Paul 1988 mentions the combination _Altipinax altispinax_ nowhere -- Rauhut was
the first to do that.

Paul notes that the tooth taxon (_dunkeri_) *may* be synonymous with the spine
taxon (_altispinax_), but may not.
He also states that "von Huene's generic name [Altispinax] has never been
validated." (Does this ignore Kuhn 1933?)
