Systematics

Comodon was originally named Phascolodon by Simpson (1925) for USNM 2703, a mandible from Quarry 9 in Como Bluff, Wyoming.[2] 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).[3] Meanwhile, Cifelli & Dykes (2001) coined the replacement name Phascolotheridium for Phascolodon, unaware of the paper by Kretzoi and Kretzoi (2000).[4][5]
