They were the elite, the predators that ruled the earth.

它们是精英,是统治地球的掠食者。

They ranged from the giant T-Rex, who relied on size and long curved teeth, to the smaller Raptors, who used speed and cunning.

它们中有霸王龙一样的巨兽靠身强力壮和长牙弯齿称霸,也有小一些的迅猛龙以速度和狡黠见长。

Science expends the evidence to unravel how widely different these dinosaurs were.

科学将拓展证据揭示这些恐龙是多么地迥然不同。

They were the Earth's largest animals.

它们曾是地球上最大的动物。

New technology and forensic evidence helps paleontologists bring to life some of their final moments.

新的科技和现场证据如今帮助古生物学家们重现了它们生命中的最后时刻

Prehistoric earth, 350 million years ago, the continents as we know them didn't exist.

史前地球,三亿五千万年前,我们今天熟悉的大陆还不存在。

There was one major land mass called Pangaea.

那时只有一片主要的陆块叫做泛大陆。

On Pangaea, the cities of Hong Kong and New York would have been separated by only 3,000 miles.

在泛大陆上,如今的香港和纽约两个城市只相隔3000英尺。

At the end of Jurassic, the super-continent Pangaea was disintegrated.

在侏罗纪末期,超级大陆泛大陆分崩离析。

The individual components that made up this huge land mass were beginning to rotate, first, at different rates, and then at different directions.

构成这片巨大陆地的独立部分开始旋转,开始时速度不一样,之后方向也不一样。

This caused huge rifts between these land masses and ultimately created the continents we see today.

这导致这些陆块间出现巨大裂缝,并且最终形成了我们今天看到的各个大陆。

As they continued to break apart, the environmental changes in some cases are catastrophic.

随着它们继续分离,某些情况下的环境变化是灾难性的。

156 million years ago, during the Jurassic period, the oceans were more widespread than at any time on earth.

一亿五千六百万年前,正值侏罗纪时期,海洋在地球上覆盖范围为史上之最。

Through the forces of plate tectonics, the land masses shifted and sea level rose flooding large areas.

通过板块构造的力量,陆块移位,海平面上升淹没了大片区域。

Where major American cities are now, Huston, New Orleans, Miami, even the midwest, were waters hundreds of meters deep.

现代的美国重要城市,休斯顿、新奥尔良、迈阿密,甚至是中西部,当时都是几百米深的水域。

The ocean extended all the way to central Utah.

海洋一直延伸到犹他州中部。

It was in that world that the first big killer could be found, the terror of the Jurassic - Allosaurus.

就是在那片世界里人们发现了第一种大型杀手,侏罗纪的恐怖魔星——异特龙。

The name Allosaurus means "other reptile".

异特龙的名字原意为“其它爬行动物”。

It lived in western North America during the late Jurassic period from 156 to about 145 million years ago.

它在一亿五千六百万年前到一亿四千五百万年前生活于晚侏罗纪时期的北美西部。

Its remains have been found in Colorado, Utah, Wyoming and Montana.And at its time, there was nothing as bad as Allosaurus.

在科罗拉多州、犹他州、怀俄明州和蒙大拿州都曾发现过其遗骸。在那时,异特龙的凶残无可匹敌。
