 Pregnancy complications are poorly represented in the archeological record, despite their importance in contemporary and ancient societies. While we excavated a Byzantine cemetery in Troy, we discovered calcified abscesses among a woman?s remains. Scanning electron microscopy of the tissue revealed ?ghost cells?, resulting from dystrophic calcification, which preserved ancient maternal, fetal and bacterial DNA of a severe infection, likely chorioamnionitis.<
