"This study gives us an unprecedented glimpse at what this animal looked like when it was alive," said Mark Norell, one of the paper's authors and chair of the American Museum of Natural History's Division of Paleontology. "There's been a lot of speculation about how the feathers of Microraptor were oriented and whether they formed airfoils for flight or whether they had to do with sexual display. So while we've nailed down what color this animal was, even more importantly, we've determined that Microraptor, like many modern birds, most likely used its ornate feathering to give visual social signals."
Although its anatomy is very similar to birds, Mircroraptor is considered a non-avian dinosaur and is placed in the group of dinosaurs called dromaeosaurs that includes Velociraptor. The fossilized specimen used in this study comes from rocks in Northeastern China that are about 130 million years old.
