The four summarized Artiodactyla taxa are divided into ten extant families: [26] The camelids ( Tylopoda ) comprise only one family, Camelidae . It is a species-poor artiodactyl suborder of North American origin [ 27 ] that is well adapted to extreme habitats—the dromedary and Bactrian camels in the Old World deserts and the guanacos , llamas ...
The order Artiodactyla consists of 349 extant species belonging to 132 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 132 genera can be grouped into 23 families; these families are grouped into named suborders and many are further grouped into named clades, and some of these families are subdivided into named subfamilies.
Anthracotheriidae is a paraphyletic family of extinct, hippopotamus-like artiodactyl ungulates related to hippopotamuses and whales.The oldest genus, Elomeryx, first appeared during the middle Eocene in Asia.
The evolution of cetaceans is thought to have begun in the Indian subcontinent from even-toed ungulates (Artiodactyla) 50 million years ago (mya) and to have proceeded over a period of at least 15 million years. [2] Cetaceans are fully aquatic mammals belonging to the order Artiodactyla and branched off from other artiodactyls around 50 mya.
Protoceratidae is an extinct family of herbivorous North American artiodactyls (even-toed ungulates) that lived during the Eocene through Pliocene.While early members of the group were hornless, in later members males developed elaborate cranial ornamentation.
Cainotheriidae is an extinct family of artiodactyls known from the Late Eocene to Middle Miocene of Europe.They are mostly found preserved in karstic deposits.. These animals were small in size, and generally did not exceed 15 centimetres (5.9 in) in height at the shoulders, ranging in size from those of rabbits to tragulids.
