Probably, both dinosaurs were ultimately killed by drought.
有可能，兩頭恐龍最終都因干旱而喪命。
The fact that neither dinosaur had wounds on the bodies and that the bodies were relatively intact suggests that these dinosaurs didn't die in battle, they died because of environmental conditions, like a drought.

But early in the Cretaceous period, both species would eventually lose the bigger fight, becoming extinct.
不過在早白堊紀時期，兩個物種都逐漸在另一場更大的斗爭中敗下陣來，它們都滅絕了。
Why Utahraptor and Gastonia didn't go beyond the early Cretaceous is very difficult to say other than to speculate that it was like modern extinctions due to environmental factors, changes in patterns of food due to climate and things of this nature.
為什么猶他盜龍和加斯頓龍活過早白堊紀時期，這很難說，只能推測這是像現代滅絕現象一樣由環境因素造成的，氣候和其它自然變化導致食物模式的改變。
Larger herbivores were moving in and taking advantage of the foliage that little Gastonia couldn't have reached.

更大的植食動物帶來更大的掠食者，盡管猶他盜龍已經是相當危險的恐龍，它卻敗給了一種更大更兇殘的掠食者。
120 million years ago, dinosaurs were the planet's dominant species, but when conditions changed, their size and power couldn't help them.
一億兩千萬年前，恐龍是地球的主宰性物種，不過當條件改變時，它們的體型和力量也幫不了它們。
Too large and inflexible to adapt, they left only fossils to tell their story.
太過龐大且不靈活而不能適應（環境的改變），它們只留下化石來講述它們的故事。
