Let's return to the microraptor fossil.

让我们回到小盗龙的化石。

Among the artifacts was a microraptor fossil estimated to be approximately 120 million years old.

其中一件是古生物小盗龙化石，距今约1亿2千万年。

Paleontologists identified a tiny foot behind the fossilized 120 million-year-old rib cage of a crow-sized microraptor.

古生物学家在1.2亿年前乌鸦大小的小盗龙的胸腔化石后面发现了一只小脚。

And from those imprints, we can determine that these microraptor feathers were similar to modern dinosaur, as in bird, feathers.

从这些痕迹中，我们能知道这些盗龙的羽毛和现代的恐龙很相似，就像鸟类的羽毛。

They compared these microraptor melanosomes to those of modern birds and found a close similarity, though not a perfect match, to the iridescent teal feathers found on duck wings.

他们还把这只盗龙的黑色素体拿来和现代的鸟类做比较发现盗龙羽毛中的黑色素体和拥有闪色的羽毛的水鸭，尽管不是完全吻合，但是仍然存在许多相似之处。
