Missouri plaquette depicting a human head profile looking left, crested by a winged bird, found in context of Levallois technology lithic reduction

Keith Stamper identification of human head profile, one of several, he has found among flaked tools in a small area of his yard, St. Peters, Missouri, near the Mississippi River.

Interpreted by Ken Johnston as a plaquette depicting a human head profile looking left, crested by a bird head with a wing feature in relief. This motif has been described by figure stone researcher Alan Day at Ohio site 33GU218.

It appears 3 flakes were removed to create the brow and eyes of the human, which also finishes the bird head form. The stone element in the lower right may be interpreted alternately as hair on the human head or as the bird's wing.
This stone in its own might not be interpreted as a possible artifact. However, Keith Stamper has identified other apparently worked rocks with visual properties like other objects seen on this blog, as well as many stone tools all found in direct context with the suspected art.

The context suggests this is a work of very subtle sculpture relief rather than Keith's imagination. Keith Stamper identified this possible art piece as a human facial profile looking right, with a kind of swept back hair feature on the upper left edge.

Rock likeness to a human head with a prominent nose facing right, in the elongated style described by R. Dale Guthrie and illustrated in his "human to animal" gradient of head depictions in Paleolithic art.

Archaeologists searching for evidence of early Americans need to be looking for technologies which differ from those they are familiar with from the 13,000 BP to present time frame. And maybe they should be looking toward Europe as well as Asia. There is no official recognition of American Levallois technology despite amateurs like Rick Doninger presenting hundreds of examples and every stage of core and flake reduction possible. It has not been described by any archaeologists most likely because they do not know how to recognize it as a discrete set of technologies separate from the most common artifacts they are familiar with (Mode 4 technology). Mode 3 technology persisted until the 19th century in places like Tasmania and it is possible it was brought to North America as well.
