Here the word Ornithomimidorum goes with the additional nouns "gen. a" and
"gen. b," to yield the abbreviation phrases "Ornithomimidorum gen. a" and
"Ornithomimidorum gen. b." These are simply latinizations of "ornithomimid
genus a" and "ornithomimid genus b," terms that Huene invented to stand for
generic names he didn't feel like creating. "Ornithomimidorum" is simply the
latinized genitive plural of "ornithomimid."
Specifically, Huene transferred Megalosaurus lonzeensis to Ornithomimidae as
Ornithomimidorum gen. a lonzeensis, and Megalosaurus bredai to Ornithomimidae
as Ornithomimidorum gen. b bredai. Later Kuhn transferred Ornithomimidorum
gen. a to Ornithomimus itself, as Ornithomimus lonzeensis (where it
languishes even now, as far as I know), and Huene referred Ornithomimidorum
gen. b bredai to the new genus Betasuchus as Betasuchus bredai. The "beta" of
Betasuchus refers, I believe, to the "genus b" of Ornithomimidorum gen. b.
The material is probably indeterminate, but may be worth looking at. I dimly
recall a recent paper by Buffetaut(?) that comments on the status of
Betasuchus as a possible abelisaurid.
These kinds of constructions have no scientific standing and are, I believe,
presently excluded from scientific nomenclature under a provision of the Code
that deals with serialized taxon names.
