AFAIK, this species has not been officially named - and a mention in a
dissertation doesn't qualify.  Therefore, it may be a good idea to avoid
using the name 'Allosaurus jimmadseni' to avoid any more confusion.  There
are already a few theropod _nomina nuda_ from the Morrison floating around
in the ether - remember "Brontoraptor", and "Madsenius" before that - and
these have already caused their fair share of confusion.

[Besides, some folks get a little unhappy seeing non-officially-sanctioned
names disseminated over the web.  I should know - I've been guilty of it
once or twice in the past. :-(   ]
