Figure 15. Results of first phylogenetic analysis based on data set of Lacovara et al. (2014). Strict consensus of 40 equally most parsimonious trees (length = 958 evolutionary steps; consistency index = 0.4238, retention index = 0.7072) set upon a geological timescale (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. 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%.
