Summary of urine salt input trends in the sediments of AH (66). (A) Mean soluble salt concentrations in the archaeological levels and in the natural alluvium at the base of the mound. Sodium [Na⁺], chlorine [Cl⁻], and nitrate [NO₃⁻] are given in moles × 1,000 kg⁻¹. (B) Model-predicted densities of organisms (per m²) required to produce urine-related [Na⁺], [Cl⁻], and [NO₃⁻] values, averaged by level using variable sedimentation rates based on ¹⁴C-dated level boundaries. (C) Changes in caprine number of identified specimens (NISP) as percent of total taxon-specific NISP.
