During times of drought, animals are stressed to the limit.
在干旱時期，動物們的壓力已至極限。
Normal behavior is basically thrown out the window and it becomes a no holds bar fight for survival.
通常的行為都已不再適用，這已經變成了沒有限制的生存斗爭。
If Utahraptor and Gastonia happened to meet and I think they would have tended to avoid each other but if environmental factors such as extreme drought, food deprivation, that sort of things forced an unpleasant interaction, I would tend to think that, like all predators, Utahraptor would be forced to assess the health conditions of the Gastonia.
如果猶他盜龍和加斯頓龍偶遇，我覺得它們一般會避開對方，不過要是環境因素是極度干旱食物匱乏，那樣的事情會導致一次不愉快的碰面，我會認為猶他盜龍和所有掠食者一樣會被迫評估加斯頓龍的健康情況。
But with Gastonia, it's very tough to figure out a place where there was a chink in the amour.
不過就加斯頓龍來說，很難弄清楚它的身上哪塊護甲有裂縫。
But there was one piece of evidence that puzzled experts.
不過有一個證據讓專家們困惑。
The Gastonia skeleton had no marks or gashes in the bone.
加斯頓龍的骨架骨頭上沒有溝痕或印記。
Dinosaur expert George Blasing has an answer.
恐龍專家喬治·布雷興知道答案。
The reason why there were no bite and claw marks on the bones of the Gastonia is because its body was so well protected by body armor.
加斯頓龍骨頭上沒有咬痕和爪痕的原因是它的身體被體甲保護得非常好。
Even something as powerful as Utahraptor cannot bite through that armor to reach the bone below.
即使像猶他盜龍這么強壯的東西也無法咬穿其鎧甲碰到下面的骨頭。
And to make matters worse, that body amour was covered in a protective sheath of keratin.
雪上加霜的是，那個體甲上覆蓋著保護性的角質鞘。
So even if the raptor was able to leave bite marks in that keratin sheath, we would never see 'em because the keratin covering decomposes when the Gastonia dies, and that leaves behind no evidence whatsoever.
所以就算迅猛龍能夠在角質鞘上留下咬痕，我們也不會看到它們，因為角質層在加斯頓龍死后就會變質分解不會有任何證據留下來。
Only the belly and legs of the Gastonia lacked amour.
加斯頓龍只有腹部和腿部沒有裝甲。
It protected these soft spots from predators by hugging the ground.
它通過靠近地面移動來保護這些柔軟部分免受掠食者之害。
The Utahraptor was far more intelligent than the Gastonia, but was it smart enough to figure out a way to reach its vulnerable underbelly?
猶他盜龍要比加斯頓龍聰明得多，但是它是否足夠聰明能有辦法夠到加斯頓龍脆弱的下腹呢？
If we look at the physical strength comparing Utahraptor and Gastonia, Gastonia comes out ahead.
如果我們在身體強壯程度方面，把猶他盜龍和加斯頓龍進行對比，加斯頓龍更占優勢。
Utahraptor is strong, but it's a lightly built bird-like predatory animal.
猶他盜龍很強壯，不過它是體型較輕類似鳥類的肉食動物。
Gastonia is a very solidly built animal.
而加斯頓龍的構造非常結實。
It has to be physically strong to carry all that body armor.
它得足夠強壯才能撐起這全身鎧甲。
So, it's going to be, in just terms of sheer muscle mass, by far the more powerful of the two.
所以，這將是，僅從肌肉量來說，目前它（加斯頓龍）是兩者中更有力量的。
