RE: Dino feather and ptero "fur" homology

A shame, really. Fuzz at the base of Ornithodira (or below) is a damn cool concept!

George Olshevksy's "BCF" proposes something along these lines. Something to do with feathers, pterofuzz, and scutes all being homologous (I think). The idea is highly imaginitive, but so far lacking in scientific data.
