From: A New Clevosaurid from the Triassic (Carnian) of Brazil and the Rise of Sphenodontians in Gondwana
Phylogenetic analyses evidencing the position of Clevosaurus hadroprodon sp. nov. within Rhynchocephalia using two distinct optimality criteria. (a) Resultant topology of the strict consensus of eight most parsimonious tree (249 steps each) (CI = 0.43; RI = 0.69); (b) Majority-rule consensus tree derived from the Bayesian analysis. Nodes values represent posterior probabilities. (Note that Clevosauridae sensu Bonaparte and Sues, was not recovered as a monophyletic group in both analyses and the genus Clevosaurus was not recovered as monophyletic in the Bayesian topology). Abbreviations: “Cle”: Clevosauridae; Hom: Homeosauridae; Pleu: Pleurosauridae; Opi: Ophistodontia.
