Figure 25. Stratigraphic consistency in suboptimal and randomly generated trees. Histogram shows the minimum implied gap (MIG) implied by different topological rearrangements within Titanosauria; non-titanosaur relationships were fixed (see upper right inset). The MIGs for MPTs from the original analysis (MPTOr; 383 million years) and rescored analysis (MPTRe; 323–343 million years) are indicated by the horizontal spans above the histogram. Note that the fixed topology for non-titanosaurs used the more stratigraphically consistent of two sets of relationships among basal sauropods. Orange bars represent MIGs for up to 10 000 suboptimal trees two, five and nine steps longer than the MPT (s) generated by the rescored Tapuiasaurus matrix. Blue bars represent MIGs for 10 000 randomly selected trees of any length. MIGs for the MPTs are on the left tail of the distribution for random trees, but they fall closer to the centre of the distribution for suboptimal trees.
