These 1984--1985 Ohio River bank finds are from an eroding midden, a site that was a mix of Adena and Hopewell--and a smattering of Riverton Culture (Late Archaic into Woodland). The midden was thick enough that several hundred years worth of 'house debris', firepits, flintchips and broken hammerstones could indicate either of the two major components (Riverton peoples tended to build shell 'mains' for their trashpits, so I kind of rule them out as the source of these tools). Remember, you didn't have plastic, so you made tools out of the most common raw material you had--animal bone (or bird as in the case of the 3&3/8" bird (Turkey?) legbone that became a hairpin--a neat piece in and of itself. The two cut-off antlers I'm guessing were some sort of flintknapping tools--there had to be some reason they went to the trouble of cutting them free. The fire blackened antler beam (2&5/16") had extensive carving on both ends--frankly any guess we'd make has a 50% chance of being correct. The small perforator was part of a turtle shell if I'm correct--thin. There were some fragments of other awls collected that day, but so broken, so mineralized it's hard to recognize what they were--today, the river eroded the midden, what site was there is long gone.
