Diademodontidae is an extinct family of Triassic gomphodonts. The best-known genus is Diademodon from South Africa. Titanogomphodon from Namibia may also be a member of Diademodontidae. [1] The Chinese genera Hazhenia and Ordosiodon have also been included in the family, but were more recently identified as baurioid therocephalians. [2] Remains of a diademodontid were reported in the Early-Middle Triassic Fremouw Formation in Antarctica, [3] but that specimen was later referred to the trirachodontid Impidens . [4]
