Science Fiction Story: Meteor that fell to earth, the cause of the extinction of Dinosaurs

Suppose a large asteroid or meteor does not fall to hit the earth. Perhaps modern humans also do not exist today. Because the current human being who controls all living things on Earth.

About 66 million years ago, a large asteroid fell and hit the earth. It caused a very powerful tsunami of the ocean and a very strong earthquake. It even triggered a great fire. But the damage is not a big deal on Earth. The crush of the earth is the collision of a falling meteor.

Some of the earth's enormous surface material is even thrown into the air and drops back into acid rain. But the most fatal is the dust that throws into the stratosphere and continues to be there. It prevents sunlight from entering Earth. Like the dust from a volcanic eruption, it throws to a very high place and settles on the surface of the sky.

The Earth suddenly becomes cold a few tens of degrees Celsius. Earth was darker and the impact of the plant difficult to do photosynthesis until it does not develop.

When large animals do not get enough food and some die. Because plants begin to lack of sunlight, and its growth is even less extinct.

Suppose the giant size meteor did not fall to earth, or fall before and after the Dinosaur era or did not happen.

The impact can be different for humans today. Researchers say humans are not necessarily present on earth as it is now. That is, superior animals may be superior to the presence of humans and they remain in the top rankings. And predators when antiquity was dinosaurs as the greatest creatures.

Perhaps also the current food chain will change and more diverse. Again, it is not the human being at the top.
There are dinosaurs in the food chain. Mammal creatures certainly will not be able to grow more, because of the colony of colonies of giant animals.

It is estimated that the meteor that falls on the Yucatan peninsula makes a crater pit known as Chicxulub with a size of 124 miles with a depth of 12 miles. Meteor collisions with the earth erase 80% of the species on earth. Flying dinosaurs are dead, but winged species can still live. And become the ancestors of birds today. The rest may be like the Komodo dragons are the remains of ancient animals, and others shrunk into giant lizards only.

The meteor that falls in the tangla bay deploys a large amount of sulfur from flee to the atmofer. Ben Garrod one of The Day The Dinosaur's peresenter died, the obscure rock locked the fate of ancient animals. If the asteroid falls in the Pacific or Atlantic oceans, dinosaurs may survive this disaster.
The reason, when falling in the sea, means there are no pieces of stone fragments that are thrown into the space atmofer.

The meteor explosion in the crater is 10 million times larger than the bomb in Hiroshima. The extinction of the dinosaurs is estimated to begin to occur 66 billion years ago.
