The fossil find is a piece of jawbone, with a tooth, from a dromaeosaur.

这次发现的化石是带有一颗牙齿的奔龙颌骨。

The four wing dromaeosaur Microraptor was glossy black.

四翼驰龙小盗龙是有光泽的黑色。

The fossil is believed to be of a dromaeosaur.

据信这件化石是一只奔龙。

Dromaeosaurs had more narrow hips and were more lightly built than Therizinosaurus, for example.

例如，驰龙的臀部更窄，体型比镰刀龙更轻。

And later work would place them in the subgroup that also includes dromaeosaurs, like Velociraptor, Deinonychus, and birds.

后来的工作将它们归入还包括驰龙的亚组，如迅猛龙、恐爪龙和鸟类。

Falcarius shared an environment with a host of dromaeosaurs, troodontids, and early tyrannosaur relatives, so competitive pressure among carnivores was likely pretty high.

Falcarius 与许多驰龙、伤齿龙和早期霸王龙亲属共享一个环境，因此食肉动物之间的竞争压力可能相当高。

And while dromaeosaurs also had long arms, they didn't have the big claws on their hands that got Therizinosaurus mistaken for a clawed turtle.

虽然驰龙也有长臂，但它们的手上并没有大爪子， 这让镰刀龙被误认为是有爪的乌龟。

So far, Druckenmiller and his team have dug up species from seven different dino families: from big duck-billed dinos, ceretopsians, and tyrannosaurs to smaller thescelosaurs, leptoceratops, dromaeosaurs, and troodontids.

迄今为止，Druckenmiller 和他团队已经挖掘出7类恐龙：从大型鸭嘴恐龙、角龙、霸王龙到较小的奇异龙、纤角龙、驰龙和伤齿龙等。

So again there's a reversal there and it's telling you that, okay, Tyrannosaurs are using their mouth to kill, Dromaeosaurs are probably using their hands and feet more than anything else.

所以这里反转的现象说明，暴龙用嘴进行猎杀，驰龙则很可能用四肢用得最多。

" Certainly a place where things were capable of being cool at times but certainly warmer than the Arctic today." The fossil find is a piece of jawbone, with a tooth, from a dromaeosaur.

“当然，这个地方有时会很凉爽，但肯定比今天的北极更温暖。” 化石发现是一块来自驰龙的颚骨，上面有一颗牙齿。
