This sculpture found by David Boies near Austin, Texas, is yet another example of a recurring form from portable rock art bearing sites which have been featured on this blog. This one helps confirm this PAC-MAN like form as a broad formal motif which must have had a cultural significance to the people who made and used them. They have been described from Oregon, Tennessee and Mississippi- and now Texas.
The subject of stone toys has been raised here before and its seems possible these simple heads could have used for child play or puppetry. David Boies noted this figure's resemblance to a frog.
The flake removal at left and the mouth at right indicate this is an artifact and not a natural coincidence. Several individual stone removal points with the same or similar patination are highly unlikely on a natural rock. Natural scars on stones have differing patinas because they are so spread out in time.
