Interesting!  Anybody have a ref on this?  What about all the various
extinct crocodiloformes? 

What about phytosaurs?

Anybody?


My apologies if this was discussed on list already, but how about Scipionyx? 
(list archive references?) (I just did a quick archive search & didn't find
anything ...)

What about variations in modern birds? What about extinct birds?

Heck, I guess what I'm asking is, "anybody know of a Survey of
Pneumatization?"
