These include the ornithomimosaurs and the oviraptorosaurs.

这些包括似鸟龙和偷蛋龙。

Regardless, while Deinocheirus was an ornithomimosaur through and through, it didn't just look like a scaled-up Ornithomimus.

无论如何，虽然恐手龙是彻头彻尾的似鸟龙，但它看起来不仅仅是放大的似鸟龙。

These have been seen in a few other non-avian dinosaurs, but nobody had ever found one on an ornithomimosaur before!

这些已经在其他一些非鸟类恐龙身上看到过，但以前从来没有人在似鸟龙身上发现过！

Your typical ornithomimosaur ranged from around 2.5 to 7 meters long.

典型的似鸟龙类动物身长约 2.5 至 7 米。

Still, as time went by, most experts agreed that Deinocheirus was probably an ornithomimosaur--just an exceptionally big one.

尽管如此，随着时间的推移，大多数专家都认为恐手龙可能是一只似鸟龙类——只是一只特别大的恐龙。

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。

But without the rest of the body, paleontologists couldn't say whether Deinocheirus fit the typical mold of an ornithomimosaur.

但是如果没有身体的其他部分，古生物学家无法判断恐手龙是否符合典型的似鸟龙模型。

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 some anatomical clues--like the toothless beak--showed that scientists were right in thinking that Deinocheirus was a gigantic ornithomimosaur.

一些解剖学线索——比如没有牙齿的喙——表明科学家们认为恐手龙是一种巨大的似鸟龙是正确的。

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。

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。
