Re: T.rex Pubis Boot

By this hypothesis, gracile vs. robust being dimorphisms is the same
question.  I have read that the gracile vs. robust idea does not necessarily
imply dimorphism.  We also don't have a statistically sized population for
T. rex to test this idea with.

I would, however, wonder about the repercussions the allometry idea might
have on Rigby's rex with the abnormally large pubis.
