A very large blade,3&13/16" by 1&5/8", yet THIN, only 5/16" max thickness hornstone Turkey Tail, Gibson county, southwest Indiana, Wabash River area. The stem isn't a snap base, rather it's what was the bottom edge of a very large 'slab'(flake) of Hornstone. When the Late Archaic knapper fashioned as large of a blade as possible there simply wasn't enough flint to form a fully "V" pointed Harrison-type Turkey Tail stem--you can see where he angle-cut the sides of the short stem. Those angle cuts and the overall thinness are the two major reason this isn't an Adena, it's slightly earlier, a Harrison Turkey Tail. One note--that upper blade notch is not 'simple damage', it's a feature incorporated into the blade use--not big enough to be a shaft scraper, , but rounded enough that it had more than a scraping function. Did they use these small indentions for bone awls, that's something I've considered--or, was the notch some help in carving up game; I've heard that explanation, too.
