Anoplotherium commune skull, National Museum of Natural History, France. The research history of Anoplotherium spans back to 1804 when Georges Cuvier first described the fossils of this extinct artiodactyl and named the genus after describing Palaeotherium, making it one of the first fossil mammal genera to be described as well as having one of the earliest official taxonomic authorities.
The increased extent of extinction mirrors the migration pattern of modern humans: the further away from Africa, the more recently humans inhabited the area, the less time those environments (including its megafauna) had to become accustomed to humans (and vice versa). There are two main hypotheses to explain this extinction:
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.
This interpretation, Hooker explained, means that the localities represented very brief moments of survival of endemic faunas during the Grande Coupure, therefore supporting the idea of a major and rapid faunal extinction and immigration event, including the extinction of Anoplotherium in the event.
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 extinction status of the ivory-billed woodpecker is still up for debate, as ornithologists are mixed on the bird’s existence. A new study claims to have documented the presence of birds with ...
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.
