Silhouettes are from phylopic.org, and are credited to Adam Stuart Smith (Plesiosaurus) and Scott Hartman (Brachiosaurus).

    Techniques Used:

    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).

    Techniques Used: Comparison

    Results of pairwise comparisons between time series using Pearson’s product-moment correlation coefficients. All time series were log-transformed and subjected to generalised differencing prior to comparisons being made. Asterisks indicate statistically significant results.

All time series were log-transformed and subjected to generalised differencing prior to comparisons being made. Asterisks indicate statistically significant results.

    Techniques Used:

    A. Plesiosaur CCM2 versus species richness. A weak but significant correlation between the two is driven largely by an influential data point, the Aalenian. B. Plesiosaur SCM2 versus fossiliferous marine formations (FMFs). A weak but significant correlation between the two is driven largely by an influential data point, the Aalenian. The scatterplot for CCM2 versus FMFs (not shown) shows a largely identical pattern. C. Plesiosaur SCM2 versus ichthyosaur SCM2. Silhouettes are from phylopic.org, and are credited to Adam Stuart Smith (Plesiosaurus) and Gareth Monger (Ichthyosaurus).

    Comparison:

    Article Title: The completeness of the fossil record of plesiosaurs, marine reptiles from the Mesozoic
    Article Snippet: Two variants of the metric were proposed by Mannion and Upchurch (2010) : CCM1 estimates the completeness of the most complete specimen of a given species, whereas CCM2 estimates completeness based on all specimens referred to that species.

    Article Title: Preservational bias controls the fossil record of pterosaurs
    Article Snippet: CCM2 ( sensu Mannion and Upchurch 2010a ), combining the information of all specimens of a taxon to attain overall completeness, has been deemed more appropriate for comparisons between fossil record quality and diversity ( Brocklehurst et al . 2012 ), and has thus been employed here.
