Eosinopteryx






How constrained is the fossil?  I've seen differing ages of between 120 to 140 million years old.  That's quite a range.

The press release is pretty bad.  I think that's pretty obvious now that feathers evolved as either for insulation or display first (or both) and then were adapted to flight.  The research seems overwhelming at this point.
