Figure 4. — Condensed cladogram based on the strict consensus of 28 most parsimonious trees (tree length = 1119) obtained from a cladistic analysis of a modified version of the Yates (2007) matrix (353 characters; see the electronic supplementary material for details) after the a priori removal of the poorly known, and unstable taxa: Plateosaurus (=Gresslyosaurus) ingens, Camelotia, Blikanasaurus and Isanosaurus (leaving 44 active taxa in the analysis). Only the plateosaurian part of the tree is shown here. Named suprageneric taxa are collapsed into single terminals to save space: Plateosauridae contains Unaysaurus, Plateosaurus gracilis and Plateosaurus engelhardti; Riojasauridae contains Riojasaurus and Eucnemesaurus; Massospondylidae contains Massospondylus, Coloradisaurus and Lufengosaurus; Eusauropoda contains Shunosaurus, Omeisaurus, Mamenchisaurus, Barapasaurus, Patagosaurus, Cetiosaurus and Neosauropoda. Bold numbers given at each node are decay indices, the percentages are bootstrap support values. The star marks the basal node of the quadrupedal clade.
