My current slave driving employers, Western Paleontological Labs have a
juvenile ceratosaur that is being discribed By Dan Chure, Brooks Britt and
heaven alone knows who else. Scott Samson came down from The U of U to see
it a few months back. I don't know when they're going to publish, but the
skull was reconstructed this week and it's beautiful. There is about 75
percent original material., and a fully reconstructed cast will be presented
at The North American Museum of Ancient Life's First opening, July 1st.,
2,000. (Shameless Plug.)
