Re: AW: Heterodontosaurid with protofeathers

New Scientist has my take on the story


I talked with Alan Brush who says the "protofeathers" were hollow unbranched 
structures, just as he and Rick Prum had predicted the ancestral form would be. 
I'm no expert, but it's looking plausible that some kind of filamentary fuzz 
might have been primitive within archosaurs after the crocodiles split off. Or 
perhaps before; it could be that the fuzz was easy to lose.
