Elemental images of sample S2 obtained by LA-ICPMS. (a) Photomicrographs of the sample, (b) CL image of the collagen distribution, (c) 238U, (d) 137Ba, (e) 88Sr, (f) 175Lu (as REE content proxy). Note that the elemental images are not reported normalized to an internal standard but as raw cps (counts per second). Maps were obtained using a MATLAB 2010a script62.
