chert
this is a chert flake,it is debatage or debri from the manufacturing of arrow heads and knives,it could have been used as a small knife,arrow heads and knives are made of chert not flint,flint is harder to knapp for arrow heads and knives,flint is used in gun flints,this flake was found on a prehistoric site in America, the earliest prehistoric site, start at 12000BC (Paleo) the latest prehistoric sites are the Mississippian sites which date around 800AD to 1300AD, in the years past I sufaced hunted prehistoric sites,in Madison,Jersey,Macoupin,Calhoun,Greene,St. Clair counties in Illinois and St.Louis and St.Charles counties in Missouri, I have 35 years exp.in prehistoric North American Archeology and I worked as professional archeologist for 11 years and in the past I have seen thousands of these flakes,if it was used as a scraper it will have use polish on the broad sides of the flake,you could go back to this site and surface hunt the site by walking a grid pattern,when I surfaced hunted I would north and south then east and west,the late prehistoric sites are my favorite site to hunt,on these site you will find pottery chards,pipes,arrow heads,knives,shell beads and some times,but a very rare find,a very rare find is a complete jar made of clay,,any way I hope this has helped and did not cause any confusion,if you have any questions please send me an email,with a photo if possible Thanks!!Dave Hall,Alton,IL.
