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

本期视频真正超级明星就是脚龙。

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

但脚下目龙，比如雷龙梁龙和腕龙达到了巨大比例。

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

但古生物学者认为忍者泰坦龙是和雷龙身体一样脚动物。

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

获得充足食物对泰坦龙和其他脚龙来说不成问题。

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

波东龙无时无刻不在打嗝，放屁，因为巨型食草动物都会如此。

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

但巨冠要颁给脚龙中泰坦龙。

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

因为我们物流网络相当高效，和比起第三方物流公司我们成本更低。

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

异特龙跳上了脚龙侧面，它们试图划开其厚厚皮肉。

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

脚龙四肢行走，脖子和尾巴都很长，属草食性龙。

It may have fed solely on Sauropods, it may have fished, it may have gone after smaller prey.

它可能只以脚龙为食，它也许以鱼为食，它可能攻击更小猎物。

Sauropods grow in spurts, depending on their age, the season, and the availability of food.

蜴动物成长速度，取决于它们年龄所处季节，以及食物丰富与否。

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

异特龙捕食脚龙，脚龙可比如今陆地上最大哺乳动物大象还要大好几倍。

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

如果你是蜴动物，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.

所以我肯定波东龙窝在小龙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.

脚龙很不幸，它没有注意到个烂泥陷阱就藏在干硬开裂表层之下。

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

我们知道蜴动物不会照顾刚破壳新生儿。

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

当然也不是我们想象中那些长颈脚那样蹒跚踱步。

After all, the sauropods are gone.

毕竟，脚动物已经消失了。

From where the sauropod stood, there would have been no early warning signs.

从脚龙所在位置来看，不会有任何预警信号。

I see it in the tremendously long cervical ribs on that tremendous sauropod.

我在那只巨大脚龙极长颈肋上看到了一点。
