Figure 4
Visualizations of the module composition changes across phylogeny. The number of node-based modules ranged from 1 to 8. (A) shows the changes in module composition from Riojasuchus to Crocodylus. (B) shows the changes in module composition from Coelophysis to Gallus. (C) shows the difference in module composition among the ornithischian Psittacosaurus, the basal saurischian Eoraptor, and the sauropodomorph Plateosaurus. (D) Comparisons of the adult and juvenile stages of extant species. Adult Nothura and Geospiza are shaded in grey as one module was identified because of the small number of nodes and links due to a highly fused skull. Nodes were colored based on their modules. Composition of each module is listed in Supplementary Table 4.
