FIGURE 15 in A phylogeny of Plesiosauria (Sauropterygia) and its bearing on the systematic status of Leptocleidus Andrews, 1922

FIGURE 15. Hypotheses of relationship among plesiosaurs for which all taxa having greater than 60 percent (A), 50 percent (B), and 40 percent (C) missing data are excluded. (A) Strict consensus of two most parsimonious trees (tree length = 5584; CI = 0.545; RI = 0.553; RC = 0.302) of 27 OTUs and 152 characters; (B) single most parsimonious tree (tree length = 5081; CI = 0.550; RI = 0.534; RC = 0.294) of 23 taxa and 152 characters; (C) single most parsimonious tree (tree length = 4429; CI = 0.604; RI = 0.527; RC = 0.318) of 18 taxa and 152 characters. The OTU Callawayasaurus colombiensis represents the composite scoring.
