Ventral view of Langebaanweg Agriotherium maxillary fragment, L45137. Apart from their large size, the incisors of A. africanum are unremarkable and are little different from those of living Ursinae. Dimensions of some incisors were given elsewhere (Hendey 1977, tables 2, 5). The I2 is distinct in having two lingual cusps projecting from the V-shaped cingulum posterior to the principal (spatulate) cusp. The lateral accessory cusp is the smaller and the more anteriorly situated, being little more than a small projection from the cingulum. The other accessory cusp is much larger, covering much of the lower part of the lingual surface, although it is still much smaller than the principal cusp (Fig. 8). In older individuals ( L45062) the three cusps develop horizontal wear facets in a single plane. The I1 is similar to I2, but smaller, while the I3, which is the largest of the incisors, is morphologically similar to its counterpart in Ursinae. The lower incisors are similar to those of Ursus arctos and other ursines, and are distinguished only by their larger Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
