considered Tylopoda could be confirmed to belong to this suborder (and a few refuted), the delimitation of this group is still very much disputed despite (or because of) an extensive fossil record. The taxa currently assigned (with some reliability) to Tylopoda are: Basal and incertae sedis Genus †Gobiohyus? Family †Homacodontidae Superfamily †Anoplotherioidea Family †Anoplotheriidae Family †Cainotheriidae Family †Dacrytheriidae Superfamily Cameloidea Family †Oromerycidae Family Camelidae Superfamily †Merycoidodontoidea (=Oreodontoidea) Family †"Agriochoeridae" (paraphyletic) Family †Merycoidodontidae Superfamily †Xiphodontoidea Family †Xiphodontidae Disputed Tylopoda Several additional prehistoric (cet)artiodactyl taxa are sometimes assigned to the Tylopoda, but other authors consider them incertae sedis or basal lineages among the (Cet)artiodactyla: Family †Antiacodontidae Family †Choeropotamidae (= Haplobunodontidae) Family †"Diacodexeidae" (paraphyletic) Family †Leptochoeridae The Cebochoeridae and Protoceratidae, on the other hand, are prehistoric families that were occasionally placed within Tylopoda in the past, but are now considered more closely related to cetaceans and ruminants respectively than to camels.
