Mammoth Spring, Arkansas, portable rock art finds identified by Jeff Vincent include known "face on rhombus" and tabular limestone bird sculpture motifs
Jeff Vincent find, Mammoth Spring, Arkansas
Jeff has identified several portable rock art sculpture forms at his site in Mammoth Springs, Arkansas. The "face on rhombus" was first described by German Pleistocene rock art pioneer Ursel Benekendorff whose proto-sculpture and sculpture finds from northern Germany date to ca. 475,000 years before present. Jeff's example here likely also exhibits the "one eye open, one eye closed or missing" motif associated with some of the human face mask art objects of the European Lower and Middle Palaeolithic.
Rhomboid stone forms are recurring at many sites in North America where similar kinds of portable rock art objects are also identified, with archaeologists other than Benekendorff also describing them in the "Old World."
A worked face was also detected on this rhomboid from California and described in an earlier posting on this blog.
