The archive contains data from the semiquantitative elemental analysis of petrographic slides A1i, B2, B5i and C4 belonging to fossil bones of specimen MPMA 62-0010-02. The data include two compilations, one of point readings on the slides and one of elemental mapping of delineated regions. In addition, high-resolution SEM images are included, most of which have their locations identified in the compilations. Analysis was performed in a JEOL JSM-IT500HR scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS), both manufactured by JEOL. Electron beam energy was maintained at 20kV and current adjusted between STD-60 and STD-80. The whole procedure was performed at the Scanning Electron Microscopy and Spectroscopy Laboratory, Institute of Geosciences (Unicamp).
