Such reptiles , in fact , lived several million years before the first dinos emerged .

事实上，它们生活的年代要比第一种恐龙出现的年代还要早数百万年。

The researchers think those long tendons may have allowed the dinos to shift muscle mass from their necks onto their bodies-giving them a sort of " remote control " over their necks , while making the neck lighter and more flexible .

研究人员认为，那些长长的肌腱使得这些恐龙能够将肌肉的质量通过脖子传递到身体上，这不仅使得它们能够“远程控制”它们的脖子，也使得脖子变得更灵活轻便。
