Figure 4 in The early evolution of titanosauriform sauropod dinosaurs

Figure 4. Character maps for some cladistic analyses of sauropod dinosaurs. The analysis presented in this study incorporates few cranial characters, reflecting the poor fossil record for titanosauriform skulls and standing in contrast to the pattern of character distribution in Diplodocoidea. Analyses that are wider in scope such as that of Wilson (2002) have a more even distribution of characters throughout the body.
