FIGURE 5. A cladogram showing the phylogenetic position of Manchurochelys manchoukuoensis. Data matrix including 20 taxa and 43 characters is modified from Vandermark et al. (2009), which in turn is based upon the data matrix of Parham & Hutchison (2003). A 50% majority-rule consensus tree was derived from 20 most parsimonious trees with tree length of 89 (CI = 0.52, RI = 0.77, RC = 0.40). The scoring of Manchurochelys manchoukuoensis was as follows: 00?0?11110?0?1?11111 11????1101 0??111???? 000.
