侏羅紀(jì)搏擊俱樂(lè)部 第124期:超級(jí)砍家之名的由來(lái)

Utahraptor is the largest known member of the early Dromaeosaurids, which were birdlike meat-eating dinosaurs.

猶他盜龍是最大的已知早期馳龍成員，它們是類(lèi)鳥(niǎo)的肉食恐龍。

It killed by pouncing onto the back of its prey.

它們跳到獵物背上進(jìn)行獵殺。

If I were to design the perfect killing machine, I'd build a Raptor.

如果我要設(shè)計(jì)一種完美的獵殺機(jī)器，我就建造迅猛龍。

If I was gonna build the perfect Raptor, I'd build a Utahraptor because it's the right size for killing almost anything.

要是讓我建造一頭完美的迅猛龍，我就造猶他盜龍，其體型大小幾乎適合獵殺任何獵物。

Utahraptor stood nearly 2 meters tall, the height of a modern human.

猶他盜龍站起來(lái)近兩米高，跟現(xiàn)代人高度相仿。

But it was almost 4 times as long as it was tall and weighed in at half a ton.

不過(guò)它的長(zhǎng)度是高度的四倍，重量有半噸。

It had long powerful forelimbs, ending in three blade-like claws.

它的前肢長(zhǎng)而有力，末端有三個(gè)刀刃一般的爪子。

Its hind legs were short and sturdy with feet that each held his number one weapon -

它的后腿短而粗壯，每個(gè)腳上有它的頭號(hào)武器

A nine-to-fifteen-inch retractable sickle-shaped claw, giving it the nickname "super-slasher".

9到15英寸可自由伸縮的鐮刀形腳爪，給了它一個(gè)昵稱(chēng)叫“超級(jí)砍家”。

This is from the foot of Utahraptor, and it's unlike the claws in the feet of other theropods in that it's very narrow, you can see, it's narrow in section.

這來(lái)自猶他盜龍腳上的，它不像其它獸腳類(lèi)恐龍的腳爪，它非常窄，你能看到，這部分很窄。

And based on looking at the claws of modern birds, we realized this sheath was probably another third longer than this, so it'd come out and come out here, and go down here, before it got to a point.

基于對(duì)現(xiàn)代鳥(niǎo)類(lèi)腳爪的觀察，我們意識(shí)到這個(gè)護(hù)甲可能要比它還要長(zhǎng)三分之一，所以會(huì)出來(lái)，從這里出來(lái)，到那里，然后是爪尖。

And also, the sheath came to a sharp edge down here, much like a knife.

同樣護(hù)甲在這里也成了鋒利的邊緣，很像一把刀。

This supports the idea that they used this killer claw by putting it in and then pulling it along.

這證實(shí)了它們通過(guò)把它放進(jìn)獵物然后沿著拉它來(lái)使用這個(gè)獵殺爪的說(shuō)法。

Picture this animal being able to kick this thing with slashing strokes three and four, five-foot long strokes, plunge it in through skin an inch thick, slash down, ten inches deep, and cut three feet long.

可以想象一下這個(gè)動(dòng)物能夠踢腿并劃切這個(gè)東西，3到5英尺的一劃，陷進(jìn)一寸厚的皮膚，下切十英寸，切了3英尺長(zhǎng)。

And do that every couple of seconds.

每隔幾秒就來(lái)那么一下。

The discovery of the massive claws of Utahraptor proved that it was a formidable killer.

發(fā)現(xiàn)猶他盜龍巨大的爪子證明了它是可怕的殺手。

But investigators kept digging, and found something more.

不過(guò)調(diào)查者繼續(xù)挖掘，而且又有發(fā)現(xiàn)一些東西。

Broken teeth lay scattered nearby. They were from the raptor.

附近有散落下的牙齒。它們來(lái)自迅猛龍。

They were small, very sharp, and deadly.

牙齒較小、非常鋒利而且致命。

This is a Utahraptor tooth.

這是猶他盜龍的牙齒。

It's not that impressive perhaps, because the skull was,you know, perhaps about this long or so, but here you see it, it hasn't got a sharp point because this was used in life and it's worn, and it was shed, you can see little wear facets on here.

它也許沒(méi)那么令人印象深刻，因?yàn)轭^顱大概就是這么長(zhǎng)，不過(guò)能看到它一個(gè)尖端都沒(méi)有，因?yàn)樗怯眠^(guò)的，有磨損而且是脫落下來(lái)的，在這里能看到磨損的地方。
