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

本期视频的真正超级明星就是蜥脚类。

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

但蜥脚下目类的，比如雷梁和腕达到了巨大的比例。

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

但古生物学者认为忍者泰坦是和雷的身体一样的蜥脚类动物。

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

获得充足的食物对泰坦和其他蜥脚类来说不成问题。

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

波东不在打嗝，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.

但巨冠要颁给蜥脚类中的泰坦。

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

因为我们的物流网络相当高效，和比起第三方物流公司我们的成本更低。

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

异特跳上了这头蜥脚类的侧面，它们试图划开其厚厚的皮肉。

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

蜥脚类四肢行走，脖子和尾巴都很长，属草食性。

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

它可能只以蜥脚类为食，它也许以鱼类为食，它可能攻击更小的猎物。

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

蜥蜴类动物的成长速度，取决于它们的年龄所处季节，以及食物的丰富与否。

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

异特捕食蜥脚类，蜥脚类可比如今陆地上最大的哺乳类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.

如果你是蜥蜴类动物，那你就所指望。只有长大才是王。

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

所以我肯定波东的窝在小还没孵出来就被捕食者给毁了。

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

这头蜥脚类很不幸，它没有注意到这个烂泥陷阱就藏在干硬开裂的表层之下。

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

我们知蜥蜴类动物不会照顾刚破壳的新生儿。

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蜥脚类那样蹒跚踱步。

After all, the sauropods are gone.

毕竟，蜥脚类动物已经消失了。

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

从蜥脚类所在的位置来看，不会有任何预警信号。

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

我在那只巨大的蜥脚类极长的颈肋上看到了这一点。
