Fig. 10. Thin section of the tibia GPIT/RE/3724 of ornithopod dinosaur Dysalotosaurus lettowvorbecki Pompeckj, 1920, from Kimmeridgian, Late Jurassic of Tendaguru, Tanzania, cut within the lower third of the long bone shaft. Most of the marrow cavity is filled by fine, calcareous marl. Note that the top of the cavity has been filled subsequently by calcite crystals, which indicates that the bone was embedded in the substrate as oriented as in this image.
