<<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.
