Fig. 5 in Early giant reveals faster evolution of large body size in ichthyosaurs than in cetaceans

Fig. 5. Exploration of the rate heterogeneity of body-size evolution. (A and B) Ichthyosaurs (A) feature the fastest rates of body evolution early in their history, whereas cetaceans (B) show a more complex pattern, with fastest rates occurring in later stages of their history. C, Cymbospondylidae; M, Merriamosauria.
