恐龙的英文译语怎么说

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关于清明节的知识 者，还有荤素都吃的杂食性恐龙。
