Extended Data Fig. 4: Maximum clade credibility trees returned by Bayesian phylogenetic inference, and strict and reduced strict consensus trees returned by parsimony-based phylogenetic analyses.

a, Maximum clade credibility (MCC) tree of the Bayesian analysis of the Baron et al.^39,61,62,63 matrix. Posterior probabilities for each node reported in the online supplement. b, MCC tree of the Bayesian analysis of the Cabreira et al.²⁶ matrix. Posterior probabilities for each node reported in the online supplement. c, MCC tree of the Bayesian Langer et al.⁵³ matrix, including Saltopus. Posterior probabilities for each node reported in the online supplement. d, Reduced strict consensus of the Langer et al.⁵³ parsimony analysis, excluding character 217 (61,408 MPTs of 1,958 steps; CI = 0.269, RI = 0.617). Strict consensus and supporting synapomorphies reported in the online supplement. e, Reduced strict consensus of the Langer et al.⁵³ parsimony analysis, excluding character 217 and the taxa Saltopus, Agnosophitys, and Nyasasaurus (99,999 [memory overflow] MPTs of 1,942 steps; CI = 0.271, RI = 0.621). Strict consensus and supporting synapomorphies reported in the online supplement. f, Reduced strict consensus of the Baron et al.^39,61,62,63 parsimony analysis, excluding character 217 (99,999 [memory overflow] MPTs of 1,923 steps; CI = 0.274, RI = 0.615). Strict consensus and supporting synapomorphies reported in the online supplement. g, Reduced strict consensus of the Baron et al.^39,61,62,63 parsimony analysis, excluding character 217 and the taxa Saltopus, Agnosophitys, and Nyasasaurus (61,680 MPTs of 1,907 steps; CI = 0.276, RI = 0.619). Strict consensus and supporting synapomorphies reported in the online supplement. h, Reduced strict consensus of the Cabreira et al.²⁶ parsimony analysis (336 MPTs of 866 steps; CI = 0.336, RI = 0.631). Strict consensus and supporting synapomorphies reported in the online supplement. i, Reduced strict consensus of the Cabreira et al.²⁶ parsimony analysis excluding Saltopus (84 MPTs of 861 steps; CI = 0.338, RI = 0.634). Strict consensus and supporting synapomorphies reported in the online supplement.
