Systematics
''Comodon'' was originally named ''Phascolodon'' by Simpson (1925) for USNM 2703, a mandible from Quarry 9 in Como Bluff, Wyoming. However, the name ''Phascolodon'' was already in use for a ciliophore described in 1859, and the replacement name ''Comodon'' ("tooth from Como Bluff") was erected by Kretzoi & Kretzoi (2000). Meanwhile, Cifelli & Dykes (2001) coined the replacement name ''Phascolotheridium'' for ''Phascolodon'', unaware of the paper by Kretzoi and Kretzoi (2000).
