用英文介绍恐龙+翻译 简短一些

恐龙的英文介绍是：

1、英文介绍：

Dinosaur refers to the recent common ancestor and all descendants of Triceratops, modern birds and Lianglong. For the convenience of research, dinosaurs can be divided into birds and non birds dinosaurs. 

Among them, non bird dinosaurs only lived in the Mesozoic and became extinct 65 million years ago. This entry mainly introduces non bird dinosaurs. 

Vigorous limbs, long tail and huge body are the portrayal of some non bird dinosaurs. They mainly inhabit in the forest or open areas of the lake shore plain.

2、中文翻译：

恐龙，是指三角龙，现代鸟类和梁龙最近的共同祖先及其所有后代。为方便研究，恐龙可分为鸟类和非鸟恐龙。其中，非鸟恐龙只生活在中生代，已于6500万年前全部灭绝。

而本词条主要介绍非鸟恐龙。矫健的四肢、长长的尾巴和庞大的身躯是部分非鸟恐龙的写照。它们主要栖息于湖岸平原的森林地或开阔地带。

外形特征：

大部分的恐龙要比大型蜥脚类恐龙还小得多。现有的证据表明，恐龙的平均大小在三叠纪、早侏罗纪、晚侏罗纪和白垩纪都不断变化。

大部分兽脚类恐龙的体重在100到1000公斤之间，而全新世的掠食性肉食动物则多半在10到100公斤之间。恐龙的体重估计值，大多介于1到10吨之间。伦敦国立自然历史博物馆的一个研究指出恐龙的体重平均值约在100公斤左右，而新生代的哺乳类体重平均值多在2到5公斤之间。

以上内容参考 百度百科—恐龙

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。恐龙”一词在字典中意思：一类生活在几亿年以前的古动物，现已灭绝.

Dinosaurs lived about 200 million in 3500 million years ago to 6500 million years ago, can support the body upright limb of a class of animals, the control of global terrestrial ecosystems over 100 million 6 million years. Most dinosaurs have become extinct, but the descendants of dinosaurs - birds, survive and reproduce so far. Dinosaur "in the dictionary has two meanings: one living in hundreds of millions of years ago the ancient animal, now extinct.

The Dinosauria
Dinosaurs, one of the most successful groups of animals (in terms of longevity) that have ever lived, evolved into many diverse sizes and shapes, with many equally diverse modes of living. The term "Dinosauria" was invented by Sir Richard Owen in 1842 to describe these "fearfully great reptiles," specifically Megalosaurus, Iguanodon, and Hylaeosaurus, the only three dinosaurs known at the time. The creatures that we normally think of as dinosaurs lived during the Mesozoic Era, from late in the Triassic period (about 225 million years ago) until the end of the Cretaceous (about 65 million years ago). But we now know that they actually live on today as the birds.
