纪录片《恐龙灭绝真相》 第18期 岩石迅速形成的证据（在线收听）

The fact that we find these species in the rocks above the Chicxulub impact rocks

在希克苏鲁伯大碰撞上方岩层发现这些物种，

means that Chicxulub impact must predate the mass extinction by about three hundred thousand years

说明希克苏鲁伯大碰撞肯定比大灭绝提早了大约30万年，

and that just confirms what we already found.

这也证明了我们之前的发现。

Keller and Stinnesbeck thought they had won.

Keller和Stinnesbeck认为他们已大获全胜。

For them, the evidence proved beyond doubt that Chicxulub was far too old to have caused the extinction of the dinosaurs.

在他们看来，希克苏鲁伯大碰撞毫无疑问发生得太早了，不可能造成恐龙灭绝。

But that was just one way to look at it.

但这只不过是一家之辞。

When Jan Smit analysed the core, he saw something quite different.

当Jan Smit分析岩芯时，他发现了一些完全不同的东西。

He found evidence that the rock had been created quickly.

他找到了岩石迅速形成的证据。

Look here for instance, you see here ripple marks,

比如说看看这里，你能看见这些波状纹理，

there's another layer of ripple marks, there are lines in the rocks,

这是另一条波状纹理，它们排在岩石中，

they all bear evidence for strong currents which implies Tsunami events.

这些都是强大水流的证据，也就意味着海啸事件。
