But they were no match for the real giants of the era, Prosauropods.

但它们都不是这个时期真正的巨人，原蜥脚类。

And it's this anatomy that enabled Prosauropods to evolve into the largest dinosaurs of all time.

正是这种解剖学使原蜥脚类进化成历史上最大的恐 。

Like Sauropods, Prosauropods had small heads and long necks.

像蜥脚类恐一样，原蜥脚类动物有小头和长子。

In particular, prosauropods show early hints of the dinosaur domination that was to begin in the Jurassic.

特别是，原蜥脚类恐了侏罗纪开始的恐统治的早期迹象。

However, there is a third, shorter lived and less diverse group, the Prosauropods.

然而，还有第三种寿命较短且种类较少的类群，即原蜥脚类动物。

Many Prosauropods also had grasping hands and the ability to stand and walk only on their back feet.

许多原蜥脚类恐也有抓握的手和仅用后脚站立和行走的能力。

Others went in a completely different direction – thinking that they might be late-surviving prosauropods, the ancestors of the long-necked giant plant-eaters known as sauropods.

其他人则朝着完全不同的方向前进——认为它们可能是晚期存活的原蜥脚类动物，即被称为蜥脚类动物的长颈巨型食草动物的祖先。

These dinosaurs had the hips of a plant-eater, long arms that ended in long claws like a giant ground sloth, and four-toed feet like prosauropods.

这些恐有食草动物的臀部、长长的手臂和长长的爪子，就像巨大的地懒，还有像原蜥脚类动物一样的四趾脚。

Prosauropods were not only the largest herbivores in any late Triassic environment, but they were also the largest terrestrial herbivore that had ever evolved up to that point.

原蜥脚类恐不仅是三叠纪晚期环境中最大的食草动物，而且还是迄今为止进化过的最大的陆食草动物。

Although, at the beginning of the age of dinosaurs, Prosauropods were highly successful, the group had a short reign and was soon replaced by more advanced herbivorous dinosaurs.

尽管在恐时代初期，原蜥脚类恐非常成功，但该群体的统治时间很短，很快就被更先进的食草恐所取代。

Prosauropods were an early group of plant eating dinosaurs and were much smaller than their giant Sauropod cousins but dinosaur size is relative and some Prosauropods still measured over 10 meters in length and weighed over 3 tons.

原蜥脚类恐是早期的食草恐群体，比它们的巨型蜥脚类恐表亲小得多，但恐的大小是相对的，一些原蜥脚类动物的长度仍超过 10 米，重量超过 3 吨。
