Fig. 7. Field sketches by Hans Reck (Reck, 8th report, September 15, 1912) on the spatial relationships of the two main bonebeds. The two main bonebeds (BB-3 and BB-4) in top (A) and profile (B) views. The indicated large bones in between are labelled with "dinosaur shoulder blade and vertebra" (in German) (A) or simply "Dinos." (B) and indicate the discovery of sauropod remains in the quarry (H. Reck, 8th report, September 15, 1912; Pal. Mus SII, Tendaguru-Expedition 9.5, Archive of the Historical Division of the MfN).图7 系汉斯·雷克（Hans Reck）于1912年9月15日提交的第8份报告中所绘野外手绘图，展示了两处主要骨层的空间分布关系。该图包含A、B两个视图，分别呈现两处主要骨层（BB-3与BB-4）的顶视图与剖面视图。图中标注的中间大型骨骼，在A图中以德语标注为“恐龙肩胛骨与椎骨”，在B图中则简写为“恐龙（Dinos.）”，表明该采石场中发现了蜥脚类（sauropod）化石遗存（数据来源：H.
