Extended Data Figure 1: Reduced strict consensus tree of the main analysis showing bootstrap frequencies (above node) and Bremer support values (below node) that were calculated for each of the major nodes, after the exclusion of Saltopus elginensis, Agnosphitys cromhallensis, Eucoelophysis baldwini and Diodorus scytobrachion.Hover over figure to zoom
Extended Data Figure 2: Strict consensus tree produced when Dimorphodon macronyx was included in the dataset and chosen as the outgroup taxon (Euparkeria capensis and Postosucus kirkpatricki were not included).Hover over figure to zoom
Extended Data Figure 3: Strict consensus tree produced when the non-dinosaurian silesaurid taxon Silesaurus opolensis was chosen as the outgroup taxon.Hover over figure to zoom
Extended Data Figure 4: Strict consensus tree produced when no characters were treated as ordered.Hover over figure to zoom
Extended Data Figure 5: Strict consensus tree set against the geological timescale, showing the predicted Early Triassic divergence dates of Dinosauria (star) and of the major dinosaurian lineages when the potential ‘massospondylid’ sauropodomorph Nyasasaurus parringtoni is included in the analysis.Hover over figure to zoom
