FIGURE 1.

The relationship between the wet density of a mineralized tissue and the equatorial diffraction spacing. The upper line refers to the wet tissue; the lower line to the same tissues when dried. The abscissa is the inverse density (Lees et al., 1984a; Lees, 1998). Parameters: d_w = 0.887 + 0.772/ρ (R² = 0.98); d_d = 1.364 − 0.437/ρ (R² = 0.92); d_w = lateral spacing of wet tissue; d_d of dry tissue; and ρ = wet tissue density.
