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

原蜥脚类恐龙也有抓握的手和仅用后脚站立和行走的能力。

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

特别是，原蜥脚类恐龙显示了侏罗纪开始的恐龙统治的早迹象。

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——认为它们可能是晚存活的原蜥脚类动，即被称为蜥脚类动的长颈巨型食草动的祖先。

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.

这些恐龙有食草动的臀部、长长的手臂和长长的爪子，就像巨大的地懒，还有像原蜥脚类动一样的四趾脚。

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.

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

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.

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

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.

原蜥脚类恐龙是早的食草恐龙群体，比它们的巨型蜥脚类恐龙表亲小得，但恐龙的大小是相对的，一些原蜥脚类动的长度仍超过 10 米，重量超过 3 吨。
