How dinosaurs disappeared?

Answer 1

the evolutionists will not agree with this, but there is a very good likely hood that the majority of the dinosaurs became extinct during what the Bible refers to as the "Flood of Noah".

Dinosaurs were evidently around in numbers in the Old Testament and were referred to as "Behemoths" having large tails that could sweep attackers away with prior to the "Flood of Noah"

Answer 2

The latest NOVA programs point at a supervolcano as the likely culprit. Another possibility is a massive comet hitting the Earth. So far, they are just theories backed by certain evidence, including ash layers that include high sulphur content (supervolcano would have deposited such a layer).

One supervolcano currently under scrutiny by the USGS for extra current activity is the caldera under Yellowstone Park area.

Answer 3

Many theories have evolved. here are a few: the asteroid collision, the weather change, the abundance of mammals which consumes eggs of dinosaurs and the nemesis hypothesis: every 26 million years, there will be a comet crashing on Earth.

Answer 4

A huge spaceship collided with Earth. It had been hijacked by the Cybermen and brought back through time, by accident. When it collided it created such an explosion and it threw up so much dust that the Earth was covered in dust, blocking out the sun for more than 50 years. Almost all life was extinguished.

Answer 5

They smoked cigarettes, drove without seatbelts, ate fatty foods, practiced freelove and trusted their politicians with lifetime office. Or maybe it was a continual spiral of factors including meteor/comet collisions, solar flares, super volcanos, plate tectonic shifts, disease and climate changes, that causes a thing called "evolution"?

Answer 6

some say giant meteor
some say volcanic ash blanked the globe blocking out the sun
or the earth flipped 180 degrees causing catastrophic events
global flood or severe change in climate (ice age)

Answer 7

They went away in a poof of smoke.

Answer 8

A new theory about Extinction of Dinosaurs. The theory of the increasing of the earth's gravity.
From the earliest days that the big bones of past animals were found, some questions about their decline came up, which continued up to this day. By observing the fossils of giant dinosaurs, about several million years ago, this question comes up that, which factors caused them to decline?

Scientist has made many efforts to answer this question, and they suggested many theories in this case. Theories like the outbreak of diseases, decreasing food and eating of their eggs by other smaller mammals.

Among these theories, there is one theory which is of more acceptance for scientists and attracts the attention of more acceptance for scientists and attracts the attention of most people, this theory which came up by two American geologists from California’s university (Berkeley), Luis Alvarez and his son Walter at recent years of seventh decade, is about the collision of meteorite with earth. This theory says that: A rock with 10-15km diameter and about one thousand billion ton weight, with 150 thousand km/h entered earth's atmosphere and friction of this giant rock on the air caused the sublimation of its outer layers. Four or five seconds later the big core of this big meteorite collided the surface of sea and made a big wave with height of 1km. This wave was distributed on the oceans and cover seashores. Collision of meteorite sent a mixture of steam and dust and stones on the earth. All of these stems, smokes and dusts made a big curtain on earth and for several months or perhaps years the earth was in an absolute dark. These events occurred about 65 million years ago and declined dinosaurs.

If the decline of animals was related to a special period, it was possible to rely on this theory, but as we knew, animals at every time, have lost some species. Perhaps, at one time, these declines were very much, but in any case, declines were existed at every periods of time. If we accept that the collision of a giant meteor it with earth and formation of dust and smoke in 65 million years ago caused the decline of dinosaurs, how we can explain of Endocras with 4.5m diameter, about 500 million years ago. At that time did a giant meteorite collide with earth and declined them? Did another meteorite collide with earth 330 million years ago and declined Eogyrinus? Did the collision of meteorite, about 250 million years ago caused big insects to decline? In this case how we can explain the decline of Lepidodendrales plant, Calamitales and giant tree ferns. Did they was destroyed when a big meteorite collide the earth 300 million years ago. The decline of Macropustion and big Diprotodon in Australia, and decline of the awful bird, Phorohacos, which had a head as big as a horse's and length of 3/6m and big beak of 60cm, about 40 million years ago was because of the collision of meteorite? Did the decline of giant Dinornis maximus and Aepyornis maximus in these years was because of the collision of the big meteorite?

All of these shows that, such a theory can not explain declines animals during the long years. But there is another question, which shows the voidance of this theory! The question is that: assume that the big meteorite collide the earth 65 million years ago, and declined the big dinosaurs, why the remained reptiles couldn’t get bigger. The earliest reptiles, which were amphibious, were very small, but they could get bigger and made the dinosaurs. With the collision of didn't meteorite, dinosaurs was destroyed, but some of small reptiles survived. Why they make bigger animals!

Then, it becomes clear that, the factor, which caused them to decline, is still remained and doesn’t allow big reptiles to get bigger.

So, the collision of the big meteorite with earth and the formation of dust and smoke in atmosphere can not be supposed as the factor of dinosaurs' decline, because, that collision occurred at that time and the effect of dust and smoke have been disappeared and there was no later effect on animals.

Although the theory of the collision of the big meteorite and the formation of dust and smoke can not explain of the animals, but, at the same time, scientists hadn't made a mistake by suggesting this theory, in fact they are close to reality. Because in fact, decline of animals is some how related to meteorites, but not in a way that Luis Alvarez and his son explain.

The theory of the increasing of the gravity says that the fall of meteorites in long periods of time caused the gradual increase of earth, and by increasing of the gravity the ability of blood system of these animals decreased gradually. So those animals which had weaker blood system become smaller or declined. For this reason, after decline of dinosaurs, other reptiles couldn't get bigger, but small mammals which get stronger blood system were able to get their bodies bigger and made the big mammals of 20 million years ago. So, we see that, the scientists are not wrong, and they are right in thinking meteorites as an important factor in this phenomenon. But in the way of explaining and the quality of the extion of the meteorites, they are wrong. Scientists are looking for a big meteorite, which have been able to from such great dust and smoke on earth. But as we know it is not necessary to find a big meteorite, and small meteorites can also increase the gravity provided that their number is large.

People, who accept the theory of the collision of a big meteorite with earth, think that by revivaling the existing genes in the remained eggs of dinosaurs they can rebuild them, or by using the sperms of frozen Mammoth they can rebuild them. They think that the decline factor, which was the big meteorite, collided at the time and everything is finished, and they can form new giant animals. These scientist are unaware of the earth which they put their foots on it, and they don't as far the gravity of earth is like the gravity this time, it is impossible to revival such giant animals. Perhaps this is possible in Moon, the gravity of which is 1/6 of that of the earth.
