侏羅紀(jì)搏擊俱樂部 第171期:重塑恐龍的最后時刻

The impact of this asteroid was unparalleled.

這次小行星的撞擊威力空前。

The power it released was greater than the combined force of man's entire nuclear arsenal.

Recreating the sequence of events that happened immediately following something as cataclysmic as this event can be difficult because so much of the evidence was obliterated at the moment of impact.

要重塑如此規(guī)模的災(zāi)難事件發(fā)生后的事件順序非常困難，因為很多證據(jù)在撞擊的時候就被摧毀了。

But by relying on worldwide evidence, we can formulate a pretty accurate idea of what occurred.

不過根據(jù)世界范圍的證據(jù)，我們可以構(gòu)建比較準(zhǔn)確的情況。

Gathering information from scientists around the world and looking closely at the evidence, the following scenario recreates the final moments of the dinosaurs.

科學(xué)家們在世界各地收集信息并仔細(xì)檢驗這些證據(jù)，下面的場景重塑了恐龍的最后時刻。

After colliding with another asteroid millions of miles from earth, fragments of the Baptistina asteroid were thrown into space.

Hunting together makes it easier to ambush and capture prey, and keeping their young nearby offers them protection from rivals.

群體狩獵使得伏擊和捕獲獵物更加容易，而且能把幼獸帶在身邊，不易受到競爭者的傷害。

They're the biggest land predators on earth, but even their might is no match for nature's fury.
