Well, he was following Paul's lead. In PDW Paul named a new species of
_Acrocanthosaurus_ (_A. altispinax_) for the spines; Olshevsky just
moved it to its own genus.
This sounds questionable to me, though. If _Megalosaurus dunkeri_ is
just the tooth, then either _A. dunkeri_ is the type species and the
tooth is the holotype of _Altispinax_, or "Altispinax" has never been
given a type species, and is therefore not an available name.
Etymology does not guide taxonomic rules.
