This was typical with plant eaters, but less commonly seen in predators before this time.

这在植食性动物中很典型,不过在此前的掠食者中并不常见。

What's interesting with Allosaurus, we find large accumulations of Allosaurus's bone.

异特龙有趣的是,我们找到异特龙骨头大量积累。

That's unusual 'cause we tend not to find that with predatory animals of any kind, not just dinosaurs.

那很不寻常,因为我们往往不会找到那个,不只是恐龙对任何掠食者来说都是。

It's when we see large accumulations that makes us wonder what's going on.

我们看到大量的骨头后时就开始琢磨这是怎么回事。

Did these animals live in large groups?

这些动物成群活动吗?

One might even call them flocks considering they're closer related to birds.

有人也许甚至会叫他们恐龙群,考虑到它们跟鸟类密切相关。

Family groups are very effective for predators because hunting on your own, your chances of success are limited.

家族群体对于掠食者来说非常有效,因为单独狩猎的成功几率有限。

They are up against some pretty tough paraders back then.

那时候跟它们竞争的对手也很强大。

Some of the things they preyed on could've killed them very easily.

有些它们捕猎的对象能够轻易地杀死它们。

So by living in a family group and hunting in a family group, it ensures your chance of survival.

所以在家族群体里生活和捕猎,保证了生存的机会。

And there is another key difference.

还有另一个主要的区别。

The Allosaurus was an intelligent creature with a capacity to form strategies.

异特龙是聪明的生物,有能力组织策略。

We're very interested to have the opportunity to CAT scan the skull of Allosaurus because in terms of its position in the family tree of predatory dinosaurs, it was kind of right in the middle.

我们很乐于对异特龙头骨进行CAT扫描,因为在掠食性恐龙的系谱图里,它的位置正在中间。

It wasn't like the more primitive dinosaurs, like Majungasaurus, and it wasn't like the really sort of very bird-like dinosaurs, like Deinonychus.

它不像那些更为原始的恐龙,比如玛君龙,也跟那些很像鸟的恐爪龙等不同。

Allosaurus was the most sophisticated of the late Jurassic animals.

异特龙是后侏罗纪时期最为复杂的动物。

Among the large meat eating animals, it probably had the most sophisticated mental capacities.

在大型食肉动物里,它的可能拥有最复杂的心智能力。

No genius by any means, but smarter probably than any other large predators within its environment.

肯定算不上十分聪明,但肯定比它的环境里其它大型掠食者要更聪明。

This always would give it advantage over these other predatory dinosaurs.

与其它掠食恐龙相比这一点是它的优势。

Its senses were probably a bit more acute and the way their mind would process the sensory information, ahh, probably was more efficient.

它的感官可能更灵敏,它们的头脑处理这些感觉信息,也很可能更有效。

During the Jurassic period, Allosaurus was the most sophisticated predator.

在侏罗纪时期,异特龙是最先进的掠食者。

To accompany its intellect, it had three invaluable adaptations.

伴随它的智力,它还有三个难得的适应性的改变。

The first, a jagged array of serrated teeth rooted in jaws that could crush steel.

第一就是满口参差的能够咬穿钢铁的锯齿状牙齿。
