Taxonomy

The genus Ponteixites is currently deemed a junior synonym of Rhaeboceras, with most specimens formerly assigned to Ponteixites appearing to be juveniles. The finding of a larger fossil specimen assigned to P. robustus similar to these juvenile remains provides evidence supporting this lumping.
