1 Fig. 2 Blue particles observed embedded within archaeological dental calculus.
Blue particles observed embedded within archaeological dental calculus. (A) Archaeological tooth from individual B78 showing attached dental calculus deposits before sampling. (B) View of blue particles embedded within a large piece of intact dental calculus, as well as a blue particle already freed from dental calculus. (C to I) Multiple blue particles observed following sonication of dental calculus. Note the frequent co-occurrence of associated colorless minerals. Images (B) to (I) are shown to the same scale, as indicated in (I). Credit: C. Warinner (A); M. Tromp and A. Radini (B to I). A. Radini et al.
