CB E21-105 spatulate bone tool photographs and illustration

(A, B, and D)Show somewhat wavy, rather than straight striations, due to the unevenness of retouched lithic edges and lateral movement of the lithic edge against the bone blank.

(C) Is an example of short, deep, non-parallel striations restricted to limited areas of a bone tool that were interpreted as resulting from use. (A and B) show examples of sheen and polish from use and restricted to the sides of the piece.

(D) Shows what are interpreted as manufacture marks on the body of the tool, and the lack of sheen and polish on the body away from the end and sides. (A–D) are microscope photographs with 1 cm scale.

(E–H) Illustrates both sub-parallel shaping marks covering the extent of the surface and short, irregular marks from use. Yellow areas on F and H represent the lightly burned and darkened area at the tip of this bone tool, where polish and sheen from use are frequent. Dotted outlines on (F and H) represent the extent of polish.(E–H) illustrated by J. N. Cerasoni.
