Abstract

Equus cedralensis is a small-sized Pleistocene Mexican horse species that has a very similar occlusal pattern and size to those of Haringtonhippus francisci (= Equus francisci), but it can be distinguished from the latter because it is a not stilt-legged equid. We performed multivariate and univariate analyses of metatarsals of stilt- and stout-legged equid species to determine if E. cedralensis was a non-stilt legged horse. Our results indicated that E. cedralensis is a stilt-legged horse and as such, it should be considered a junior synonym of Haringtonhippus francisci, because there is not any other valid autapomorphy that allows it to be recognized. H. francisci had a very broad geographic range during the Pleistocene in North America, from Alaska to southern Mexico.
