Fig. 5. Box-and-whisker plots showing the distribution of CCM2 and SCM2 data for several major clades of Mesozoic tetrapods. A. Comparison of SCM2 and CCM2 data for plesiosaurs. B. Comparison of CCM2 data for plesiosaurs, sauropodomorphs (from Mannion and Upchurch 2010), birds (from Brocklehurst et al. 2012), and pterosaurs (from Dean et al. 2016). C. Comparison of SCM2 data for plesiosaurs, ichthyosaurs (from Cleary et al. 2015), and sauropodomorphs (from Mannion and Upchurch 2010). All silhouettes are from phylopic.org, and are credited to Adam Stuart Smith (Plesiosaurus), Scott Hartman (Brachiosaurus), T. Michael Keesey (Archaeopteryx), and Gareth Monger (Pterodactylus, Ichthyosaurus). Abbreviations: CCM, character completeness metric; SCM, skeletal completeness metric (for detailed explanation of terms see Completeness metrics in Methods section).
