Optical microscope (top) and CL (bottom) images of investigated archeological faunal bone samples with known age and provenance (Table 1): (a,d) sample S37 (5 × magnification, outer surface is on the top and the inner part is down), (b,e) sample S40 (1.25 × magnification, outer surface is on the top and the inner part is down), (c,f) sample S2 (1.25 × magnification, inner surface is on the top and the outer part is down), (g,j) sample RSS1 (1.25 × magnification, inner surface is on the top and the outer part is down), (h,k) sample RSS2 (1.25 × magnification, inner surface is on the top and the outer part is down), (i,l) sample RB38 (1.25 × magnification, inner surface is on the top and the outer part is down). LA–ICP–MS points of analysis are showed in CL images placed in “high” (orange) and “low” (green) collagen content areas.
