The extinction of dinosaurs The mystery of dinosaur extinction More than 200,000,000 years ago in the Mesozoic, a large number of reptiles living on land, it is also known as the Mesozoic ＂era of reptiles,＂ the earth was the first to occupy a wide range of vertebrates. At that time the Earth's climate was warmer, all over the dense forests, reptiles have enough food, graally prospered, more and more species. They continued to differentiate into a variety of different types of reptiles, some of today has bee a turtle, and some turned into the type of crocodile, and some turned into today's snakes and lizards, which are a class of Around the world and evolved into today's mammals. All is the dinosaur reptiles in the largest class of physical, very suitable for living in the marshes and shallow lake, when warm, humid air, food is also very easy to find. Therefore, dinosaurs ruled the earth for several million years of time, but I do not know why, in their 6500 years ago a very short period of time of the extinction of a sudden, people see only the left by that time a large number of dinosaur fossils. With regard to the reasons for the extinction of dinosaurs, it is still being studied. For a long time, the most authoritative view, and the extinction of the dinosaurs 6500 years ago about a large meteorite. According to the study, there was a 7-10 km in diameter asteroid will fall on the earth's surface, causing a large explosion, such as throwing a lot of st in the atmosphere to form the Zhetianbiri House of Sand and Fog, led to the suspension of plant photosynthesis , And therefore the extinction of the dinosaurs.

To Pull up the Seedlings to Help Them Grow Once upon a time, an old farmer planted a plot of rice. Everyday he went to the field to watch the seedlings grow. He saw the young shoots break through the soil and grow taller each day. But still, he thought they were growing too slowly. He got impatient with the young plants. ＂How could the plants grow faster?＂ He tossed in bed ring the night and could not sleep. Suddenly he hit upon an idea. He had an idea not wait for daybreak. He jumped out of the bed and dashed to the field. By the moonlight, he began working on the rice seedlings. One by one, he pulled up the young plants by half an inch. When he finished pulling, it was already morning. Straightening his back, he said to himself, ＂What a wonderful idea! Look, how much taller the plants have grown one night!＂ With great satisfaction, he went back home. He told his son what he had done in a triumphant tone. His son was shocked. Now the sun had risen. The young man was heart-broken to see all the pulled-up young plants dying. People now use ＂ Ba Miao Zhu Zhang＂ to describe the behavior of those who are too eager to get something done only to make it worse. The idiom is a bit like the English proverb ＂Haste makes waste＂ ------to spoil things by excessive enthusia *** . 拨苗助长 从前，有个农夫，种了稻苗后，便希望能早早收成。
每天他到稻田时，发觉那些稻 苗长得非常慢。
他等得不耐烦，心想：“怎么样才能使稻苗长得高，长很快呢？ 想了又想，他终了想到一个“最佳方法”，就是将稻苗拨高几分。
经过一番辛劳后，他满意地扛锄头回家休息。
心想：明天稻苗长得一定更高了。
隔天早晨.一早起身，他迫不及待地起去稻田看他的“成果”。
哪知，他跑到稻田时，却看到所有的稻苗都枯萎了。

恐龙的作文【50】字
所有恐龙已经灭绝，但是恐龙的后代——鸟类还是存活下来了，并繁衍至今。
恐龙（英文：dinosaur）是生活在距今大约2亿3 恐龙500万年至6596万年前的并且能以后肢支撑身体直立行走的一类陆生动物，是群中生代的多样化优势脊椎动物，大多数属于陆生（栖息在陆地上）的爬行动物，但能直立行走，支配全球陆地生态系统超过一亿六千万年之久。
恐龙是生活在距今大约2亿3500万年至6500万年前的、能以后肢支撑身体直立行走的的一类动物，支配全球陆地生态系统超过1亿6千万年之久。
大部分恐龙已经灭绝，但是恐龙的后代——鸟类存活下来，并繁衍至今。
另外在口语中，恐龙指丑女。
“恐龙”一词在字典中有两个意思：一类生活在几亿年以前的古动物，现已灭绝；（网络用语）当代相貌不好的女性。
从早侏罗纪到晚白垩纪，恐龙家族适应环境因而发展迅速，使得恐龙向着多样性方向发展，恐龙的种群数目增加，使恐龙这一类具有优势，恐龙由此得以支配地球陆地生态系统。
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，恐龙有温驯的素食者（吃植物的恐龙）和凶暴的肉食者（吃动物的恐龙），还有荤素都吃的杂食性恐龙.最古老的爬行类化石可追溯至古生代之“宾夕法尼亚纪”（约3亿2000万年前─2亿8000万年前）。
追本溯源，当系由两栖类演化而来。
两栖类的卵需在水中才能开始发育。
爬行类演化出卵壳，可阻止卵中水分的散发。
此一重大改革，使爬行类可以离开水生活。
从2亿4500万年前到6500万年前的中生代，爬行类成了地球生态的支配者，故中生代又被称为爬行类时代。
大型爬行类恐龙即出现于中生代早期。
植食性的迷惑龙，是体形与体重最大的陆栖动物。
棘龙是迄今为止陆地上最大的食肉动物。
另有生活在海中的鱼龙与蛇颈龙及生活于空中的翼龙等共同构成了一个复杂而完善的生态体系。
爬行类在地球上繁荣了约1亿8千万年左右。
这个时代的动物中，最为大家所熟知的就是恐龙。
人们一提到恐龙，眼前就会浮现出一只巨大而凶暴的动物，其实恐龙中亦有小巧且温驯的种类。
恐龙属脊椎动物爬行类，曾生存在中生代的陆地上的沼泽及灌木丛里，后肢比前肢长且有尾。
其中有许多种好食肉，许多种好食草。
其中发展较缓慢的种类，类似最古之鳄及喙头类，发展较完善的种类与鸟类相似。
北京时间10月30日消息，长久以来，古生物学家一直无法确定恐龙是否也像鸟类或者角马等动物一样进行迁徙。
由于可能面临异龙（霸王龙的远亲）带来的威胁，巨型食草恐龙在草原上迁徙并不是一个非常牵强的想法。
现在，美国科罗拉多州大学的研究人员第一次证明，恐龙也会在生存环境恶化时迁徙。
研究人员利用牙齿化石中的氧第一次证明，恐龙在泛滥平原之间迁徙。
在1862年发现的始祖鸟化石，与美颌龙化石极其相似，差别在于始祖鸟化石有明显的羽毛痕迹（美颌龙虽然也有羽毛，但它们很原始），事实上有相当一部分食肉恐龙具有原始羽毛，这显示恐龙与鸟类可能是近亲。
自从1970年以来，许多研究报告指出现代鸟类极可能是兽脚亚目恐龙的直系后代。
现在，大部分科学家视鸟类为唯一幸存发展至今的恐龙，而少数科学家甚至认为它们在生物学中应该分类于同一纲（即现未建成的恐龙纲）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初龙类演化支，该演化支首次出现于晚二叠纪，并在中三叠纪成为优势动物群。
从发现恐龙到20世纪前60年，由于对恐龙了解不足，科学家与大众媒体都视恐龙为行动慵懒、缓慢的冷血动物。
但是自从20世纪70年代开始的恐龙文艺复兴，提出恐龙也许是群活跃的温血动物，并可能有社会行为的观点。
近期发现的众多恐龙与鸟类之间关系的证据，支持了恐龙是温血动物的观点。
但事实究竟如何，还需进一步的考证。
实际上，人类发现恐龙化石的历史由来已久。
早在发现禽龙之前，欧洲人就已经知道地下埋藏有许多奇形怪状的巨大骨骼化石。
直到发现了禽龙并与鬣蜥进行了对比，科学界才初步确定这是一群类似于蜥蜴的早已灭绝的爬行动物。
1842年，英国古生学家查理德·欧文创建“dinosaur”这一名词。
英文的dinosaur来自希腊文deinos（恐怖的）Saurosc（蜥蜴或爬行动物）。
对于当时的欧文来说，这“恐怖的蜥蜴”或“恐怖的爬行动物”是指大的灭绝的爬行动物（实则不是）。
实际上，那个时候发现的恐龙并不多。
自从1989年南极洲发现恐龙后，全世界七大洲都已有了恐龙的遗迹。
目前世界上被描述的恐龙至少有650至700多种（生物学上的物种）。
后来，中国、日本等国的学者把它译为恐龙，原因是这些国家一向有关于龙的传说，认为龙是鳞虫之长，如蛇等就素有小龙的别称。
恐龙在地球上生存了近1亿7千万年的时光，在这么长的时间里，的环境也发生了许多变化。
原本连成一整片的盘古大陆逐渐漂移，分裂成为现在我们熟知的形态。
这些地球板块漂移到全球各处后，由于光照不再均匀，热量的传导也被海洋阻断，气候环境也跟着发生了改变。
在恐龙时代早期，蕨类植物构成...
小恐龙到动物园英文作文
今天，我和爸爸、爷爷、弟弟一起去看精彩的恐龙展。
恐龙展设在儿童公园里，一进儿童公园的大门就看到一张大海报，上面写着“重返侏罗纪”，再往里走会看到一只身材高大的机器蜀龙，再往前走就到了恐龙展的入口处。
进入恐龙展区就看见活灵活现的恐龙机器人，它们的身高和书上描写的恐龙一样大小，好像我们直接进入了侏罗纪公园，耳边不时传来恐龙的恐怖叫声。
那些恐龙的种类有恐龙世界的“高个子”梁龙、背上长着三角形骨板的剑龙、拥有恐怖爪子的恐爪龙……，走着走着我们来到了肉食性恐龙中最凶猛的暴龙展览处，那只暴龙和《侏罗纪公园》这部电影里面的暴龙一模一样，好像它马上就要把我们给吃了。
这些恐龙的皮是用橡胶做的，恐龙旁边放着一个发音盒，恐龙的叫声就是从这个发音盒发出来的。
那些恐龙叫声声音怪异，有时会突然叫得特响，你会被这叫声吓一大跳；有些恐龙的头会藏在树丛间，等你不经意发现时，会吓得你魂飞魄散。
庞大的恐龙家族为什们会消失了呢？据科学家推测：由于地震使大陆分离，各地气候大变，恐龙无法适应，最后灭绝了。
这次恐龙展让我了解了更多恐龙的知识，我希望能进一步发现恐龙的奥秘。

㈡ 介绍恐龙 英语作文
A beautifully preserved fossil from southern Germany raises questions about how feathers evolved from dinosaurs to birds, two paleontologists argue in a study published Thursday.
The 150 million-year-old fossil is a juvenile carnivorous dinosaur about 2 1/2 feet long that scientists named Juravenator, for the Jura mountains where it was found.
It would have looked similar in life to the fleet-footed predators that menaced a young girl on the beach ring the opening scene of "The Lost World," the second Jurassic Park movie.
The fossil's exceptionally well-preserved bone structure clearly puts it among feathered kin on the dinosaur family tree. Because all of its close relatives are feathered, paleontologists would expect Juravenator to follow suit.
But a small patch of skin on the creature's tail shows no sign of feathers. And the skin also doesn't have the follicles that are typical of feathered dinosaurs, said Luis Chiappe, director of the Dinosaur Institute at the Natural History Museum of Los Angeles County. He and Ursula B. Gohlich of the University of Munich describe the fossil in Thursday's issue of the journal Nature.
"It has a typical scaly dinosaurian skin," Chiappe said.
The paleontologists believe Juravenator's closest known relative may have been a fully feathered dinosaur from China, Sinosauropterix.
There are a number of possible explanations for Juravenator's nakedness. Feathers could have been lost on the evolutionary line leading to Juravenator after arising in an ancestor to both it and its feathered relatives. Or feathers could have evolved more than once in dinosaurs, cropping up in sister species at different times and places. It is also possible that this particular fossil of Juravenator, which appears to be a juvenile, only grew feathers as an alt or lost its feathers for part of the year.
But there is another possibility as well, said Mark Norell, curator of paleontology at the American Museum of Natural History: It is entirely possible that Juravenator did have feathers, but they simply failed to fossilize.
"Feathers are really just difficult things to preserve," Norell said.
To support his hypothesis he pointed out that several fossils of the oldest known bird, archaeopteryx, lack feathers.
Whether or not the new specimen raises interesting questions about how feathers — and thus birds — evolved, most experts do not see it as a challenge to the widely accepted view that modern birds are descended from dinosaurs
㈢ 用英语描写恐龙的外貎小作文,带翻译
Most dinosaurs have some common features, but because of the presence of other major dragon classes, or do not exist in the early dinosaurs, so they are not listed as a dinosaur's common. Dinosaurs have an upright gait, similar to most modern mammals, while most other reptiles are the legs to extend the two sides of the gait. The dinosaur's hip fossa is toward both sides, and the fourth of the femur is in the inner side of the femur. The two are in agreement to proce an upright gait.

Dinosaurs are a diverse group of animals that were the dominant terrestrial vertebrates for over 160 million years, from the late Triassic period (about 230 million years ago) until the end of the Cretaceous (about 65 million years ago). The extinction of most dinosaur species occurred ring the Cretaceous–Tertiary extinction event. The fossil record indicates that birds evolved from theropod dinosaurs ring the Jurassic period. Some of them survived the Cretaceous–Tertiary extinction event, including the ancestors of all modern birds. Consequently, in modern classification systems, birds are considered a type of dinosaur — the only group of which that has survived to the present day.。
