FIGURE 4. Representative species-level paleogeographic reconstructions. (1-6) Range reconstructions for a carryover species, Hebertella occidentalis in the C1 through C6 sequences, (7-9) Range reconstructions for a Edenian to Maysvillian restricted species, Dalmanella multisecta in the C1 through C3 sequences, (10-12) Range reconstructions for a native descendant species, Platystrophia acutilirata in the C4 through C6 sequences, (13-15) Range reconstructions for an invasive species, Rhynchotrema dentatum in the C4 through C6 sequences.
