Superorder Merocheta

Merocheta is a proposed superorder within placental mammals that groups together large-bodied ungulates, particularly those in the orders Perissodactyla and Artiodactyla. The name “Merocheta” has been used in certain historical or alternative mammalian classification systems to reflect evolutionary relationships among hoofed mammals.

Members associated with Merocheta include odd-toed ungulates such as horses, rhinoceroses, and tapirs (order Perissodactyla), as well as even-toed ungulates like deer, cattle, pigs, camels, and hippopotamuses (order Artiodactyla). These mammals are primarily herbivorous and are characterized by adaptations for terrestrial locomotion, including well-developed limbs and specialized hooves.

Most species traditionally grouped under this concept are medium to large in size and occupy diverse habitats ranging from grasslands and savannas to forests, wetlands, and mountainous regions. They play essential ecological roles as large herbivores, shaping vegetation structure and serving as prey for large carnivores.

It is important to note that Merocheta is not widely used in modern mammalian taxonomy, as contemporary classifications are based on molecular phylogenetics and recognize different higher-level groupings within placental mammals.
