Re: Dinosaur Genera List corrections #98

    Bakker had a cast of the skull and the left lower jaw with him at
DinoFest 1998.  I was there when he first showed the skull to Jack McIntosh
and Dong Zhiming.  (In fact, I was holding the jaw for him while he was
showing the braincase to Jack).

    Jack McIntosh's INITIAL view was that the braincase was _significantly_
different than _Apatosaurus_.  Bakker's initial idea was to resurrect
_Brontosaurus_ based on this reconstructed skull  (due to be so much
different than _Apatosaurus_).

    One cautionary note, the skull was reconstructed using a wax casting of
the original, which was then stretched to what was considered the proper
