These specimens differ noticeably from the individual from Chinaj in the number of vomerine teeth and in coloration. |
The upper tooth structures are attached respectively to the ethmoid or vomerine region of the skull, and to the palato-pterygoids. |
The posterior vomerine teeth evidently met the posterior teeth of the mandible. |
The patches of vomerine teeth lie between the posterior margins of the choanae. |
A strong series of vomerine teeth extends across the palate. |
In many specimens the vomerine ridges are larger and more closely approximated medially than in the specimen described above. |
