侏羅紀搏擊俱樂部 第43期:以一敵百的恐爪龍

Tenontosaurus is a very sturdy, strongly builtanimal.

腱龍是一種體格強健結實的動物。

The bones are very large and those bones wereclothed with relatively powerful muscles to carry thelarge animal around.

它的骨頭很大，而且上面蓋覆著強健的肌肉以支撐起這個龐然大物。

Deinonychus as an animal was certainly a very stronganimal.

恐爪龍無疑是非常強壯的動物。

But we think about its skeletal structure, it's relatively delicate.

但從它的骨骼結構來看還是比較脆弱的。

Tenontosaurus is definitely a far more powerful dinosaur.

而腱龍絕對是強健得多的恐龍。

It's larger. It's a far bigger animal... More powerfully built. More solid bones.

它更大、體型要大得多...有更強有力的體格、更結實的骨骼。

A lot more muscle.

肌肉也多得多。

The size difference between Tenontosaurus and Deinonychus suggests that in order to attackone, the Deinonychus would be forced to hunt cooperatively, to have any chance of bringing itdown.

從腱龍和恐爪龍的體型差異來看，恐爪龍要想攻擊腱龍，它們就必須得合作獵食，這樣才能有機會殺死腱龍。

If the Deinonychus was in a group, then the group might be able to overwhelm theTenontosaurus, but it'd be awfully dangerous.

如果恐爪龍是一群，那么腱龍可能會應接不暇，不過這仍然會是十分危險。

A pack of Deinonychus will be a closer match to an individual Tenontosaurus.

一群恐爪龍跟一頭腱龍難分高下。

So if you've got a whole bunch of Deinonychus operating together, you have about the samemuscle strength as you have with a single Tenontosaurus.

所以如果一群恐爪龍相互合作，就相當于有了腱龍一樣強健的肌肉。

The Raptors body design suggests that when it came to speed and agility, it had the upperhand.

從迅猛龍的身體構造來看，它有驚人的速度和機動性，這是它的優(yōu)勢。

Without a doubt Deinonychus is definitely a faster, more agile animal than Tenontosaurus.

無可否認，恐爪龍的速度比腱龍要快，也比腱龍更靈活。

You look at the individual bones of a Deinonychus and they're, they're quite narrow.

看看恐爪龍的每塊骨頭，它們是很窄的。

Its whole structure was built to be able to move quickly and in an agile way.

其整體構造都是為了更加快速且靈活的行動方式。

Agility-wise Tenontosaurus is certainly much better off than, any of the Ceratopsians orSauropod dinosaurs.

任何角龍類和蜥腳類的恐龍都沒有腱龍靈活。

Because Tenontosaurus can be functionally bipedal so that gives it a lot more turn ability.

因為腱龍可以雙腿直立，所以轉身的幅度可以很大。

It's got a fairly rigid tail.

它還有一條很硬實的尾巴。

One of the main reasons why Raptors are so fast is because of their lung design.

迅猛龍如此之快，主要原因之一是它們的肺部構造。

As they breathe in, the air travels into their lungs and then from there, is forced into variousbones and vertebra.

由于它們呼吸進入肺部的空氣被強制推進到各根骨骼和脊椎。

That air then ultimately exits the body through holes in some of bones.

空氣最終通過一些骨頭上的小孔排出體外。

It doesn't waste energy pushing that air back out of its throat, so it's at full throttle all thetime.

它不用浪費精力讓空氣從喉嚨呼出，因此它們總能保持精力旺盛。

Deinonychus was all about agility. Moving around, quickly.

恐爪龍非常靈活。且行動快捷。

Rapidly making quick turns, quick movements of its head and neck.

急速轉彎時它的頭部和頸部也能很快活動。

We have lots of evidence that that was important for Deinonychus both from its skeleton,

我們有諸多證據(jù)顯示恐爪龍的骨架對其是極為重要的，

but also from the way its brain and inner ear were structured which again show very importantsigns, of quick, relatively rapid movements being important for Deinonychus.

而且從它的腦部和內耳的結構也發(fā)現(xiàn)了非常重要的跡象表明，迅速移動對恐爪龍而言，也是舉足輕重的。

That's not the case for Tenontosaurus.

但是腱龍就不是這樣了。
