KT-12/H1 is a partial mandible, and includes the crowns of the left P3 through C1 and the right I2 through P4, as well as the alveoli of the left I2, the I1, and the right I11. This specimen shares many similarities with Au. afarensis, including large incisiform canines and P3s that are bicuspid1. However, KT-12/H1's premolars are clearly three-rooted (unlike those of Au. afarensis, which may be two- or three-rooted), and the cheek tooth rows are divergent (as opposed to parallel)2. The premolar occlusal enamel is also thinner in KT-12/H11.
