Subject: Protoavis Material, Episode II

Many thanks to everyone who responded to my question about _Protoavis_ material.  Now for episode two.
 
Back in December of 1999, HP Holtz posted the following information to the Dinosaur Mailing List (entire message available at http://www.cmnh.org/fun/dinosaur-archive/1999Dec/msg00137.html):
 
<<<I do not recall anyone setting down in print (in the technical literature)an element-by-element, taxon-by-taxon description of the _Protoavis_ material, but opinions voiced by various authors seem to converge on several points:
The braincase is probably theropodan;
The manus is probably rauisuchian (and Sereno 1997 suggests it is a foot, not a hand);
Some of the limb elements are some non-archosaurian diapsid (can't recall what was the suggestion: prolacertiform, maybe?).>>>
 
My question is, has anything changed since HP Holtz's post?  Has any of the information he posted been called into question in the intervening time?  Can anything now be added to his list?
 
Any new thoughts on what type of theropod the braincase belonged to?  Coelophysoid?  Herrerasaurid?
 
And also, what WAS the suggestion for the identity of "some of the limb elements"?  WAS it prolacertiform?  And which limb elements in particular?
 
Thanks a lot.  Peace out,
-Grant Harding
 
 
 
Still,...one would think that if Protoavis were a random grouping of several animal parts, there would be at least some redundant parts,...(like extra arm bones, foot bones, different types of vertebrae). I believe George O. already pointed this out....and a good point it is. Statistically, the more animal types it is supposedly composed of, the more redundancy of parts you would expect, ....(unless you are implying it was a skillfully put together "Piltdown type" of hoax).
