侏羅紀(jì)搏擊俱樂部 第102期:統(tǒng)治地球的掠食者

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

它們是精英，是統(tǒng)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.

它們中有霸王龍一樣的巨獸靠身強(qiáng)力壯和長(zhǎng)牙彎齒稱霸，也有小一些的迅猛龍以速度和狡黠見長(zhǎng)。

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

科學(xué)將拓展證據(jù)揭示這些恐龍是多么地迥然不同。

They were the Earth's largest animals.

它們?cè)堑厍蛏献畲蟮膭?dòng)物。

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

新的科技和現(xiàn)場(chǎng)證據(jù)如今幫助古生物學(xué)家們重現(xiàn)了它們生命中的最后時(shí)刻

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

史前地球，三億五千萬年前，我們今天熟悉的大陸還不存在。

There was one major land mass called Pangaea.

那時(shí)只有一片主要的陸塊叫做泛大陸。

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

在泛大陸上，如今的香港和紐約兩個(gè)城市只相隔3000英尺。

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

在侏羅紀(jì)末期，超級(jí)大陸泛大陸分崩離析。

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

構(gòu)成這片巨大陸地的獨(dú)立部分開始旋轉(zhuǎn)，開始時(shí)速度不一樣，之后方向也不一樣。

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

這導(dǎo)致這些陸塊間出現(xiàn)巨大裂縫，并且最終形成了我們今天看到的各個(gè)大陸。

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

隨著它們繼續(xù)分離，某些情況下的環(huán)境變化是災(zāi)難性的。

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

一億五千六百萬年前，正值侏羅紀(jì)時(shí)期，海洋在地球上覆蓋范圍為史上之最。

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

通過板塊構(gòu)造的力量，陸塊移位，海平面上升淹沒了大片區(qū)域。

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

現(xiàn)代的美國重要城市，休斯頓、新奧爾良、邁阿密，甚至是中西部，當(dāng)時(shí)都是幾百米深的水域。

The ocean extended all the way to central Utah.

海洋一直延伸到猶他州中部。

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們發(fā)現(xiàn)了第一種大型殺手，侏羅紀(jì)的恐怖魔星——異特龍。

The name Allosaurus means "other reptile".

異特龍的名字原意為“其它爬行動(dòng)物”。

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

它在一億五千六百萬年前到一億四千五百萬年前生活于晚侏羅紀(jì)時(shí)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.

在科羅拉多州、猶他州、懷俄明州和蒙大拿州都曾發(fā)現(xiàn)過其遺骸。在那時(shí)，異特龍的兇殘無可匹敵。
