Figure 1. The strict consensus tree of 84 MPTs of length 445 inferred from unweighted parsimony analysis with all characters set as unordered (CI: 0.3640, RI: 0.7100).

Figure 1

Values at nodes indicate Decay Index >1 and bootstrap >0.5. In this and subsequent figures the number following each species name indicates the mean value of the tip prior (in Mya). Points on nodes indicate the extents of node-based clade names: R, Russellosaurina; Te, Tethysaurinae; Y, Yaguarasaurinae. Lines on branches indicate the extents of branch-based clade names: A, Aigialosauridae; G, Globidensini; H, Halisaurinae; Ma, Mosasauroidea; Me, Mosasaurinae; Mi, Mosasaurini; N, Natantia; P, Plioplatecarpinae; Ty, Tylosaurinae. The lightning bolt symbol indicates the names that self-destruct under the topology provided.
