RE: Microraptor Had Iridescent Plumage

Do you agree with me that there is also no positive evidence of feathers on the
tip of the snout?
In NGMC 91 (Dave) we see an orderly decrease in the size of the feathers -
growing shorter rostrally. No more feathers are preserved by the time we reach
the proximal border of the nostril. Sinornithosaurus is Microraptor's closest
relative according to most phylogenies.
There are also no feathers preserved on the distal rostrum in any other
specimen, be it Microraptor or any other taxon.
There are also none on birds.
Therefore don't you agree that the hypothesis that is most consistent with the
evidence is that of a bare distal rostrum?

Oh yes. And lovely paper and lovely supplementary information, too!

They're not sprawled. Instead, the lower legs are rotated.
You can do that, I can do that -- the European honey buzzard can do that, and
no other dinosaur can.
I hate it when such artistically great images are completely ruined by utter
anatomical impossibilities. Now every time I show that picture to someone, I'll
have to add that disclaimer!
The fingers are rotated, too: the claws should point into the page, not
And there's still no evidence for naked skin (or scales) on the snout.
I'd have made two drawings, one in dorsal view and one in lateral view, to show
the fore- and hindwings. Lateral view would also allow showing a hand in palmar
