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。

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

正是这种解剖使原蜥脚进化成历史上最的龙 。

Like Sauropods, Prosauropods had small heads and long necks.

像蜥脚龙一样，原蜥脚有小头和长子。

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

特别是，原蜥脚龙显示了侏罗纪开始的龙统治的早期迹象。

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较少的群，即原蜥脚。

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

许多原蜥脚龙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，即被称为蜥脚的长颈巨型食草的祖先。

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.

这些龙有食草的臀部、长长的手臂和长长的爪子，就像巨的地懒，还有像原蜥脚一样的四趾脚。

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.

原蜥脚龙不仅是三叠纪晚期环境中最的食草，而且还是迄今为止进化过的最的陆生食草。

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.

尽管在龙时代初期，原蜥脚龙非常成功，但该群体的统治时间很短，很快就被更先进的食草龙所取代。

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.

原蜥脚龙是早期的食草龙群体，比它们的巨型蜥脚龙表亲小得多，但龙的小是相对的，一些原蜥脚的长度仍超过 10 米，重量超过 3 吨。
