Judy's theory was that this would have transformed the world's climate.
Judy的觀點是這將改變全球氣候
Different climate zones would have created new ecosystems and new ecosystems meant new life.
不同的氣候帶創造了新的生態系統，新的生態系統意味著新的生物
If Judy was right, this could have been the key to the dinosaurs transformation in the mid-Jurassic.
如果Judy是對的，那就意味著這就是開啟中侏羅世恐龍盛世的鑰匙
Seems likely that some kind of major climate change,
非常有可能的是，這類氣候巨變
or some major climate system has to have some sort of effect on the evolution of life including that of the dinosaurs,
或者說是氣候系統巨變影響到了生物的進化，包括恐龍在內
so it's really interesting to try to figure out whether those animals evolved in response to any kind of climate change.
所以找出動物進化是否反映了氣候變化是一件很有趣的事
So was climate change the evolutionary master key that transformed the dinosaurs?
那么，氣候是否改變了進化密鑰，從而使恐龍發生劇變呢
Until Argentina, there was no way of knowing.
直到阿根廷這次發現之前，人們都無從得知
This is where the richness of the Argentinean site came into its own.
這也使得阿根廷這片富饒的化石場成了世人關注的焦點
Look at that, that's really extraordinary.
瞧這兒，它非常特別
We have like there a rib, a rib there, a rib there, a rib there, a rib there...
看上去像是肋骨、肋骨、肋骨、肋骨、肋骨……
Because they had found such a complete ecosystem, they could search for climatic clues amongst the fossils
由于他們發現了整個生態系統，他們便能從化石中找出氣候線索
and since the site covered millions of years, they'd be able to see how the climate had changed over time
這個地方已在地下埋藏了億萬年，使他們得以了解氣候如何隨著時間發生變化
and the first clues came not from the dinosaurs, but from the lake where the fossil fishes had been found.
第一條線索并非來自恐龍，而是來自發現魚類化石的湖泊。
