Figure 3

Elemental (Sr, Ba, U and ΣREE) profiles are compared with the CL collagen signal of FK BI RS 1 bone. Outer surface is on the left and the inner part is on the right. Spikes in Sr and Ba profiles at ca. 5600 µm and 9000 µm possibly reflect the presence of post-depositional secondary bone porosity infills by diagenetic minerals or sediment. Note that U and ΣREE are reported in log-scale. Semi-quantitative intensities of the light signal were interpolated from the CL image itself along the LA profile using Icy 2.1.2.0 (icy.bioimageanalysis.org69) and reported as relative intensities (scaled to the maximum value). To obtain a representative averaged signal of the area of interest, data from six equidistant lines were collected. Finally, a LOWESS smoothing filter (span 0.1) was applied to the resulting averaged signal.
