Ancestral range reconstructions from the Dispersal-Extinction-Cladogenesis analyses using a strict temporal calibration of the phylogeny.

<p>The exact temporal calibration displayed here is only for display purposes (i.e., some branches have been slightly lengthened for clarity). Rectangles indicate the stratigraphic ranges and associated uncertainty, black bars are the midpoint of these ranges, and wide bars represent the reconstructed ancestral range with the highest relative probability. Both the weighted and unweighted analysis results are shown here, because their highest relative probability results for each branch were the same.
