Horses are odd-toed ungulates, or members of the order Perissodactyla.

Their closest relatives are the other odd-toed ungulates, including horses and rhinoceroses.

According to this, the odd-toed ungulates' closest living relatives are the carnivorans.

The amino acid sequences do not support a connection with perissodactyls (odd-toed ungulates).

Diplacodon is a genus of prehistoric odd-toed ungulates in the family Brontotheriidae.

Eomoropidae is a family of odd-toed ungulates, a group which also includes horses, rhinoceroses, and tapirs.

Odd-toed ungulates include the horse, tapirs, and rhinoceroses.

Hippomorpha are odd-toed ungulates that are, today, fast runners with long legs and one toe per foot.

The odd-toed ungulates, such as the horse, use a single third toe for weight-bearing and have significantly reduced metacarpals.

Perissodactyls are the order of odd-toed ungulates, including horses, rhinos, tapirs and other extinct forms.

Based on morphology, odd-toed ungulates were long thought to form a clade with even-toed ungulates.

Rhinoceroses are odd-toed ungulates with horns made of keratin, the same type of protein composing hair.

Order Perissodactyla (odd-toed ungulates)

Bats are closer to Carnivora and odd-toed ungulates than to primates and Dermoptera (colugos).

The odd-toed ungulates have been among the most important herbivorous mammals; at times, they have been the dominant herbivores in many ecosystems.

Odd-toed Ungulates (Perissodactyla)

Horses and other equids are odd-toed ungulates of the order Perissodactyla, a group of mammals that was dominant during the Tertiary period.

Order Perissodactyla: odd-toed ungulates, including horses, donkeys, zebras, tapirs, and rhinoceroses (cosmopolitan)

For example, hyraxes in his Paenungulata had some characteristics suggesting they might be connected to the odd-toed ungulates (Perissodactyla, such as horses and rhinos).

For many millions of years, hyraxes were the primary terrestrial herbivore in Africa, just as odd-toed ungulates were in North America.

Genetic studies have now placed bats in the superorder Laurasiatheria, along with carnivorans, pangolins, odd-toed ungulates, even-toed ungulates, and cetaceans.

'Rhinoceros' (), often colloquially abbreviated 'rhino', is a name used to group five extant species of odd-toed ungulates in the family (biology) 'Rhinocerotidae'.

Zooamata is a proposed clade of mammals consisting of Ferae (carnivores and pangolins) and Perissodactyla (odd-toed ungulates).

Horses are odd-toed ungulates, or members of the order Perissodactyla.

These all belong to the Perissodactyla.

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

Order Perissodactyla.

Ferae, Perissodactyla, and Chiroptera together has been called Pegasoferae.

It is part of the cohort Ferae, and is possibly a sister taxon to the Perissodactyla.

Horses belong to the order Perissodactyla, or odd-toed ungulates條arge, herbivorous animals with an odd number of toes on each foot.

It comprises the Artiodactyla and Perissodactyla.

Ancylopoda is a group of browsing, herbivorous, mammals in the Perissodactyla that show long, curved and cleft claws.

New Remains of Paraelasmotherium (Perissodactyla.

Equidae belongs to the order Perissodactyla, which includes the extant tapirs and rhinoceros, and still more fossils.

A conflicting proposal links the Perissodactyla and Cetartiodactyla in a clade named Euungulata.

Chalicotherium, like many members of Perissodactyla, was adapted to browsing, though uniquely adapted to do so among its ungulate relatives.

The phylogeny of the Rhinocerotoidea (Mammalia, Perissodactyla).

The Perissodactyla and Artiodactyla is the largest portion of ungulates, and also comprise the majority of large land mammals.

Lambdotheriidae is an extinct family of the Perissodactyla (odd-toed ungulate) order (that is, browsing and grazing animals).

Suborder Hyracoidea (sister taxon of Perissodactyla?)

A rhinoceros (also called a rhino for short) is any of five living species of mammals in the family Rhinocerotidae, of the order Perissodactyla.

Variation, sexual dimorphism, and social structure in the early Eocene horse Hyracotherium (Mammalia, Perissodactyla).

Horses and other equids are odd-toed ungulates of the order Perissodactyla, a group of mammals that was dominant during the Tertiary period.

Order Perissodactyla: odd-toed ungulates, including horses, donkeys, zebras, tapirs, and rhinoceroses (cosmopolitan)

Phylogenetic Systematics of the Brontotheriidae (Mammalia, Perissodactyla).

For example, hyraxes in his Paenungulata had some characteristics suggesting they might be connected to the odd-toed ungulates (Perissodactyla, such as horses and rhinos).

There is still uncertainty regarding the phylogenetic tree for extant Laurasiatherians, primarily due to disagreement about the placement of Chiroptera and Perissodactyla.

Brontotheriidae, also called Titanotheriidae, is a family of extinct mammals belonging to the order Perissodactyla, the order that includes horses, rhinoceroses, and tapirs.
