Onager a subspecies of the onager as "E. hemionus kiang", but recent molecular studies indicate it to be a distinct species, having diverged from the closest relative of the Mongolian wild ass's ancestor less than 500,000 years ago. Widely five recognized subspecies of the onager include: A sixth possible subspecies, the Gobi khulan ("E. h. luteus", also called the "chigetai" or "dziggetai") has been proposed, but may be synonymous with "E. h. hemionus".

Animal track Animal track An animal track is an imprint left behind in soil, snow, or mud, or on some other ground surface, by an animal walking across it.

Books are commonly used to identify animal tracks, which may look different based on the weight of the particular animal and the type of strata in which they are made. Tracks can be fossilized over millions of years. It is for this reason we are able to see fossilized dinosaur tracks in
