恐龙的英语资料
The word "dinosaur" comes from the ancient Greek words "deinos" ("terrible") and "sauros" ("lizard"). Strictly speaking, dinosaurs refer to land dwelling creatures that dominated life on earth during the Mesozoic Era (225 million to 65 million years ago). They lived alongside with marine reptiles (such as ichthyosaurs, mosasaurs, plesiosaurs) and flying reptiles. As a group, dinosaurs existed for over 150 million years, occupying every type of environment and climate on Earth. They ranged in size from those as small as a chicken to others over 100 feet long and weighing nearly 100 tons. Dinosaurs did not achieve their great size or domination overnight - they evolved alongside reptiles and mammals, but managed to outcompete them. Were it not for the great Cretaceous extinction 65 million years ago, the mammals would not have evolved as they did, nor would human beings as we know them exist
恐龙简介
恐龙是出现于二亿四千五百万年前，并繁荣于六千五百万年前结束的中生代爬行动物。或为恐龙和与它同一时代的蛇颈龙、翼龙等的模糊总称。恐龙在在6500万年前白垩纪结束的时候突然全部消失，成为地球生物进化史上的一个谜，这个谜至今仍无人能解。地球过去的生物，均被记录在化石之中。中生代的地层中，即曾发现许多恐龙的化石。其中可以见到大量或呈现各式各样形状的骨骼。但是，在紧接着的新生代地层中，却完全看不到恐龙的化石。由此推知恐龙在中生代时一起灭绝了。
恐龙种类多，体形和习性相差也大。其中个子大的，可以有几十头大象加起来那么大；小的，却跟一只鸡差不多。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。

恐龙是出现于中生代多样化优势陆栖脊椎动物。“恐龙”一词是生物学家对英文Dinosauria即“恐怖的蜥蜴”的翻译，并不是中国传统文化中的“龙”。恐龙曾支配全球陆地生态系统超过1亿6千万年之久。恐龙最早出现在2亿3千万年前的三叠纪晚期，在大灭绝中脱颖而出，灭亡于约6千5百万年前的白垩纪晚期所发生的白垩纪末灭绝事件。在1861年发现的始祖鸟化石，与美颌龙化石极度相似，差别在于始祖鸟化石有着羽毛痕迹[1] ，这显示鸟类可能是恐龙的后代。
自从20世纪70年代以来，许多研究指出现代鸟类极可能是兽脚亚目K恐爪龙类恐龙的直系后代。大部分科学家视鸟类为唯一幸存发展至今的恐龙，而少数科学家甚至主张它们应该分类于同一纲之内。鳄鱼则是另一群恐龙的现代近亲，但两者关系较恐龙与鸟类远。恐龙、鸟类、鳄鱼都属于爬行动物的主龙类演化支，该演化支首次出现于二叠纪晚期，并在三叠纪中期成为优势水陆两栖动物群。恐龙（不包含鸟类）是群生存于陆地上的主龙类爬行动物，四肢直立于身体之下，而非往两旁撑开。[2] 许多史前爬行动物常被一般大众非正式地认定是恐龙，例如：翼手龙、鱼龙、蛇颈龙、沧龙、盘龙类（异齿龙与基龙）等，但从科学角度来看，这些都不是恐龙。
有科学家最新研究认为，0.66亿年前小行星碰撞地球时，正值恐龙生态系统较脆弱时期，遭遇小行星碰撞所致的环境巨变，恐龙在生活了1.6亿年后走向灭绝。

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.
