Time-calibrated phylogenetic analysis.
Tree showing placement of T. regalis, A. elainus, S. robusta, B. grandis, P. mauritanicus, and aff. Quetzalcoatlus. Maximum parsimony analysis of the character-taxon matrix (S1 Data) recovered 4 most parsimonious trees with length 1,126.651 (consistency index = 0.336, retention index = 0.793). Divergence dates are set at 1 Ma, and ranges show the resolution of stratigraphic dating.
