Figure 5 in Reassessment of the Lower Cretaceous (Barremian) pliosauroid Leptocleidus superstes Andrews, 1922 and other plesiosaur remains from the nonmarine Wealden succession of southern England

Figure 5. Phylogeny of Plesiosauria using the character matrix of O'Keefe (2001, 2004a) with rescored data for some Leptocleidus-like taxa (see Appendix). Strict consensus maximum parsimony trees with multistate characters ordered (A, B) vs. unordered (C, D); and excluding taxa incorporating> 65/55% missing data (B, D: see text for details). Bayesian tree with multistate characters unordered (E) and then excluding taxa incorporating>65%/55% missing data (F, ordered vs. G, unordered). Boxed numbers represent character states (A–D)/posterior probabilities (E–G) at selected nodes (•); *plesiomorphic state; †reversal. Bootstrap/Bremer support values for major clades are given in the text.
