These findings were much higher than the endangered artiodactyl populations in Southeast Asia.

There are about 220 artiodactyl species, including many that are of great nutritional, economic, and cultural importance to humans.

They also have a simple stomach, rather than the more complex, ruminant, stomach found in most other Artiodactyl families.

There are also larger artiodactyl species, such as the Cape buffalo, common eland and the giraffe.

The Giraffidae are ruminant artiodactyl mammals that share a common ancestor with deer and bovids.

Molecular studies, however, have shown that the Cetacea descend from the Artiodactyl ancestors, although the precise phylogeny within the order remains uncertain.

Oromerycids are placed in the artiodactyl suborder Tylopoda, which also includes camels and a variable number of extinct families.

Elomeryx is an extinct genus of artiodactyl ungulate, and is among the earliest known anthracotheres.

Both cetaceans and artiodactyl are now classified under the super-order Cetartiodactyla which includes both whales and hippopotamuses.

All cetaceans, including whales, dolphins and porpoises, are descendants of land-living mammals of the Artiodactyl order (even-toed ungulates).

As is implied by their classification under the order Artiodactyla, they are artiodactyls.

Like many other species of Artiodactyla, deer have seven major external scent glands distributed throughout their bodies.

(The other major ungulate order, called Artiodactyla, contains creatures with an even number of toes on each foot.

Order Artiodactyla.

The discovery of this fossil is important as it helped solidify the theory that whales shared a common ancestor with Artiodactyla.

Many are not, however, in support of the hypothesis that Cetacea evolved from within the Artiodactyla.

Agriochoerus and other agriochoerids possessed claws, which is rare within Artiodactyla.

Some groups only have one species that undergoes embryonic diapause, such as the roe deer in the order Artiodactyla.

Order Artiodactyla (cattle and other ungulates)

This branch contains animals classified under the orders Cetacea and Artiodactyla.

Suids belong to the order Artiodactyla, and are generally regarded as the living members of that order most similar to the ancestral form.

This is in contrast to even-toed ungulates, members of the order Artiodactyla, which walk on cloven hooves, or two toes.

The term was coined by merging the name for the two orders, Cetacea and Artiodactyla, into a single word.

The idea that whales evolved from within the Artiodactyla is based on analysis of DNA sequences.

Anoplotheriidae is a prehistorically extinct family of even-toed ungulates (order Artiodactyla).

They are suspected of being closely related to the true ungulate orders Perissodactyla and Artiodactyla.

Tahrs belong to the order Artiodactyla, which denotes an even-toed ungulate mammal.

All scholars agree, however, that the oreodont was an early form of even-toed ungulate, belonging to the order Artiodactyla.

It comprises the Artiodactyla and Perissodactyla.
