Figure 1

Jaws of Tenrec ecaudatus in lateral view. These images demonstrate how adult size in an afrotherian may be reached in the absence of many permanent cheek tooth loci. The old individual above has its complete permanent dentition erupted, showing p4-m2 worn down to their roots (UMZC H5431J, image reversed). The individual below is larger, but retains its deciduous canine through dp4; their permanent successors plus m3 are still unerupted within the dentary (BMNH 70.3.10.4). Scale bar (in millimeters) applies to both specimens. The dotted line from the condyle to symphysis on the top specimen represents measure taken of maximum jaw length, quantified in Figure 2.
