Sivalhippus
Sivalhippus is an extinct genus of horse that lived in Africa and the Indian subcontinent during the late Miocene. Paleobiology. Like other extinct horses, the habitat (biome) of "Sivalhippus" consisted of non-forested, grassy plains, shortgrass prairie or steppes. Although "Cremohipparion"-like horses have been found in younger deposits of the Sivalik Hills, they tend to be much rarer. Taxonomy. This genus has a convoluted taxonomic history. After being described as a distinct genus, the holotype of "Sivalhippus theobaldi", GSI 153, was later referred to "Hippotherium" and then "Hipparion", as was the case with most other hipparionin species for most  of the 20th century. Later, Skinner and MacFadden (1977), MacFadden and Bakr (1979), and MacFadden and Woodburne (1982) reassigned "Sivalhippus" to the North American genus "Cormohipparion" based on similarities with specimens of that genus. However, a 2013 review of Sivalik hipparionins found "Sivalihippus" to be distinct from "Cormohipparion" and more closely related to "Proboscidipparion" and "Cremohipparion" than to "Cormohipparion".
