Taxonomy

Coryphodontidae was named by Marsh (1876).

It was assigned to Amblypoda by Flower and Lydekker (1891); to Pantodonta by Hay (1902); to Amblypoda by Gregory (1910); to Amblypodi by Jaekel (1911); to Coryphodontoidea by Simons (1960) and McKenna and Bell (1997); and to Pantodonta by Patterson (1939), Flerow (1957), Carroll (1988), de Muizon and Marshall (1992) and Rose et al. (2012).

Subtaxa

Asiocoryphodon, Coryphodon (syn. Bathmodon, Ectacodon, Metalophodon, Loxolophodon, Manteodon), Eudinoceras (syn. Metacoryphodon), Heterocoryphodon, Hypercoryphodon, Wutucoryphodon

Synonyms
