Angela Milner, like many paleontologists, believes the mega-carnivores were solitary creatures.
Angela Milner和許多古生物學(xué)家一樣，也認(rèn)為大型食肉恐龍營獨居生活
Traditional view of large meat-eaters dinosaurs behaviour was
傳統(tǒng)觀點認(rèn)為大型食肉恐龍
was that they were large, perhaps very ferocious animals, perhaps rabid predators, but probably living singlely.
是非常巨大兇殘的動物，狂暴的掠食者，但很可能是獨自生活
Large meat-eaters dinosaurs, there's no real evidence at all that they worked together in big groups.
大型食肉恐龍目前還沒有證據(jù)能證明它們會群體合作
Pack hunting is really hard to evolve.
群體狩獵是很難進(jìn)化的模式
And so, unless there's a reason for it to be there, I would, my default would be to say it's not there.
除非那里能有一些合理的原因。在我看來那是不可能的
For the skeptics, there is some convincing evidence to support their view of solitary predators.
對于那些持懷疑態(tài)度的人來說，很多有力的證據(jù)都能證明獨自狩獵的觀點
These are footprints made by dinosaurs.
這些是恐龍的腳印
They've been preserved in rock for over 150 million years.
它們保存在巖石中已有1億5千萬年
Mark Norell believes footprints like these show which kind of dinosaurs lived in groups.
Mark Norell認(rèn)為這些腳印能夠說明哪些恐龍營群居生活
The giant plant-eating dinosaurs left track-ways, fossilized footprints,
最大的植食恐龍留下了足跡，腳印化石
which really really show I think that they lived in groups or herds, whatever you want to call them.
這些腳印顯示它們生活在一個群體中，或者說是團(tuán)隊中，怎么說都行
And these footprints are not arranged randomly, they're arranged in groups.
這些腳印并非雜亂無章，而是很有序地排列
Which really shows that large ones walked in front of the packs, smaller ones in the middle of the packs
大的恐龍走在隊伍前面，小的恐龍走在中間，
and these groups had a structure and they're all going in the same direction.
整支隊伍按照一定的次序，一起朝同一方向前進(jìn)
And someplaces you can follow them for long stretches, long distances, hundreds and thousands of meters.
有時你能跟著它們走很長一段路、很長一段距離，幾百米或是幾千米
And you can see that they all move, sometime they all turn, and really seems to suggest that they're all moving together.
你會發(fā)現(xiàn)它們都是一起前進(jìn)，有時一起轉(zhuǎn)彎，它們都朝著同一方向前進(jìn)
It's not just a coincidence, they're all in the same direction.
這些事實說明它們走在一起并非偶然，
So I think this is really really powerful evidence, that suggestive of this sort of behavior in these animals.
這都是非常有力的證據(jù)說明了這些動物的行為
The evidence for giant carnivorous dinosaurs isn't as good.
但是大型食肉恐龍卻沒有這方面的證據(jù)
