Figure 6 in Dental enamel structure in long-nosed armadillos (Xenarthra: Dasypus) and its evolutionary implications

Figure 6. Parsimonious reconstruction of ancestral enamel character states in cingulates. Character 1 is a binary character 'presence of enamel in permanent teeth' [present (0); or absent (1)], and character 2 is the multistate character 'enamel complexity in permanent teeth' [complex multilayered prismatic enamel (0); reduced, thin layer of prismatic enamel (1); or prismless enamel (2)]. Shaded circles, not applicable.
