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 。

Like Sauropods, Prosauropods had small heads and long necks.

像蜥脚类一样，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，原蜥脚类显示了侏罗纪开始早期迹象。

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.

许多原蜥脚类也有抓握手和仅用后脚站立和行走能力。

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方向前进——认为它们可能是晚期存活原蜥脚类动物，即被称为蜥脚类动物长颈巨型食草动物祖先。

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.

这些有食草动物臀部、长长手臂和长长爪子，就像巨地懒，还有像原蜥脚类动物一样四趾脚。

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.

原蜥脚类不仅是三叠纪晚期环境中最食草动物，而且还是迄今为止进化过最陆生食草动物。

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.

尽管在时代初期，原蜥脚类非常成功，但该群体时间很短，很快就被更先进食草所取代。

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.

原蜥脚类是早期食草群体，比它们巨型蜥脚类表亲小得多，但小是相对，一些原蜥脚类动物长度仍超过 10 米，重量超过 3 吨。
