Figure 17. Results of the second analysis. Single resolved tree (length = 145 evolutionary steps, consistency index = 0.6966, retention index = 0.7124) generated by the second analysis based on data matrix of Gonźalez Riga & Ortiz David (2014) after Drusilasaura was deleted from the analysis, and set on a geological time scale (Gradstein et al. 2012). Thickened branch sections indicate approximate temporal range for each terminal taxon. Temporal ranges of taxa were taken from multiple sources (Borsuk-Bialynicka 1977; Upchurch et al. 2004; Weishampel et al. 2004; de Jesus Faria et al. 2015). Open circles at nodes indicate a node-defined clade name. Arcs on branches indicate a stem-defined lineage name. See Table 1 for name definitions. Lo. = Lognkosauria. Op. = Opisthocoelicaudiinae. Numbers at nodes indicate bootstrap and decay index (Bremer value), formatted as decay index/bootstrap value. A dash (-) indicates a decay index of 0 and/or bootstrap value <50%.
