This species represents the larger end of the prehistoric horse spectrum – it was about the size of a mustang, weighing up to 519 kilograms (1,144 lb).[5] It was a stoutly built animal and resembled the extinct quagga or the modern plains zebra, although it was not a close relative to either of these.
