  Actually, Paul revised this. In 1988, he used the genus *Altispinax* as
a junior synonym of *Acrocanthosaurus* and coined the species name *A.
altispinax*; as a result of this, he created a species name for the genus,
given the nature of referral, assigned a type, and described it, using the
earlier figures in citation, prior to George's coining of *Becklespinax*.

  Paul is the first to support the name *Altispinax altispinax*, but I
think George has a different issue that makes this even more convoluted.

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
