Fig. 13 in Research history, taphonomy, and age structure of a mass accumulation of the ornithopod dinosaur Dysalotosaurus lettowvorbecki from the Upper Jurassic of Tanzania
Fig. 13. Sketches by Ina or Hans Reck of articulated partial skeletons found in 1912. According to Table 2, both specimens were found in the uppermost bonebed 4. A. The German notes on the sketch tell correspondingly that this skeleton was lying with its long-axis in W-E-orientation, that it was only missing the lower part of the foot and parts of the tail, and that the skull was broken and removed separately. The skull was catalogued as WJ9000 and the postcranial skeleton as WJ5790-5820 (the latter were lost in Hamburg during WWII) which can be found in H. Reck's catalogue. The sketch was drawn on the 28th of September. B. The arrow points to a series of at least 20 articulated vertebrae. Another vertebral series, next to it on the right, is still partly covered in clay. Right next to the latter one can see the word Kicwa! (Swahili for skull). At the bottom of the image are noted teeth and a jawbone. According to the note in the lower left corner, the illustrator was unsure whether there were one small vertebral series or two. The numbers WJ9009-9023 are also present in H. Reck's catalogue. The sketch is dated 2nd of October 1912 (Pal. Mus SII, TendaguruExpedition 9.1, Archive of the Historical Division of the MfN).
Fig. 10 in Research history, taphonomy, and age structure of a mass accumulation of the ornithopod dinosaur Dysalotosaurus lettowvorbecki from the Upper Jurassic of Tanzania
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.

A. Stored as a stack. B. Bamboo corset in lateral view. C. Showing the labelling on the front side. The bamboo corsets are labelled with the quarry numbers and field numbers as assigned to single fossil blocks.

Fig. 8 in Research history, taphonomy, and age structure of a mass accumulation of the ornithopod dinosaur Dysalotosaurus lettowvorbecki from the Upper Jurassic of Tanzania
Fig. 8. Tentative reconstruction of the spatial relationships of the four bonebeds of the Ig/WJ-quarry according to the available descriptions and dates of Werner Janensch and Hans Reck. The actual shape and absolute sizes of the bonebeds are schematic and speculative. Top (A) and profile (B) views are in relation to the cardinal points. Note that the actual stratigraphic level of BB-1 in relation to BB-2 is uncertain (double headed arrow). The dotted ellipses show the approximate position of the large, possibly sauropod, bones found in September 1912 within the otherwise bone-free layer in between BB-3 and BB-4 including a scapula and a cervical vertebra. BB, bonebed. See Fig. 7 for comparison.
