Re: Why Thulborn's ideas on dinosaur polyphyly are wrong

for 1970's dinosaur polyphyly proposals (and BAND proposals), Thulborn never

This is something that mystifies me. What's the use in chipping at the
consensus if you don't have an alternative to express? If we were to
accept, say, that the sister-group relationship between saurischians
and ornithischians is poorly supported, we'd still think they're
sisters till he presents a better supported arrangement.
Why can't you be a non-conformist just like everybody else?
