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.
