Jurassic Period 侏罗纪

Jurassic Period is a geologic period that extends from 199.6 million to 145.5 million years ago; from the end of the Triassic to the beginning of the Cretaceous. The Jurassic constitutes the middle period of the Mesozoic Era, also known as the Age of Reptiles. 侏罗纪是一个地质年代，约1亿9960万年前到1亿4550万年前，界于三叠纪和白垩纪之间。侏罗纪是中生代，也称爬动作物期间，的第二个纪。

Named for the Jura Mountains on the border between France and Switzerland, where rocks of this age were first studied, the Jurassic has become a household word with the success of the movie Jurassic Park. 侏罗纪的称呼取自于法国、瑞士边界的侏罗山，东说念主们初次在哪里发现该年代的岩石。电影《侏罗纪公园》的得手使得侏罗纪成为尽人皆知的词汇。

During the Jurassic Period, the supercontinent Pangaea split apart. The northern half, known as Laurentia, was splitting into landmasses that would eventually form North America and Eurasia. 在侏罗纪，超等陆块盘古大陆启动永诀，其北部的劳伦西亚大陆永诀成多个大陆块，最终酿成北好意思洲和欧亚大陆。

The southern half, Gondwana, was drifting into an eastern segment that would form Antarctica, Madagascar, India and Australia, and a western portion that would form Africa and South America. 南部的冈瓦纳大陆不时漂移，其东段最终将酿成南极洲、马达加斯加岛、印度和澳大利亚，而西部则酿成非洲和南好意思洲。

This rifting, along with generally warmer global temperatures, allowed for diversification and dominance of the reptiles known as dinosaurs. 大陆的永诀，以及举座较暖的民众气温，为爬动作物，即恐龙，的衍生变化和总揽提供了绝佳环境。
