Figure 4 in Integration patterns of cheek teeth and ecomorphological evolution in grinding herbivores: the case of caviine rodents (Caviomorpha: Caviidae)

Figure 4. Summary scheme of the shape optimization analyses of p4-m3 (lower diagrams) and P4-M3 (upper diagrams) onto a phylogenetic metatree (see Material and Methods section) using parsimony. Discussed ancestral reconstructions and terminal configurations at the generic level are illustrated (for the complete sets of ancestral reconstructions and terminal configurations at the species level, see Supporting Information, File S4). Red trails indicate trajectories of landmarks from the previous reconstruction. The extinct species are indicated by a cross. For fossils represented only by a single series, greydash diagrams represent the missing configurations illustrated by the closer ancestral reconstructed series.
