Bifurcate-stemmed Projectile Points in the Eastern United States

In 1953 it was suggested that bifurcate-stemmed projectile points might serve as a horizon marker in the southwestern United States. Since then material has been reported which indicates that this is also true for the eastern United States. There are two types of bifurcate-stemmed points: a larger form which may be older than 5000B.C.and a smaller form which appears to be more recent
