Sheil and Greenbaum (2005) suggest that the bones of the dermatocranium were grouped into elements of the palatum (pterygoid, vomer and palatine), maxillary arch (premaxilla, maxilla, jugal, quadratojugal and squamosal) and the roof of the cranium (prefrontal, postorbital, frontal and parietal).
Two flat elements, presumably the ventral surface of the parasphenoid (pa) and a small portion of the vomer (vo), are visible.
The premaxilla is too long and slender, there is no palatine process of the premaxilla, there is no bone in the nasal septum, the vomer bears no horns, and the rostral palatines aren't twisted, etc.
The anterior teeth of the second lateral rows are barely evident along the labial margin of the vomer, and on several teeth the pulp cavity has been exposed.
2) A rare cause is congenital agenesis of the os vomer.
A very large canine tooth inserted on the distal part of the vomer is considered diagnostic for specific identification; however, one of the examined specimens showed two canine teeth.

3) in HL; lips thin; teeth conical with slightly curved tips, those on upper jaw mainly on outer surface of lips; teeth of upper jaw in about 4-5 irregular rows anteriorly, reduced to 1-2 rows posteriorly, where exposed when mouth closed; teeth in lower jaw in about 7-8 irregular rows anteriorly, reduced to 2-3 rows posteriorly; teeth generally absent on vomer and palate, except small vestigial patch of vomerine teeth on one side of holotype and two paratypes; roof of mouth and upper surface of tongue covered with numerous slender papillae.
The nasal mass was seen occupying the sphenoethmoid recess; it had arisen from the nasal septum on the posterior part of the vomer (figure 1).
Maxilla bearing large condyle for articulation with vomer, biconcave submaxillary meniscus interposed between maxilla and vomer.

Teeth in villiform bands in the premaxilla and palatines and in a small patch on the vomer, premaxilla with an outer row of moderate conical teeth; outer teeth anteriorly with irregular inner series of smaller conical teeth and a wide inner band of much smaller teeth; small canine teeth in mandible and at premaxillary symphysis.
