What did buffalo look like in the old days?

In the old days, particularly before significant European settlement, buffalo, or American bison, roamed the North American plains in massive herds. They had long, shaggy coats that provided insulation against harsh weather, with males typically being larger and more robust than females. Their large heads featured a pronounced hump and sharp, curved horns. This iconic image of the buffalo symbolizes the vast wilderness and rich ecosystems of the American frontier.
