several recent posts regarding artifacts & their identificaton prompted me to dig this specimen out of moth balls: it's both artifact & fossil; the tip section of a chipped stone spear or knifepoint, with a little surprise. The planispiral coiled gastropod preserved in the marine chert or flint probably contributed to it's fracture. It would have been a great artifact had it been complete;only now it's been relegated to "conversation piece". Hope you find it interesting.
