Figure 15.

Illustration of the curvature of the tail in three specimens. In the first specimen (upper row, a-b) the tail shows a strong curve in the medial direction, observed in the superior view, and a slight curve in the inferior direction, as shown in the lateral view. In the second specimen, the tail shows very little curving in either direction (c-d). Finally in the third specimen (e-f), very limited curving is observed in the medial direction, however, stronger curving is observed in the superior direction in the lateral view.
