Figure 27 in Phylogenetic analysis, taxonomic revision, and dental ontogeny of the Cretaceous Zhelestidae (Mammalia: Eutheria)

Figure 27. Seven stages of dental replacement in the lower dentition of zhelestids from the canine posteriorly. See text and Figure 28 for specimens upon which the first five stages are based. Shading is as follows: deciduous teeth, black; permanent teeth, dark grey; premolars for which only one generation is known, light grey. Cross hatching indicates the condition is speculative for that stage.
