Skull art for theropods

["Walt Owen" <wowen@discover.net>]

Hello, all!

I am currently looking for technical drawings of theropod skulls for a class 
project.  I need clear drawings in accessible texts (Things I can pick up from 
bookstores, if possible), so my students can compare and contrast.  I already 
use Greg Paul's book _Predatory Dinosaurs..._ (Actually I have had several 
copies.  The kids use them so much they have fallen apart) and I was looking 
for more examples.

 I am interested in 3/4 profile, full profile, front and top views, 
Tyrannosaurs and Allosaurs primarily, but all theropods are useful to me.

If anybody can suggest sources for me, I would greatly appreciate it!

Thanks!

Walt
