　　我们在石场工作，我们开始对骨头是如何放置的熟悉起来。

　　And one of the students that was with the College of Eastern Utah, yelled over to me:

　　在东犹他大学就读的一名学生向我喊道：

　　"Jim, you should come over and look at this. It looks a little different."

　　“吉姆，你得过来看看这个。看起来有点儿不一样”

　　And I'm looking down at it, and I realize that there's a little groove³ on the surface.

　　我向下看去，意识到在其表面有一条小沟槽。

　　And I hold my head down low and realize "Boy, this is really thin. That looks like the groove you see in the side of a claw,but it's really thin."

　　把头低下去后发现“天哪，这真薄。看起来好像是爪子侧面的沟槽，不过真是很薄。”

　　And I thought to myself, "Deinonychus, terrible claw, from the early Cretaceous."

　　我想，“恐爪龙，可怕的爪子，来自白垩纪早期。”

　　"This is good, one of my favorite dinosaurs⁵." I said, "This is twice as big as Deinonychus".

　　“不错，是我最喜欢的恐龙之一”，我说，“但这有恐爪龙两倍大”。

　　Scientists had just unearthed⁶ the remains⁷ of a giant raptor, one that was over 12 times as heavy as its next largest relative.

　　科学家们刚刚挖出了巨大的迅猛龙骨骸，是其最大亲戚体重的十二倍。

　　They named the beast Utahraptor.

　　他们给这头猛兽起名犹他盗龙。

　　Very soon after beginning to excavate⁸ the Gastonia bones, we uncovered a claw approximately 8 inches in length.

　　我们挖掘出加斯顿龙骨头之后很快，我们就发现了一个接近8英寸长的爪子。

　　And through analysis of other specimens⁹, it was determined¹⁰ that this was a gigantic Dromaeosaur, which is the family of dinosaurs that Velociraptor and Deinonychus and things like that belong to.

　　通过分析其它样本，它被确定是一种巨大的恐爪龙，伶盗龙和鳄龙以及类似这些都属于的这个恐龙科。

　　And so this was very exciting because it was the largest Dromaeosaur known and not only it was larger than anything known, but it was several times larger than anything previously¹¹ seen.

　　所以这很让人兴奋因为这是已知最大的恐爪龙，不仅比任何已知的都大，而且要比以前看到的大好几倍。

　　The Utahraptor preceded the Velociraptor by tens of millions of years.

　　犹他盗龙比伶盗龙早出现几千万年。

　　This was clearly an early version of the smaller, faster raptors to come.

　　这显然是后来的更小更快的迅猛龙的早期版本。

　　When Utahraptor was found, it was pretty significant because up until that point the largest of the Raptor dinosaurs found was Deinonychus, which was about the size of a timber wolf.

　　犹他盗龙被发现的时候，非常有意义，因为到那时为止，人们发现的最大迅猛龙是鳄龙，其体型与一头灰狼相仿。

　　And here comes one with similar sort of anatomy¹², but bigger than a bear, or at least the size about a big grizzly¹³, or a big polar bear, a truly monster sized Raptor dinosaur⁴.

　　而这一头有着类似的解剖结构，但却比熊大，或者最少是一头大个儿棕熊或大北极熊的体型，真正的怪兽级别的迅猛龙。

　　I think someone gave a really good explanation of what Utahraptor was.

　　我记得有人对犹他盗龙是什么做了非常好的解释。

　　Utahraptor was Velociraptor on steroids. Here's the pumped up Raptor.

　　犹他盗龙是服了类固醇的伶盗龙。这是振奋的迅猛龙。

　　This is the biggest Raptor we've found so far and it was probably the nastiest as well.

　　这是到目前为止发现的最大的迅猛龙，而且很可能是最凶狠的。
