Figure 13 in The cranial skeleton of the Early Permian aquatic reptile Mesosaurus tenuidens: implications for relationships and palaeobiology

Figure 13. Cladogram illustrating relationships of mesosaurs based on a PAUP analysis of a modified version of the data matrix in Laurin & Reisz (1995), with additional characters from Modesto (1999b). See text for discussion. Tree length = 328, consistency index (excluding uninformative characters) = 0.66, rescaled consistency index = 0.41.
