A Johnson County, Illinois, find, prov. inked-on by the last owner (or finder, I didn't ask). There is a very light flute on one face, but the 'impression' I have is that the Paleo was a salvage of a much longer Clovis--they made a new base on what was a broken tip and couldn't build a 'platform' for a flute strike which would thin the medial ridge--maybe the Paleo hunter didn't try, figuring the piece would shatter. Generally, a Clovis would be much longer than the 1&7/16" this dart measures, but like any 10,000 year old artifact we can read-in something WE think that an ancient hunter would shake their heat at--make sense? The width is 7/8", the max thickness goes slightly over 1/4"--NOT thick, but the thickness, the medial ridge extends down to the hafting area to where the final 5/16" where the base is thinned (and ground)--that "ridge" is why I think this was a salvage, not the original length. Every detail is guaranteed authentic, period. The flint looks more like Indiana hornstone than Cobden, the Illinois hornstone you'd expect in western Illinois, but there are far more grades of flint than just the 'banded' Cobden that's more common. Shipping is $9.00, checks or M.O>s are welcomed. Sorry, I do not use paypal-type services--Roy A.
