Fig. 3 — Chop marks, cortical scars, and chipped marks on the anterior (C and G) and posterior (A, B, D, E, and F) surface of metapodial shafts. Note the short and slight chop marks combined with flat incisions/sawing marks in (F) and the inclination angle in the mark section almost parallel to the bone on posterior surfaces of metapodials in (A), (F), and (G). Experimental bones in the image are labeled as “EXP” followed by the abbreviation of scenario (SC 1 or SC 2) and exposure week. The 3D images and details were generated by a KH-8700 3D digital microscope. Photo credits: R. Blasco.
