Dicynodon ("two dog-teeth") is a genus ofdicynodonttherapsid that flourished during theUpper Permianperiod. Like all dicynodonts, it was anherbivorous animal. This synapsid was toothless, except for prominent tusks, hence the name. It probably cropped vegetation with a horny beak, much like a tortoise, while the tusks may have been used for digging up roots and tubers.

Many species ofDicynodon have been named, and the genus is considered awastebasket taxon. A 2011 study of the genus found most of the species to represent aparaphyletic grouping, with the only valid members ofDicynodon beingD. lacerticeps andD. huenei.^[1] A 2019 study named a new speciesD. angielczyki, but simultaneously transferredD. huenei to the genusDaptocephalus.^[2]

Dicynodon was a medium-sized and advanced member of the Dicynodont group. It had an average length of 1.2 metres (3.9 ft), although size differed among species. Its fossil remains have been found in sediments of latest Permian age in South Africa and Tanzania.

Thetype species isDicynodon lacerticeps Owen, 1845. A large number of species have since been placed in this genus, some of which turned out to be synonyms of other species, others have been moved to different genera.

Two species ofDicynodon are currently recognized: thetype speciesD. lacerticeps from South Africa and the speciesD. angielczyki from Tanzania. Since the genus was first named, over 160 species have been assigned toDicynodon. A 2011 study of the genus found 11 of these species to be valid, although most are now assigned to other dicynodont genera.^[1] Below is a list of all species that have ever been assigned toDicynodon. Since their naming, most have been considered as synonymous with other dicynodont species. Names in bold are still referable toDicynodon.
