Re: When carnivores kill other carnivores...
As I understand it, Rauhut's rationale is incorrect because Huene only
conditionally proposed Altispinax for the vertebrae. He said something to
the effect of "If the dorsals are found not to belong to Megalosaurus, they
should be named Altispinax." Conditional naming is apparently not accepted
by the ICZN.

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.
