Alone or in a group, this dinosaur's greatest strength was its colossal bulk.
無論是單獨或群體的腱龍，最大的優勢來自其龐大的身軀。
But despite its staggering power, the Tenontosaurus had two inherent weaknesses.
但盡管其力量驚人，腱龍仍存在兩個致命的弱點。
The first was its small brain.
其一是它的小腦袋。
A comparison of the brain to its body size suggests that these were not intelligent dinosaurs.
其小腦袋與龐大身軀的對比表明這些恐龍不是很聰明。
But in a fight, things are not always what they appear.
但是戰斗是并不總是像看起來那么簡單。
The crushed remains of four Raptors is clear evidence that Tenontosaurus hadn't given in straight away.
四頭迅猛龍被壓碎的遺骸就是明確的證據，這些腱龍是有辦法對抗攻擊的。
When you look at the fossil evidence, it suggests that the Raptors were crushed under some pretty impressive weight.
你看到化石上的痕跡便能明白，這些迅猛龍是被超出想像的重量壓碎的。
Had the Tenontosaurus crushed him with his foot,
腱龍用腳猛踩迅猛龍時，
I think their bodies would have looked like pancakes because you had all of its weight being focused on that small foot area.
我猜它們的身體會被踩的像煎餅一樣，因為腱龍的體重集中在腳上。
But because their bodies were relatively intact, I think they were either crushed by the tail or, more likely, they were crushed under the weight of this animal.
但由于它們的遺骸相對完整，我猜它們是被尾巴壓碎的，或更可能是被這種動物的龐大身軀壓碎的。
To help formulate the hypothesis for this gang killing, paleontologists began to piece together various scenarios of how the Raptors singled out the plant-eater.
為了重現群體獵殺的畫面，古生物學家開始拼湊迅猛龍挑揀草食恐龍的各種場景。
They would probably stalk their prey, maybe one would get up and size up and try to pick out the weakest one, maybe get them all running and getting the slowest one, so then they would take after that slowest one.
它們或許會悄悄跟蹤獵物，也許有只會站起來看看它們的體型，選最弱的個體，讓它們跑起來找出最慢的，然后對那頭最慢的下手。
And maybe they would take turns chasing it around, tiring it.
而且它們可能輪班追逐以消耗獵物體力。
As soon as it was enough where one could jump on its back, all the rest of them would join and it would be curtains for that Tenontosaurus.
待時機成熟，一頭迅猛龍便跳到腱龍背上，此時所有的一起出擊，腱龍也就到了危機關頭。
Like wolves, I suspect, that these animals would attack from different directions.
我覺得它們很像狼，可能會從不同的方向出擊。
They would take their chance to come in when the attention of the Tenontosaurus was attracted somewhere else.
腱龍的視線被干擾時，它們會抓住機會從另一側攻擊。
So its key to success was get in there, tear holes in it, rip open that belly,
因此它們成功的關鍵是跳上獵物、撕出傷口、開膛破肚，
and then as more and more of them strike, it just gets weaker and weaker until it collapses and then they can come in and feast.
隨著攻擊者越來越多，獵物變得愈來愈弱直到癱倒在地，接著它們便開始大快朵頤了。
Under attack from a pack of Raptors, the Tenontosaurus herd would instinctively scatter.
在迅猛龍群的圍攻之下，腱龍群本能的四散逃開。
If separated from the group, the lone Tenontosaurus had to rely on anything available, including the environment.
倘若從獸群分散，獨行的腱龍只能依靠各種防御武器包括環境。
I think its main way of surviving would be to get in a place where the attackers couldn't come at it from all the sides.
我認為要想能活下來，它就得逃到一個攻擊者無法不同方向進攻的地方。
So if it went into like denser vegetation, into the forest, running through the brush to help protect its flanks from attackers.
所以如果腱龍跑進濃密的樹叢、跑進森林里或是穿過灌叢，攻擊者就很難從側面襲擊。
That would probably be its safest course.
這可能是最安全的策略。
