The symphysial portion is long, narrow, and spout-like, and the coronoid process is small. |
Anteriorly, the symphysial surface is raised above the adjacent bone and is divided into an upper and lower arm, which meet anteriorly and diverge posteriorly. |
The symphysial end of the dentary is too crushed to permit estimation of its proportional participation in the symphysis. |
In Choloepus the symphysial part is drawn out in a somewhat spout-like manner. |
