Question: Which genus, Bismarckia or Adonis, if either, contains more species ?
Sentence (from "Langeronyx"): "R. brodiei" was first described and named by Michael Benton in 1990, but its redescription by Martín D. Ezcurra, Felipe Montefeltro and Richard J. Butler in 2016 recovered it as more closely related to the more advance hyperodapedontine than to the type species of "Rhynchosaurus" and thus it was moved to its own genus.
Relevant evidence: No
