侏羅紀(jì)搏擊俱樂(lè)部 第95期:獵人成了獵物

I don't think Allosaurus played well with others.

我覺(jué)得異特龍不會(huì)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(jué)得它會(huì)試圖殺死任何進(jìn)入它領(lǐng)地的競(jìng)爭(zhēng)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(chǎng)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(dòng)物，可能互相是競(jìng)爭(zhēng)者。

One way to decrease competition is for each of them to actually take and specialize in different prey.

減小競(jìng)爭(zhēng)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(guò)當(dāng)獵物稀少時(shí)，對(duì)這些恐龍中的任何一個(gè)來(lái)說(shuō)分配食物都不是一個(gè)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(chǎng)證明了這兩種主要掠食者曾在異特龍的獵食地面對(duì)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(shí)，侏羅紀(jì)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(wàn)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(duì)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(lái)解釋為何另一種肉食動(dòng)物，一個(gè)入侵者，會(huì)如此行動(dòng)。

Paleontologists have re-examined the evidence to develop a scenario.

古生物學(xué)家為了重建場(chǎng)景而重新檢驗(yàn)證據(jù)。

When we look at Allosaurus and Ceratosaurus, we are looking at fundamentally two different animals.

當(dāng)我們研究異特龍和角鼻龍時(shí)，我們看到的是完全不同的兩種動(dòng)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(lái)自晚些時(shí)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(qiáng)壯的動(dòng)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。
