Figure 4. Strict consensus trees produced by the alternative tests using a single ‘dolichosaur’ taxon as outgroup.

Figure 4

Trees rooted on (A) Adriosaurus suessi (40 MPTs), (B) Dolichosaurus longicollis (140 MPTs), and (C) Pontosaurus kornhuberi (20 MPTs) 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.
