Stones at 33GU218
|Incision marks, cut with a hard
sharp-edged stone and V-profile in cross-section, are an
increasingly recognized hallmark of human agency in artifacts
worldwide, found on artifacts dating from the Lower Paleolithic
to as recently as the Late Archaic Period in North
America. Prior to their recognition here at 33GU218 they
were observed (not for the first time) and described at the Gault
Site in Texas.
|This limestone bird figure from
33GU218 with a
quasi-anthropomorphic face displays the distinctive V-profile incision marks characteristic of many artifacts at
the site. Dr. Roy
Mapes, professor of geology at Ohio University, and Dr.
Eric Law, professor of geology at Muskingum University, have identified
the deep and curved cuts in this stone as artificial.
This is also one of several pieces microscopically examined by rock art
expert Dr. Arsen
Faradzhev during a site visit in April 2005 and determined to be
the product of human workmanship.
