Taxonomy
There are currently three species belonging to this genus:
- Rhaeboceras burkholderi (Cobban, 1987)
- Rhaeboceras cedarense (Grier and Grier, 2015)
- Rhaeboceras robustus (Warren, 1934)
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.[2]
