Middle Archaic Period, 8000-5000 B.C. Auglaize County, Ohio length 4 in. This artifact is made from highly banded green slate. The deep notches resemble the notches on a highly developed Notched Butterfly Bannerstone. In his book, The Archaic Bannerstone, David Lutz notes this trait as a final stage in the development of the Notched Ovate form. This bannerstone has a long and well-documented history. When Byron Knoblock pictured it in his Bannerstone book it was in the collection of F.P. Hills of Delaware, Ohio. It then passed into the A.T. Wehrle collection at Newark, Ohio and then to the Fred Bartol collection at Warsaw, Indiana. When Mr. Bartol was ill and near the end of his life he called Art Gerber and offered him a few fine slate artifacts to remember him by. This was one of those pieces (Lutz, David, L., The Archaic Bannerstone. 2000: 282). Collection History:Gerber Collection Number: AG.B37 F.P. Hills Collection, Delaware, OhioA.T.
