“Observed diversity” (blue) in number of genera, “total diversity” (red) including “observed diversity” plus Lazarus taxa and ghost lineages, and average ghost lineage duration (green) for the coelacanths from the Late Permian to the present (in millions years). The value of the average ghost lineage duration for Present, not shown on the graph, equals 245 ma. See text for further explanation. E Early, M Middle, L Late
