Photograph from the mid-1870s of a pile of American Bison skulls waiting to be ground for fertilizer. Bison were hunted almost to extinction in the 19th century and were reduced to a few hundred head by the mid-1880s, from which all the present day's managed herds are descended. The commercial take arguably was anywhere from 2,000 to 100,000 animals per day, though there are no statistics available.
