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.

Figure 3 in Post-Gondwana Africa and the vertebrate history of the Angolan Atlantic Coast
Figure 3. Northward drift of African and South American conjugate basins relative to Hadley Cells and the chronology of the South Atlantic Ocean. Inset shows conjugate Sergipe-Gabon and Campos- Kwanza basins in South America and Africa. From the initial opening of the South Atlantic Ocean heralded by the Etendeka-Paraná Large Igneous Province (LIP), the basins drifted from their starting position in interior Gondwana. As the width of the South Atlantic has grown, Africa has also drifted north relative to South America and through the latitudes of the descending limb of the southern Hadley Cell.
