Figure 11 in Sauropod dinosaur phylogeny: critique and cladistic analysis

Figure 11. Upchurch (1998) continued. A, 50% majority-rule consensus of 15 trees produced when all characters are left unordered. B, most parsimonious tree when only characters C75−C79 are left unordered. Dashed lines indicate nodes that collapse in a 50% majority-rule consensus of trees two steps longer than the most parsimonious tree.
