Darren et al -

        The reference to which you're referring is:

Chatterjee, S.  (1991).  "Cranial Anatomy and relationships of a new
Triassic bird from Texas," _Philosophical
        Transactions of the Royal Society of London Series B_  332(1265):

        Yes, the second "half" of the paper was, is, and will be out later
this year -- the Royal Society's been sitting on it; it's in that nebulous
"it'll be out in a couple months" stage for almost a year now.  I wonder if
they're having second thoughts, or if they're really that backed up...  ;-)

        George stated in his _Mesozoic Meanderings #2_ that he thought
_Protoavis_ was best suited as a theropod, although one with a very
bird-like skull.  This, of course, fits in nicely with his theory that
birds didn't descend from theropods -- theropods descended from birds,
which, in turn, descended from some mildly bird-like "thecodonts" like
_Cosesaurus_, _Longisquama_, and _Megalancosaurus_.  His assertion, for
anyone who hasn't read his article in _Omni_, is that the original
dinosaurs spring off of the lineage of thecodonts that were evolving into
birds.  This, in his eyes, is why many theropods have bird-like traits --
because they inherited them from bird-like ancestors.  He never quite
bothered with the question of why all the theropods with bird-like traits
are _not_ the Triassic ones, like _Coelophysis_!  8-)
