我覺得異特龍不會與其它恐龍好好相處。
And so it makes sense to me that it would attempt to kill any competitor in its territory.
所以我覺得它會試圖殺死任何進入它領(lǐng)地的競爭者。
And so that's maybe what happened to the Ceratosaurus in the Colorado quarry.
所以那可能就是發(fā)生在科羅拉多石場的角鼻龍身上的事。
These're the animals lived in the same environment at the same time, in potential, would've been competitors.
這是兩種在同一環(huán)境下生活的動物,可能互相是競爭者。

One way to decrease competition is for each of them to actually take and specialize in different prey.
減小競爭的方法之一就是它們分別專門捕殺不同獵物。
But when prey was scarce, dividing up the food was not an option for either of these dinosaurs.
不過當獵物稀少時,對這些恐龍中的任何一個來說分配食物都不是一個選擇。
The prehistoric killing field found in Colorado proved that two major predators had come face to face at the Allosaurus feeding ground.
在科羅拉多發(fā)現(xiàn)的史前殺戮場證明了這兩種主要掠食者曾在異特龍的獵食地面對面地碰上。
When Allosaurus and Ceratosaurus fought, the Jurassic world was turned upside down as the hunter became the hunted.
異特龍和角鼻龍的大戰(zhàn)時,侏羅紀完全顛倒,獵人成了獵物。
Two of the largest predators in dinosaur history were on a collision course at the 150 million years old feeding ground of an Allosaurus.
在一億五千萬年前的異特龍獵食地,恐龍世界里兩種最大的掠食者正在對戰(zhàn)。
Investigators needed to come up with a new theory to explain why an interloper, another carnivore, would have made his move.
調(diào)查者要構(gòu)建新的理論來解釋為何另一種肉食動物,一個入侵者,會如此行動。
Paleontologists have re-examined the evidence to develop a scenario.
古生物學(xué)家為了重建場景而重新檢驗證據(jù)。
When we look at Allosaurus and Ceratosaurus, we are looking at fundamentally two different animals.
當我們研究異特龍和角鼻龍時,我們看到的是完全不同的兩種動物。
They had different ancestries.
它們有不同的祖先。
The Ceratosaurus comes from a group of dinosaurs that's much more ancient.
角鼻龍起源自一群更為古老的恐龍。
The Allosaurus on the other hand is a group of dinosaurs that appear later in time and has a slightly better body-built.
而異特龍則來自晚些時候的一組恐龍,身體也要稍微更好一些。
Allosaurus on average seems to be a little bit more heavily built than what we see in most of the Ceratosaurus specimens.
異特龍的平均體重要似乎比大多數(shù)的角鼻龍更重些。
So in a sense, Allosaurus is a sturdier kind of animal.
所以在某種意義上,異特龍是一種更強壯的動物。
Ceratosaurus wasn't a massive creature, but it certainly was a effective predator.
角鼻龍不是龐大的生物,但它卻是很有效率的掠食者。
