This flint tool from my finds site has some ape like faces, two of the faces can be seen at each end of the tool, front on, but only showing one side, something noted on a few finds on this blog. The face on the larger edge looks gorilla like and on the smaller edge sub human. The outside larger edge also shows a face profile on both sides of the blade tool. Many retouch flake removal scars can be seen on this piece of portable rock art, the black material is likely tar or resin.
