這些化石也許代表了

the most important leap forward in the history of lifeon our planet,

地球生物歷史上最重要的飛躍

but that doesn't mean they are easy to spot.

不過這并不意味著很容易就能發(fā)現(xiàn)他們。

This is a very old surface, you clean it off

這個表面非常古老首先清潔一下

and then push this putty onto the surface,

然后把這塊灰泥壓上去

you can actually see the impression.. Look at that.

您就能親眼看見.. 看那里

of a thing called Parvancorina.

帕文克尼亞蟲的印痕

You know, it looks like somebody's Signet ring.

看起來很象是圖章戒指

- It's like a trademark.- Exactly,yeah.

象某種商標(biāo)- 沒錯

And that is really all the fossils is.

這已經(jīng)就是化石的全部了

It's the impression of this soft-body creature

這是這種軟體動物全部的印痕

as it was preserved instantly on the sea floor about 560 million years ago.

正如同5億6千萬年前 他們初次保存在海底時一樣

This are nothing of the fossil that I am used to.

這和我所熟悉的那些化石完全不同

I mean,that...I would never,ever have spotted that.

我的意思..我絕對不可能注意到他們的

Parvancorina wouldn't attract much attention today,

帕文克尼亞蟲 如今不可能吸引太多的關(guān)注

but this animal had made a gigantic evolutionary leap.

但這種動物完成了 一次巨大的進(jìn)化飛躍

Unlike single celled microbes,

與單細(xì)胞微生物不同

this was a complex creature with a head, skin, and internal organs.

它擁有頭、皮膚、內(nèi)部器官 是一種復(fù)雜生物。
