3D Maps of Mineral Composition and Hydroxyapatite Orientation in Fossil Bone Samples Obtained by X-ray Diffraction Computed Tomography

The data consists of reconstructed XRD-CT tomograms from two fossil samples: A tibia of Discosauriscus austriacus and a humerus of Eusthenopteron foordi. For the tibia of Discosauriscus austriacus, the data has been reconstructed using a single Bragg peak corresponding to hydroxyapatite. For the humerus of Eusthenopteron foordi, the measured XRD-CT data has been separately reconstructed using three separate datasets and Bragg peaks corresponding to the minerals hydroxyapatite, barite, calcite and quartz.

For further details regarding samples, measurements and data analysis, see article and supplementary information.
