Re: Scaly tyrannosaurs; fact or fiction?
Just back from a vacation. This discussion about Tyrannosaurus being or not
being member of clade (_Sinosauropteryx_ + _Passeres_), for which feathery
integument is known, reminded me of an earlier eMail from DinoGeorge.
On Wed, 26 May 1999, DinoGeorge wrote in a discussion about the integumentary
filaments as in Sinosauropteryx:

Am I mistaken or does it really sound like this would put Tyrannosaurus (and
with it any other dinosaur) into a clade for which feathery integument is
known? Any more information permitted for release now or do we have to wait
