Figure 8J View FIG
A left dentary fragment of Parasaniwa containing three tooth bases, AMNH 8499 (fig. 8J), has been recovered from Clambank Hollow. The dentary consists of a large, ventrally convex tooth-bearing border which descends anteriorly to the ventral edge of the lower jaw. The tooth bases are prominently folded externally as well as internally. The number of folds exceeds that found in Paraderma and may be as high as 10 on the lingual side. The tooth base is not expanded and usually a small foramen is present on its posterior side.
The anterior portion of a maxilla, AMNH 8503, has been recovered from Clambank Hollow. Its teeth are identical to those found on the dentary and the anterior two or three are much smaller than the posterior teeth. Externally, the maxilla is smooth and the sculpturing is not so marked as in Exostinus or Paraderma .
