Calibrated cladogram corresponding to the cladistic analysis performed here (4500 most parsimonious trees, length of 943 steps, CI = 0.316, RI = 0.778, RC = 0.246), in which the position of all representatives of Perichelydia (sensu3) is shown, as well as that of the crown group Testudines. This distribution is based on the strict consensus tree, except in the case of the clade Meiolaniformes, which is obtained in the majority rule tree (67%). The paleobiogeographic distribution of each taxon is indicated. Bremer support values are shown.
