Analysis 1 Strict consensus from 148 MPTs obtained from iteration 1.1. Analysis 2 Strict consensus from 149 MPTs. The values on the branch are bootstrap values from 100 replicates, reported in absolute values. The clade ‘Sauropoda’ is here used sensu lato to include all the taxa that collapsed in a polytomy with eusaropods since there is not a phylogenetic definition of Sauropoda. The pruned tree was calculated by performing an iterative positional congruence (reduced) analysis (iterPCR, Pol and Escapa 2009) in TNT; the analysis identified Chromogisaurus, Pulanesaura and Meroktenos as unstable taxa, and the new tree comes from a new technology search excluding these three taxa. Sauropoda and Eusauropoda, both sensu Sander et al. (2011), are better displayed in the pruned tree, and Tuebingosaurus and Schleitheimia are better displayed grouped with Isanosaurus as very derived early-diverging sauropods, and Ohmdenosaurus as a eusauropod.
