The skull is long and narrow broadly rounded anteriorly with the sides diverging slightly and regularly in the anterior four-fifths of the length.
The orbit of Chenoprosopus milleri is nearly round and is about 32 mm.
in diameter.
It is smaller than Nigerpeton ricqlesi.
The orbits are positioned midway along the skull length and widely spaced.
The plane of the orbit is parallel with the lateral margin of the skull and is directed out and slightly upward.
The orbit depression extends back and slightly down for a short distance from the middle of the posterior border and lies a little behind the naris and in a line with the orbit and the naris.
The naris has a rounded and is approximately 10 mm wide and 7 mm long.
The shape of nasals are large, rectangular, and about three times as long as wide.
It is placed near the lateral margin of the skull and about 50 mm behind the tip of the rostrum.
Its plane is directed out and upward.
The otic notch is deep, open fully posteriorly and separated from the supratemporal and squamosal.
The jugal is a large element extending from the anterior border of the orbit back at least as far as the ear opening.
The upper side of the quadrate is thin, with plate-like bone extending up and forward as if to connect with the skull just above the otic notch.
The septomaxillae are small, triangular elements, fully twice as long as wide, and form nearly the entire posterior border of the naris.
It extends back between the nasals and the maxilla, but are apparently separated from the lachrymals by a considerable space.

The premaxilla of Chenoprosopus number approximately 20 (Hook, 1993) and have a short contact with the maxilla at the skull margin.
The maxilla is excluded from the narial opening by the septomaxilla.
The bases of the maxillary teeth are placed closely to the external margin of the maxilla.
The estimated minimum number of maxillary tooth positions is 34.
The first two maxillary teeth are smaller than the adjacent position of the premaxillary dentition tooth size.
These teeth have relatively narrow, round bases, recurved distal halves, and sharply pointed ends.
Also, the maxilla is excluded from the narial opening by the septomaxilla.
A short maxilla-nasal suture is evident on both sides of the skull, followed by contacts with the lacrimal and jugal.
