How cool!!!  Considering modern glossy-black birds (starlings, crows, ravens, grackles, etc) are quite social, I bet Microraptor was quite social as well. The only part I don't get is this: "Spherical melanosomes tend to be reddish-brown, while rod-like ones are black or grey." Is that the only colors melanosomes can make, or at least be preserved in fossils? So there aren't melanosomes for yellow or blue?  |

That´s nearly unbelieveable news! Now, if I´m right, this is already the second dinosaur whose colour could at least in parts be identified, right?!

Actually, this makes it at least number four.
Anchiornis
Sinosauropteryx
Archaeopteryx
Microraptor
I admit, I don't relish the idea of the Carnegie Microraptor being repainted.

Is that the only colors melanosomes can make, or at least be preserved in fossils? So there aren't melanosomes for yellow or blue? There are no melanosomes for anything but brown, grey/black, and rusty red and pale yellow (see colors of mammal hair, chick down, etc.) Colors like red and yellow are made by caretinoids. Blue, green, purple etc. are made by irridescence alone. If there were blue melanosomes, we could conceivably have blue-haired mammals. Blue melanosomes HAVE evolved in one type of frog and one type of fish, and green melanosomes have evolved in one type of bird (turaco), so it's not impossible, but very, very, very unlikely in most other theropods. See my post here for more: dinogoss.blogspot.com/2010/10/guide-to-feather-colors.htmlNote that this is a bit out of date. i've since heard that the biological pathways that allow birds to take carotenoids from their food and use it to color their feathers evolved only in neognahe birds. Anything more primitive than that probably could not have had bright red or yellow feathers aside from iridescent effects. |

Amazing! I wouldn't mind a repaint of the Carnegie Microraptor - accuracy over style, in my book - but then the tail feathers would still be wrong. I say an entirely new sculpt is in order  Actually, this makes it at least number four. Anchiornis Sinosauropteryx Archaeopteryx Microraptor Wait, what color was Archaeopteryx? |

It had at least one black feather. Only one feather was tested, unlike the Microraptor paper where numerous feathers were tested from various parts of the body. |
