The upper teeth are denoted I 1, I 2, C −, Pm 3, Pm 4, M 1, M 2, and M 3. Left or right has to be specified. The lower teeth are I 1, I 2, C −, Pm 3, Pm 4, M 1, M 2, and M 3. The reason the premolars are labeled 3 and 4 is that in earlier primates there were two other premolars between them and the canines. [5]

The occurrence of ...
