I was trying to be more specific.  I am saying I do not think he
good at determining *phylogenetic relationships*.  Just that, no
more. On anatomy in general he is probably competent enough. He
just can't seem to distinguish a true synapomorphy froma convergence.

It seems to me that the conclusion that we should be drawing is that
poposaurids were generally *ecologically* convergent with the more
higly derived theropods.
