File:Megaloceros (Giant Elk) Jaw Fossil.jpg|
Note the row of large grinding teeth. This jaw section would have been from the left upper side of the head. The lower part of the eye socket is also clearly visible.
Specimens of deer (Odocoileus virginianus), caribou (Rangifer tarandus), and elk (Cervus elaphus). Have been found in deposits that are late Pleistocene or early Holocene. Two fairly complete elk skeletons from Ohio have been radiocarbon dated to about 9,000 years old, suggesting that elk, which survived in Ohio until historic times, may have been an early migrant into the state after extinction of the megafauna.
