in size, volume, strength and speed. Using jumbo jets, mammoth ships, giant cranes and huge machines he built sky scrappers, bridges, tunnels, roads etc. He controlled climate using the same easy energy source. He also made lethal weapons and sophisticated nuclear warheads.
Now he could not think of a life without this natural resource. The ease of using this resource, resulted in its wasteful use in copious quantities. Soon, this substance became scares and came at the verge of exhaustion in the womb of mother earth.
…And this was the time, man took arms against man. There were fight for possession of oil fields. Man became man’s enemy. Third world war resulted. Nuclear warheads were used. Most of their population was wasted in this war for oil. Few remained after the war, but due to exposure to nuclear radiation these men were not able to reproduce and it was matter of time that dinosaur II, disappeared from the face of this earth…
============
Now, I think I have an answer for dinosaur-I’s extinction.
I guess, in their last days, they got used to some natural resource, which slowly exhausted from the earth, as oil in our case. And there was a big fight among these dinosaurs for its possession. Weaker dinosaurs were eliminated. And among the stronger dinosaurs, the weaker sex. The earth was left with similar sex dinosaurs, which could not reproduce and hence became extinct.

SOunds very unlikely from a simple evolutionary point of view, unlesss the resource was went from comon to zero in one generation then there would be a strong evolutionary pressure for the male dinosaurs to give food to the female ones as the ones that did this would have children....

Could it not have been something to do with increased egg predation by the growing population of mammals?

A new giant species of Repenomamus (a triconodont mammal from the Early Cretaceous) has been found in China complete with stomach contents comprising juvenile Psittacosaurus. The new species may have been about 1 metre in length. This is the first evidence we have that mesozoic mammals preyed on dinosaurs.
Interesting thought...

The end of the Cretacious period, was a time of great extinction. Many species of plants and animals became extinct. Since the dinosaurs were the dominant animals of the land, they lost the most species, and became extinct.
Today we are also in another great extinction. Plants and animals are becoming extinct at a rate arguably higher than at the end of the Cretaceous period. Man is the dominant species on the earth...

And your point is?? Homo Sapiens are about to become extinct??
All the great extinctions can be correlated with natural catastrophes- of which there are plentiful possibilities- asteroids, supervolcanoes, release of sub-sea methane hydrates...

Extinction is a natural process. When the environment changes more rapidly than species can adapt, the species must adapt or die out.
We make a big deal out of some cute little guppy in a brook that only one person in a hundred can visit but we ignore the natural extinction of insects we consider pests.
If we go extinct, I'm sure the world will be a more highly evolved place.

The whole of mankind seems preoccupied with gods, human superiority, and
the apocalypse. This hypothesis only seems to me to be an amalgamation of the latter two. In the 19th and early 20th centuries mankind in what is now "developed" countries were faced with the disappearance of another natural resource: Wood. I don't see that as being much of a crisis anymore, because we have found a way to live without demolishing our reserves of the stuff. Even if we run out of oil we will only switch to the second most readily available resource. Unfortunately, oil does not replenish itself nearly as quickly as wood, but I believe we will nevertheless be fine. After all, the one defining characteristic of man and animal is the ability to survive.
