Templeton tests of the significance of tree length differences of various alternative topologies as compared to the most parsimonious tree shown in Fig. 6A. Only alternative topologies AT7, AT8, and AT9 can be rejected by the data with confidence. N  =  number of deviations in step counts found; n  =  number of deviations favoring the alternative topology; T_s  =  test statistic (summed ranks of n-values). Alternative topologies tested: AT1, Barapasaurus + Patagosaurus monophyletic sister group to Mamenchisauridae + more derived eusauropods; AT2, Barapasaurus + Patagosaurus monophyletic sister group to Mamenchisauridae; AT3, Barapasaurus + Patagosaurus monophyletic sister group to Jobaria + more derived eusauropods; AT4, Spinophorosaurus + Tazoudasaurus monophyletic; AT5, Spinophorosaurus + Shunosaurus monophyletic; AT6, Spinophorosaurus + Mamenchisauridae monophyletic; AT7, Barapasaurus + Patagosaurus monophyletic sister group to Spinophorosaurus + Eusauropoda; AT8, Shunosaurus + Mamenchisauridae monophyletic; AT9, Spinophorosaurus + Shunosaurus + Mamenchisauridae monophyletic sister group to the remaining Eusauropoda; AT10, Cetiosaurus sister taxon to Shunosaurus + more derived eusauropods; AT11, Cetiosaurus sister taxon to Patagosaurus + more derived eusauropods; AT12, Cetiosaurus sister taxon to Jobaria + Neosauropoda; AT13, Cetiosaurus sister taxon to Barapasaurus + more derived eusauropods; AT14, Barapasaurus + Cetiosaurus + Patagosaurus monophyletic.
