Dinosaurs ... is seen in the two hundred forty-five million years ago, and prosperity in sixty-five million years ago, the end of the Mesozoic reptiles. Dinosaurs suddenly disappeared in a given period, as the evolutionary history of life on Earth, a mystery, the fans still no one can answer it. Earth and the creatures are being recorded in the fossils. Mesozoic strata, which has found many dinosaur fossils. One can see the shape of a large number or variety of bones showing. However, in the immediate formation of the new generation, but not see dinosaur fossils. Thus infer the dinosaurs became extinct in the Mesozoic together.
On the real reason dinosaurs became extinct, ancient or Divergent, but they do not have a certain amount of argument thus far is still an unsolved puzzle study, in which only some of the more known argument are as follows :
Meteorite collision, said:
Sixty-five million years ago, a huge meteorite had hit the Earth, making thousands of monarchs of the earth up to one hundred million years of dinosaur extinction. This theory is from the University of California, Berkeley, Louis. Dr Al Balie Si four scientists suggested.
This is a huge meteorite, about ten kilometers in diameter. Because of the impact crater caused by the terrain, two hundred kilometers in diameter. Because of the impact on the energy, if converted into yellow powder, the equivalent of one hundred trillion tons (megaton). Spread of dust through the atmosphere into layers circle. Causing the planet to continue for a few months the dark state. During this period, the many species of dinosaurs have led lends extinction.
(1) Thunder Dragon:
Some of the huge dinosaur body, like the Thunder Dragon is one example. In the Jurassic, the Earth's climate is warm and humid, lush forests everywhere, because these rich plant foods, has brought prosperity herbivorous dinosaurs, Ray Long after this time are now active in North America plain.
Brontosaurus weight of about fifteen tons in three to fifty tonnes, it was sturdy legs, like tree trunks, like; long neck, straight up, there are seven buildings as high as can be said to have started the earth's largest animals. Ray Dragon's body is amazing though, temperament is very mild, usually temperate forest plants for food, sometimes into the marsh, with the buoyancy of the water, can reduce the heavy burden of its body, but also to avoid like the difference Trond-like carnivorous dinosaur violent attacks.
(2) Three lone Long:
Dragon Sword Dragon and the angle of the body plate and bone chip, can only be used as a passive defense, and can not do fight back, to a lonely dragon appears, the situation gradually changed. Three lonely lonely dragon dragon is the largest in size, his head with two spear-like horn, the other an angle between the processes in the eyes and nostrils. Such sharp weapons, even the most terrible it must be one-third of the dinosaur meat.
(3) Dragon Sword:
Appeared in one hundred and fifty million years ago, Stegosaurus, its greatest feature is the two ribs back arched panels, as well as students with sharp spines on the tail. Stegosaurus is a herbivorous dinosaur, slow, its body panels and tail bone on the tip of spine, has become the best defense to avoid the carnivorous dinosaurs.
(4) A dragon:
Stegosaurus had bony plates protect the body, but less than the local cover plate is still vulnerable to attack. Gradually disappeared when the Stegosaurus, the body dressed in a long bone plate (armadillo Long) will be replaced. A long tank like invulnerability, and even T. rex had no alternative to it.
(5) T. Rex:
Tyrannosaurus rex (T. rex) is the largest carnivorous dinosaurs, most brutal, the appearance time of Tyrannosaurus rex dinosaur age has been the most is the end of about eight million years from now. T. rex's body up to fourteen meters, weighs about ten tons, it is very thick rear strong, and can even hold up their rhinoceros.
From the T. rex fossil found that each of its teeth are as big as an adult's hand, even the eyes are bigger than the head. Although most of the body are staggering, but a pair of Tyrannosaurus rex forelimbs are small and short, short As there is no way to get even food into the mouth, the killer dragon and have the same habits of T. rex is very fierce animals.
〔6〕 duck guanlong:
Duck guanlong and Tyrannosaurus Rex, as seen in the end of the dinosaur era. Guanlong the most special place duck in the head, it was long, flat jaws, like a duck's mouth, so with such a name guanlong duck. Guanlong the past, people thought that the life and duck duck is similar to swimming in the water and to water plants for a living. Later, scientists found the time to duck guanlong fossil, they are not living to eat weeds, but trees to the shore for food, geese have the same habits guanlong.
1980 was preaching the story: a sunny afternoon, the sun shining under the tropical shrub forest, many different types and forms of the dinosaurs, as usual, quietly or stroll by the lake, or foraging in the water; the edge of the forest , a newly hatched eggs will survive in the duck-billed dinosaur egg nest was pacing back and forth; in the midst of open fields, and a Tyrannosaurus Rex is ready to swoop on a huge Triceratops ... ...
Suddenly, a loud noise has never been heard before broke the quiet of the world. A few kilometers in diameter meteor big bang into the Earth. This collision can be incredibly, the equivalent power of tens of thousands of atomic bomb explosion occurred in an instant. This is an unexpected asteroid collision with the Earth resulting from the impact force of up to 1015 tons TNT, the energy generated by the blast. Rolled up a huge mushroom cloud of dust rises quickly, straight into the sky, and then disperses, and finally to the entire planet is enveloped in it. Soon, the dinosaurs to see each other, because the dark clouds blotting out the sun during the day nor the sun. This situation lasted for a terrorist two years. Interrupt plant photosynthesis, and thus a large number of wither and die. So the vegetarian dinosaurs eat plants have died. After the meat of the dinosaurs are extinct because of the loss of food.
This story is asteroid asteroid caused mass extinction of dinosaurs theory of the essence. Later, many scientists continue to be given support. Some scientists even believe that the Earth has experienced during this period is not only a large planetary impact, but also by a number of times successively smaller, but still serious, life-threatening asteroid impact, which can confirm that the clothing in the Caribbean and the U.S. A Washington State found traces of collision of planets.
Evidence for this hypothesis came from all over the world also found in sediments 65 million years ago, the existence of an amino acid. This amino acid contains a lot of iridium, a large number of objects exist in some years, but on earth should not exist. This layer of iridium-rich strata in North America, Europe and Australia have discovered that many regions are in the Gun Region of Tibet, a few years ago also found in this layer containing iridium layer.
Some scientists believe that the explosion that all dinosaurs are extinct. But some scientists believe that only 70% of the extinction of dinosaurs at the time, some other dinosaur species are barely escaped the catastrophe, but in the next few million years and the gradual extinction. This latter claim is not unreasonable, because in 65 million years ago, after the incident in the formation of the strata, there are some dinosaur bones have been discovered. For example, the United States New Mexico 60 million years ago, for upper and lower strata was found in the wreckage of the dinosaurs. In the new generation of permafrost in Alaska, the also found fossils of Triceratops. These phenomena seem to indicate, in the asteroid colliding with Earth after the big bang caused, there are still some dinosaurs lived millions of years struggling to time, and finally as incompatible with the new climate and new environment and ultimately have become extinct.

如果恐龙是在瞬间灭绝的！那恐龙的化石周围应该还会别的动物的化石！
如果是小行星撞击的尘埃遮住那了太阳，那就会有大量植物死亡！那就会有大量的植物化石同时被发现！！可是事实不是这样的。
有一只恐龙进化成鸟了！这已经被大多数的科学家接受！
灭绝的这种说法本身就是错误的！
陨石撞击地球导致恐龙灭绝的说法也已经被科学家证明是错误的！
恐龙已经被证明是恒温动物！恐龙是冷血动物这种说法也是错误的！
科学家已经找到了长有羽毛的恐龙化石，这意味着什么？
上个世纪八十年代，英国的科学家在研究全球气候的时候，在北极厚厚的冰层下，钻取到了六千伍百万年前的古植物化石，英国的科学家感到非常的不解，为什么在六千伍百万年前还生长着茂密的森林，而现在却是冰天雪地，是什么导致地球的气候环境有如此大的改变？
普京当上俄罗斯的总统时，俄国的科学家给普京写了一份报告，建议总统将俄罗斯的核武器拿到月球上消毁，炸毁月球，这样就会使俄罗斯冰封的土地得以耕种，石油得以开采，不再是冰天雪地的俄罗斯，而是四季开满鲜花。俄罗斯之所以这样的寒冷，地球之所以有一年四季的交替，以及北极与南极这样的寒冷，都是月亮惹的祸，俄罗斯的科学家已经证明是月球的引力导致地球的偏移，从而使阳光不能均匀的照耀大地，从而导致地球上的气候环境有如此大的差异。
天文学家在研究月球起源时，有三种猜想，一：月球是地球的姐妹，他们是在太阳系时同时诞生的；二：月球是地球的女儿；三：月球是地球的妻子。当美国的载人宇宙飞船登上月球时，从月球上带回来的岩石测检的结果要比地球古老2亿年时，这将证明月球只能是地球的妻子。
美国的天文学家最新的研究报告指出，在六千五百万年左右太阳九大行星运行轨道受到干扰，这又说明了什么？
假设在六千五百万年前，地球俘获了月球，使得地球发生了偏移，阳光不能均匀的照耀大地，从而使地球气候环境发生变化，从而使长着茂密森林的北极将被厚厚的冰层所覆盖，地球上有春、夏、秋、冬四季交替。寒冷的天气把已经长有羽毛的这只恐龙更完善成一只鸟了！寒冷的天气会使已长有羽毛的恐龙长有更多的羽毛来抵御寒冷，寒冷的天气使食物缺乏，为了觅食，要扩大觅食面积，恐龙要飞的更远去觅食。寒冷的天气造成大迁徙！使飞翔得到加强与完善！只有月球才能使地球全球气候发生变化！
科学家有一些发现证明了恐龙生活时和恐龙消失后的一些变化：
一：恐龙时期的共同存在的动物如蚊子和蜻蜓比现在的蚊子和蜻蜓的体格要大？这是为什么？
二：恐龙时期的植物比现在的植物的“个子”要高？
三：恐龙时期的植物花的花瓣要比现在的花的花瓣数目要少？
这些都说明了什么？ 根据达尔文定理：环境在改变，生物为了适应环境的改变而在改变！气候发生了变化！而且是越变越恶劣！越变越多样！越变越复杂！为了适应环境的变化，生物也在改变！但有的恐龙是被环境无情的淘汰了！
恐龙如果在6500万年前灭绝了？从逻辑上也说不过去呀？！！
假设现在有1亿个种类的生物，那么在6500万年前就应该有1亿零1个种类的生物！（加上灭绝的恐龙）就是说远古时期生物的种类比现在存在的生物种类还有丰富？？这样也违背了达尔文的原理吧！！！！
