Re: AW: Heterodontosaurid with protofeathers

<<We have evidence of fur in _Docodonta_ and (of course) in _Mammalia_, so it probably existed in some common ancestor of those two clades, but not prior to the sauropsid-synapsid split. In fact, since _Estemmenosuchus_, a dinocephalian stem-mammal, is supposed to have been scaly, it may have been after the dinocephalian-neotherapsid split (see: http://en.wikipedia.org/wiki/Therapsida#Phylogeny)>>

/Castorocauda/ was "scaly", Mike. The scales are on the tail. Ask a mouse about synapsid scales.
