Most terrestrial ungulates use the hoofed tips of their toes to support their body weight while standing or moving. Two other orders of ungulates, Notoungulata and Litopterna, both native to South America, became extinct at the end of the Pleistocene, around 12,000 years ago. The term means, roughly, "being hoofed" or "hoofed animal".
The white rhinoceros is the largest living perissodactyl. Perissodactyla (/ p ə ˌ r ɪ s oʊ ˈ d æ k t ɪ l ə /, from Ancient Greek περισσός, perissós 'odd' and δάκτυλος, dáktylos 'finger, toe' [3]), or odd-toed ungulates, is an order of ungulates.
Ungulates (meaning roughly "hoofed" or "hoofed animal") are several groups of mammals most of which use the tips of their toes, usually hoofed, to sustain their whole bodyweight whilst moving. The main article for this category is ungulate .
Some researchers use "even-toed ungulates" to exclude cetaceans and only include terrestrial artiodactyls, making the term paraphyletic in nature. The roughly 270 land-based even-toed ungulate species include pigs , peccaries , hippopotamuses , antelopes , deer , giraffes , camels , llamas , alpacas , sheep , goats and cattle .
Various artiodactyls, representing all four suborders. Artiodactyla is an order of placental mammals composed of even-toed ungulates – hooved animals which bear weight equally on two of their five toes with the other toes either present, absent, vestigial, or pointing posteriorly – as well as their descendants, the aquatic cetaceans.
Tragulus is a genus of even-toed ungulates in the family Tragulidae that are known as mouse-deer. [1] In Ancient Greek τράγος (tragos) means a male goat, [2] while the Latin diminutive –ulus means 'tiny'.
The two largest groups of South American ungulates, the notoungulates and the litopterns, were the only groups to persist beyond the mid Miocene. Only a few (mostly large) species of notoungulates and litopterns survived until the end-Pleistocene extinction event around 12,000 years ago where they became extinct with most other large mammals in ...
Pan-Euungulata (literally: "all true ungulates"; also known as: Euungulata [sensu lato] [2]) is a clade of placental mammals from grandorder Ferungulata, consisting of the taxon Euungulata [sensu stricto] and all taxa (species) more closely related to it than to any other living species.
