It also suggests that herbivory evolved in the crocodile clan on several occasions.

该研究还表明鳄鱼家族的食草性进化了好几次。

What particularly surprised Mr Melstrom and Dr Irmis, though, was the way herbivory mapped onto the crocodile family tree.

让Melstrom和Irmis博士感到特别惊讶的是这种食草性鳄鱼族谱上的方式。

This growth spurt might have initially occurred because some pelycosaurs were adapting to herbivory.

这一生长爆发可能最初是因为一些盘龙类正适应植食性。

And the thing that drove this group to herbivory?

是什么驱使这个群体食草？

Well, there are some real advantages to herbivory.

好吧，草食性确实有一些真正的优势。

This would mean that the therizinosaurs went from omnivory to herbivory, and were never carnivorous at all!

这意刀龙从杂食性转变为食草性，并且根本不是肉食性的！

The other fauna at Luoping may have also played a part in pushing Atopodentatus toward herbivory.

罗平的其他动也可能推动奇齿龙向草食性进化方面发挥了作用。

Or maybe it had other physiological adaptations, like longer intestines for fermentation that helped it get the most out of its food, which is how manatees make herbivory work.

或者它可能有其他生理适应，比如更长的肠道用于发酵， 帮助它最大限度地利用食，就像海牛那样让草食性成为可能。

But, in spite of how well specialized teeth worked for herbivory, plant-eating would actually lead to the loss of teeth in another vertebrate group: the weird mammal relatives known as dicynodonts.

但是，尽管特化牙齿对草食性动非常有效，吃植实际上会导致另一类脊椎动——奇特的哺乳动亲戚二齿兽——失去牙齿。

What particularly surprised Mr. Melstrom and Dr. Hermes though was the way herbivory mapped onto the crocodile family tree Rather than evolving once at some point long ago and then appearing in all later species on that branch.

特别让梅尔斯特罗姆先生和赫耳墨斯博士感到惊讶的是，草食性鳄鱼家族树上的分布方式。草食性并不是很久以前某一次进化后就出现该分支上所有后来的种中。
