These include the ornithomimosaurs and the oviraptorosaurs.

这些包括似鸟龙和偷蛋龙。

However, most experts think that--in addition to plants--ornithomimosaurs probably ate insects and small animals.

然而，大多数专家认为——除了植物——似鸟龙可能还吃昆虫和小动物。

But there was a trade-off: Because of its size, Deinocheirus wasn't as fast as some other ornithomimosaurs.

但有一个权衡：由于它的体型，恐手龙没有其他一些似鸟龙恐龙快。

Scientists estimate that certain ornithomimosaurs might've had a top running speed of anywhere from 35 to 60 kilometers per hour!

科学家估计，某些似鸟龙的最高奔跑速度可能达到每小时 35 至 60 公里！

And, unlike some of the speedier ornithomimosaurs, Deinocheirus had relatively short legs, tipped with blunt claws that resembled hooves because of their squared-off tips!

而且，与一些速度更快的鸟龙不同，Deinocheirus的腿相对较短，尖端有钝的爪子，因为它们的尖端是方形的，所以类似于蹄子！

As far as feeding goes, it's been hypothesized that some ornithomimosaurs used their long arms and slender fingers to grasp fern fronds and tree limbs.

就进食而言，有人假设某些似鸟龙类使用它们的长臂和细长的手指来抓取蕨类植物的叶子和树枝。
