The real super-stars of the show are the sauropods.

本期视频真正超级明星就是蜥。

But it was the sauropods like Brontosaurus, Diplodocus and Brachiosaurus who reached enormous proportions.

但蜥下目，比如雷梁和腕达到了巨大比例。

But paleontologists believe that ninjatitans were sauropods with bodies like brontosaurus.

但古生学者认为忍者泰坦是和雷身体一样蜥动。

But the colossal crown goes to a group of sauropods called titanosaurs.

但巨冠要颁给蜥中泰坦。

Reaching enough food wasn't a problem for the titanosaurs and other sauropods either.

获得充足食对泰坦和其他蜥来说不成问题。

Because our logistic system is quite efficient, and a lower cost compared with sauropod a logistic delivery companies.

因为我流网络相当高效，和比起第三方流公司我成本更低。

The Allosaurus leap onto the side of the sauropod, they're trying to cut through the thick flesh.

异特跳上了这头蜥侧面，它试图划开其厚厚皮肉。

Certainly not as sort of plodding as what we think many of the long-necked Sauropods were like.

当然也不是我想象中那些长颈蜥那样蹒跚踱步。

Sauropods are dinosaurs that walked on four legs, had long necks and tails and ate plants.

蜥四肢行走，脖子和尾巴都很长，属草食性。

Allosaurus's feeding on sauropods, animals that're multi-times the size of our largest mammals today, the elephant.

异特捕食蜥，蜥可比如今陆地上最大哺乳动大象还要大好几倍。

We know that the sauropods were not taking care of their newly hatched babies.

我知道蜥蜴动不会照顾刚破壳新生儿。

And if you're a sauropod, you've got nothing else. So getting big is the only game in town.

如果你是蜥蜴动，那你就无所指望。只有长大才是王道。

So I'm sure that many, many sauropod nests were found and destroyed by predators before the babies could even hatch.

所以我肯定波塞东窝在小还没孵出来时就被捕食者给毁了。

Unfortunately for this sauropod, it's unaware of the mud trap that lies just beneath the cracked and dry upper crust.

这头蜥很不幸，它没有注意到这个烂泥陷阱就藏在干硬开裂表层之下。

From towering long-necked sauropods to fierce velociraptors, these ancient creatures have captivated our attention for generations.

从高大长颈蜥到凶猛迅猛，这些古老生已经吸引了我几代人注意力。

If I wanted to grow a 200-ton Sauropod, that's where I'd start...with about seven more pounds of brain.

如果我要养一头两百吨重波塞东，我就要从这个大约七磅重大脑开始。

Or a footprint of a giant sauropod dinosaur.

或者巨型蜥印。

Sauropods were probably burping and farting almost continuously, because that's what big plant eaters do.

波塞东无时无刻不在打嗝，放屁，因为巨型食草动都会如此。

Sauropods are part of a larger group of dinosaurs called the sauropodomorphs, or sauropod-like dinosaurs.

蜥是更大群一部分，称为蜥或蜥。

Very early sauropods like Massospondylus, had legs somewhere in between these two extremes.

非常早期蜥，如大椎，其腿介于这两个极端之间。
