Folsom Discovery The discovery of this spear point stuck between the ribs of an ancient bison near Folsom, New Mexico, revolutionized our understanding of ancient Americans. Since the bison was known to have been extinct for about 10,000 years, ancient Americans must have been hunting them at least 10,000 years ago. This discovery prompted the search for more human artifacts, such as spear points, that proved humans resided in America for thousands of years before the extinction of the ancient bison.
