Figure 3.

Distribution of the selected taxa in the morphospace of inner ears plotted against the first three phylogenetic principal components (PPCs). Note how Dinilysia (black dot) occupies a position on the periphery of the main cluster in all plots except (c). (a) PPC2 plotted against PPC1; (b) PPC3 plotted against PPC1; (c) PPC2 plotted against PPC3. Diagrams are projections of the Procrustes landmark configurations of actual specimens located towards the positive and negative extremes of each axis and as close as possible to the origin of the orthogonal axis; all projections are in lateral view, anterior to the right. Colour coding is the same as in figure 2. The names of the taxa that are closest to Dinilysia in each plot are shown; for all other taxa see electronic supplementary material S4, table S2, where species names are provided for all numbers.
