Fossil remains of dinosaurs have been found in rock strata of every continent, indicating that they differed widely in structure, habitat, and diet. Their brain sizes varied, with some predators having brain-to-body ratios equivalent to those of some modern birds and animals. Many species built nests. Many theories regarding dinosaurs and their behavior are hotly debated by the experts. These include the debate over the grouping of birds with dinosaurs, the question of whether nonavian dinosaurs were cold-blooded (ectothermic) or warm-blooded (endothermic), the question of whether dinosaurs protected and nurtured their young in the nest after hatching or whether the young were mobile and self-sufficient at birth, and the reason for the disappearance of nonavian dinosaurs.

No complete fossil dinosaur has ever been discovered. Inferences must be made from fragments or pieces that have been compressed and distorted. Information about the diet has been gleaned from stomach contents and coprolites (fossilized dinosaur feces) and by comparing the teeth to those of living animals, for example, relating the large grinding teeth of hadrosaurs to those of living herbivores. Fossilized dinosaur footprints, such as the trackways found at Davenport Ranch in Texas, have been interpreted as evidence that dinosaurs traveled in herds. What is known about dinosaurs is that, far from being evolutionary failures, they dominated their habitats for most of their 160 million years of existence (the human species Homo sapiens has existed for approximately 150,000-200,000 years).

Although all dinosaurs were originally classified in a single order, it was later discovered that the group contained two distinct types distinguished by structural differences. The pelvis in the saurischian (lizard-hipped) dinosaurs resembles that of still-extant reptiles, but in the ornithischian (bird-hipped) dinosaurs the pubic bone of the pelvis has forward and backward extensions that resemble those found in birds. It was later determined, however, that the backward-tilting hips of ornithischian dinosaurs and birds were the result of convergent evolution and not inheritance. Many other shared characteristics have been noted between birds and saurischians, and it is now believed by many paleontologists that modern birds are in fact extant dinosaurs of the saurischian order.

The jaws and teeth of the two dinosaur orders also differ. The saurischian order, which includes both herbivores and carnivores, has teeth around the entire jaw or confined to the front of the mouth. Ornithischians have “cheek teeth” along the sides of the jaw, but never in the front; the bones at the front of the mouth sometimes developed into the horny beaks typical of modern turtles. All known ornithischians were herbivores.

Dinosaurs are further classified into some common groupings. In the saurischian dinosaurs, some were theropods [Gr., = beast feet], a group sharing hind feet with only three functional toes (e.g., the carnivorous bipeds Tyrannosaurus , Velociraptor , Deinonychus , and possibly the living birds); others were sauropods [Gr., = lizard feet] with small heads and long necks (e.g., the herbivorous quadrupeds Apatosaurus [Brontosaurus] and Diplodocus ). Among the ornithischians, there were ornithopods (bird-footed dinosaurs), such as Iguanodon ; thyreophorans (armored dinosaurs), such as Stegosaurus and Ankylosaurus ; and ceratopsians (horned dinosaurs), such as Triceratops . The total number of dinosaur genera that existed is unknown; new species are discovered every year, but some species, on further examination, are found to be redundant with earlier finds. One estimate of the possible number of distinct genera exceeds 1,800.

Similarities of dinosaurs found on what are now different continents have given scientists clues to the breakup of the supercontinent Pangaea, which began about 170 million years ago. For example, the discovery of a 130-million-year-old African dinosaur similar to the North American Allosaurus suggests that the African plate was connected to the northern continents (Laurasia) longer than had been believed previously.
Dinosaurs were reptiles and most dinosaurs hatched from eggs. Amazingly blue whales are bigger than any dinosaur found so far. The largest dinosaurs were over 100 feet long and up to 50 feet tall. The smallest dinosaurs, were about the size of a chicken.

No one knows exactly what noises dinosaurs made, what color they were or even when they lived. But scientist do have theories on these topics and you can find some of this information in our links.

Most dinosaurs were plant-eaters (herbivores) about 65% of them. Some dinosaurs were meat-eaters (carnivores). Dinosaurs had many different distinguishing features that you can read more about when reading facts on each dinosaur.

No one really knows exactly how many dinosaur species exist. The estimates vary from between 250 to over 1300 species.

The term dinosaur (terrible lizard) was coined by the English anatomist Sir Richard Owen in 1842.

No one knows how the dinosaurs became extinct or even if they are extinct, but there are many interesting theories on the topic and you can read more about them from our links page.

恐龙是出现在中生代时期（三叠纪，侏罗纪和白垩纪）的一类爬行动物的统称，矫健的四肢、长长的尾巴和庞大的身躯是大多数恐龙的写照。它们主要栖息于湖岸平原（或海岸平原）上的森林地或开阔地带。
恐龙种类多，体形和习性相差也大，其中最大的易碎双腔龙可能超过50米，而最小的蜂鸟可能还不到10厘米。就食性来说，有温顺的草食者和凶暴的肉食者，还有荤素都吃的杂食性恐龙。
恐龙生活的中生代，大气中的二氧化碳的含量较高，说明恐龙很适应于高二氧化碳浓度的大气环境。也许只有在那种大气环境中，它们才能很好的生活。
当时，尽管哺乳动物也已经出现，但是它们始终没有得到大发展，也许这正是由于大气成分以及其它环境对它们并不十分有利，因此它们在中生代一直处于弱小的地位，发展缓慢。
随着时间推移，到了白垩纪之末，大气环境发生了巨大的变化，二氧化碳的含量降低，氧气的含量增加，这种对恐龙不利的环境可能体现在两个方面，一是恐龙的身体发生了不适，在新的环境下，很容易得病，而且疾病会像瘟疫一样蔓延。
二是新的大气环境更适于哺乳动物的生存，哺乳动物成为更先进、适应性更强的竞争者。在这两种因素的作用下，恐龙最终灭绝了。

恐龙的生活习性：
1、觅食
草食性恐龙能够吃到的植物受限于它们的身高，所以有些小型草食性恐龙为了吃到高处的植物叶子，会用后肢站立。肉食性恐龙以草食性恐龙和其他动物为食。各种恐龙不同的觅食方式也会在它们的牙齿上体现出来。
2、斗争
锐利的牙齿和爪子是肉食类恐龙猎食的武器。暴龙类恐龙会寻找落单的草食性恐龙，因此常常单独行动。而有些恐龙则会群体行动，锁定猎物后蜂拥而上，并用第二根趾头的脚爪割开猎物的腹部。
草食性恐龙一般会有一些特殊的“装备”来对付肉食性恐龙的攻击，这些装备有时是坚韧的皮甲、骨棒或骨钉，有时是有力的尾巴。如棒槌龙等。大型草食性恐龙会集体行动，一旦受到威胁，就会集体坚守阵地并反击。

Death of dinosaurs
In the Mesozoic period which wa about 70 million years ago to 20 million years ago was a flourishing time for creeping animals. They were the emperors of the earth., reigning the sea, the land and the sky. We call this kind of animal " dinosaur".
There are many types of dinosaurs. We can divide them into two kinds, bird dinosaur and lizard dinosaur according to their pelvises, and divide them into meat-eating kinds and grazer kinds according to the food they ate. There were big-sized dinosaurs and small-sized. It is presumed that the heaviest dinosaur was about 80 meters in length, 40~50 tons in weight, while the slim crocodile dinosaur was only about 60cm in length, 3kg in weight, almost like hens. Dinosaurs had different living spaces, some flying in the sky like bats, some swimming in the water like dolphins, some living on the land upright.. Such a big dinosaur family suddenly disappeared 65 million years ago. Some sea creeping animals, flying creeping animals, some fishes and other living animals, etc., accompanied those dinosaurs to death. Their death still is a big mystery to the scientists.

There is an acceptable saying that groups of dead dinosaurs have some relationship with the move of the earth. During the Mesozoic period, many hills took the place of swamps. The climate also changed, cold seasons and warm seasons began to appear by turns. So the cold-blooded dinosaurs could not adapt themselves to such cold weather, their body temperature began to fall with the decline of temperature, then they died. On the other hand, their breath organ could only stand wet and hot air, not dry and hot air. Due to the changes of the climate, the flourishing plants, such as some fern began to disappear, everything withered, and dinosaurs began to face the disaster of hunger. Since dinosaurs' body structure had defined itself after a long evolution, they could not adapt themselves to such a sudden change. Death was the only way for them to go. Only some dormient snakes, dinosaurs of lizard kind, some small mammals with furs on their body which could hide themselves in caves avoiding coldness and some birds were left alive. There was a theory similar to the above theory to say that the death of dinosaurs was directly caused by the continental shift. When dinosaurs appeared on the old mainland, there might have been a dinosaurs' heaven. Until Jurassic, the old mainland came to crack into small pieces and began to float in all directions. Due to the move of the land, climate went worse, temperature went down, huge changes happened on the dinosaurs' environment by the end of the Cretaceous period. They didn't have any cold-resistant supplies or any physical energy to avoid such coldness, so all of them went to death.
There is also an academic opinion in the science world, they thought that the death of dinosaurs was due to the impacts of meteorites. This was called meteorites sciences. Some scientists presumed that some small planet fell into the sea, speeding at 40 kilometers / second from the sky, forming a deep hole within 4 seconds, with high-temperature smoke poles reaching to a height of 40 kilometers and surfs 5 kilometers high and its gasified dust attacking the earth. At this time, snow on the icy earth began to melt away, the plants began to die, dinosaurs were covered under the earth. Of course, this meteorite might have fallen on the mainland, that would have aroused more serious destruction. Until now, there is no clear evidence which could prove such a presumption. If such a thing happened on the earth, we should find a big meteorite hole on the surface of the earth. Some scientists presumed that such a meteorites' fall on the earth was not in one piece, but in thousands like heavy rain. Though they were small, the power of every meteorite was more than several A-bombs. Falling on the land together would result in entire destroy.
Some astronomers forwarded a theory of a supernova explosion. These supernova are some shining star bodies which could perish suddenly. Due to the temperature and the density of the star nucleurs overstepping the ambit of the star body itself, a burst resulted, emitting strong visible light, cosmic rays and X-rays. This was called a supernova explosion. The X-rays emanated from the burst would carry high energy, the same energy as 10 suns, raising the earth's surface temperature. Big typhoons and strong storms appeared on the surface of the earth, the high-temperature air formed into icy clouds and hid the sun. Since the dinosaurs had adapted themselves to warm weather, such a sudden cold weather brought them to death.
Some biologists considered that dinosaurs died out because of food poisoning. The food dinosaurs ate, such as fern, cycad, gingko, pines, etc. are plants with no flowers, they would do no harm to dinosaurs. But some plants with flowers appeared afterwards, their flowers contained much alkaloid with much poisons. Dinosaurs ate many such plants which resulted in their death.
Many dinosaur fossils were discovered in the ZiGong area in China, which was called "Dinosaurs' home", many foreigners admired the Chinese and called them "rich men with dinosaurs". After scientists analyzed these dinosaur fossils using spore powder, sediment, spectral analysis, etc., they discovered that the arsenic in these fossils was over 100PPM., so they thought that these poisonous plants caused the death of dinosaurs.
Except this, scientists also made all kinds of presumptions on the dinosaurs' death.. Some people thought that mammals were shrewd with agile action at that time, so they often robbed dinosaurs' food, which made ponderous and stupid dinosaurs hungry to death. They also stole dinosaurs' eggs to eat so that dinosaurs lost their offspring.
Some people presumed that volcanoes broke out frequently at that time. Eruption polluted air and hid the sun, so the whole environment changed suddenly. Devoid of oxygen and rain, swamps and mountains dried up, so plants went to death. In such a bad situation, dinosaurs had to disappear from this world.
A French scientist named Daditeur forwarded his unique idea on the extinction of dinosaurs. He thinks that dinosaur broke wind a lot and released a lot of methane into the air. Because they were in such a great number, the wind they released destroyed the ozonosphere and formed a destructive climate.
There was an abroad research team having a 20 years' study on dinosaurs and drew a conclusion that visitors from another planet destroyed the dinosaurs. An ancient anthropologist from the former Soviet Union said: "Visitors from another planet began to hunt dinosaurs 60 million years ago, and destroyed this animal within thousands of years." Dinosaurs has some intimate relationship with birds. To these visitors, dinosaurs were just like delicious chickens. They hunted tons of dinosaurs meat every year. Four years ago, a dinosaurs tomb was discovered in Arctic Pole, which proved his viewpoint. In that tomb, thousands of dinosaurs were discovered, on some of their brain bones laser cut marks had remained. There is some hint that visitors from another planet brought dinosaurs to their planet as their domestic animals, maybe they had sensed that dinosaurs would disappear from the earth some day.
Other ancient anthropologists agreed with his scientific report. An English expert said: "We have some actions in common with those visitors from another planet, such as overhunting, leading animals to extinction. So his idea sounds reasonable.". Some ancient anthropologists decided to look for a slaughterhouse in Arctic Island.
Which is the most reasonable explanation or the truth? We believe this mystery will surely be uncovered some day.
