The National Animal Identification System covers most livestock species, including cattle, poultry, horses, donkeys, mules, sheep, goats and swine, as well as bison, deer, elk, llamas, alpacas and even some fish species, under the heading of aquaculture. Household pets such as cats and dogs are not included. [8]
This was confirmed in a genetic study done in 2017, which subsumed all the specimens into the species E. francisci which was placed outside all extant horse species in the new genus Haringtonhippus [19], although its placement as a separate genus was subsequently questioned. [20] A separate genus of horse, Hippidion existed in South America. [21]
Haringtonhippus is named after Charles Richard Harington. [3] It was originally described as a new Equus species, E. francisci, in 1915. [1] Dalquest (1979) considered Equus tau Owen, 1869, described from teeth in Mexico, a senior synonym of E. francisci, [7] while Equus quinni and E. arrelanoi were synonymized with E. francisci by Winans (1989).

Horses and other equids are odd-toed ungulates of the order Perissodactyla, a group of mammals dominant during the Tertiary period. In the past, this order contained 14 families, but only three—Equidae (the horse and related species), Tapiridae (the tapir), and Rhinocerotidae (the rhinoceroses)—have survived to the present day.

Equidae (commonly known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, asses, and zebras, and many other species known only from fossils. The family evolved more than 50 million years ago, in the Eocene epoch, from a small, multi-toed ungulate into larger, single-toed animals.
Adult horse flies can be found in July and August. Males of this species feed on plant juices, while female are bloodsuckers. The females have a high fecundity. They can lay about 500 eggs at an oviposition. The larvae pass through 10–13 instars and the full life-cycle lasts 3–5 years. This horsefly may cause appreciable damages on stock farms.
Rhinocerotidae contains five species of rhinoceroses split into four genera, Tapiridae contains four species of tapir in a single genus, and Equidae contains nine species in a single genus, including horses, donkeys, and zebras. Over 75 extinct Perissodactyla species have been discovered, though due to ongoing research and discoveries the exact ...
