Irritator challengeri

[John Schneiderman <dino@revelation.unomaha.edu>]

I've recently reviewed the article on Irritator and have a couple of 
questions.

Was this skull material compared against _Baryonyx walkeri_ or 
_Elaphrosaurus bambergi_?

Was skull compared against other Pterodactyloidea from the Cretaceous of 
South America?

It seems that the nasal is about midway up the snout (as in Spinosaurids 
and some Pterosaurs) and the lower jaw and cranial crest seems similar to 
some of the larger Pterodactyloid forms.
