Figure 8 in Sauropod dinosaur phylogeny: critique and cladistic analysis

Figure 8. Minimum implied gap (MIG) predicted by the topologies of Wilson & Sereno (1998), left, and Upchurch (1998), right. Grey bars indicate missing lineages as implied by sister-taxon relationships. The dashed bar denotes an missing interval for Diplodocoidea that is implied by the late appearance of the controversial species Antarctosaurus wichmannianus (Huene, 1929), here regarded as a rebbachisaurid (see Table 13). Timescale based on Harland et al. (1990).
