Fig. 15. A combination of archival photographs (UAT 678/73) showing a mounted 'Pachysaurus ajax' von Huene, 1905 from Wüstenroth (GPIT-PV-30790) and "Teratosaurus" suevicus Mayer, 1861 from Aixheim, Löwenstein Formation (GPIT-PV-60297); these specimens were as one skeleton mounted in 1905 by Ernst von Koken (1860–1912), von Huene's teacher, to show the overall size of the dinosaurs from the region.

Fig. 12. Archive photograph (UAT 678/73) of the mounted specimen. The skeleton mount was given the collection number GPIT-PV-30790 (ca 1901). Some elements from this mount have recently been rediscovered as items stored in individual boxes, along with an old sheet of paper (undated) indicating where each element belonged. However, we are not certain that the elements in these boxes have not been misplaced given these elements were uncatalogued until March 2022.

Fig. 14. Plate showing the arrangement of the sauropodomorph skeletons on display in the diorama drawn by von Huene (GPIT-PV-117991, on display in the Stratigraphic Hall) as shown in Fig. 13. "GPIT V" corresponds to 'Pachysaurus wetzeli' von Huene, 1932, collected from the upper bone bed from the Obere Mühle, Trossingen. "GPIT VI" corresponds to Plateosaurus 'quenstedti' von Huene, 1908, a hindlimb still in the original matrix collected from the upper bone bed from the Obere Mühle, Trossingen. "GPIT III" refers to Plateosaurus robustus (von Huene, 1905), collected from the upper bone bed from the Obere Mühle, Trossingen. Finally, "GPIT VII" refers to 'Pachysaurus ajax' von Huene, 1905, a skeleton collected from Wüstenroth, near Löwenstein. Explanation of the numbers: 2. = cervical vertebrae; 3. = dorsal vertebrae; 5. = caudal vertebrae; 6. = scapula (shoulder blade); 7. = coracoid, attached to which are rudiments of the clavicles (collar bones); 8. = fumerus (upper arm); 9. = radius and ulna (forearm); 11. = ilium; 12. = pubis; 13. = ischium; 14. = femur (thigh); 15. = tibia and fibula (lower leg); 16. = pes; 17. = abdominal ribs [see rest of the figure in Fig. 22].
