Paleobiogeographic distribution of common clam shrimp species from the Upper Triassic of the basins of northern South America and the rift basins of central Pangea. (A) Late Tuvalian-early Lacian. (B) Lacian. (C) Alaunian-early Sevatian. The red lines represent the rifting zones of central Pangea during the Late Triassic2,5,6. The scheme was developed based on paleogeographic reconstructions for the Late Triassic57,58. Figure drawn with Inkscape 1.2.2 (https://inkscape.org/).
