I found this object in a river in Russell Pa while hunting for artifacts, it is heavy enough that if it is bone it is fossilized. It has a tendon like piece in one of the sockets about 1.5" long(see image 0004, top,someone was scratching around hence the discoloration), the part that got me going is a piece of flint protruding from one of the faces,see top of photo "flint". Possible projectile point? What should I do with tis item? Thanks!
