Maxillary teeth smallest anteriorly, 12-15, followed after a gap by two large grooved fangs located just behind the posterior border of the eye.
32.
Maxillary teeth 20-25, subequal, except for the 3-5 most posterior, which are slightly enlarged and grooved on the outer surface.
33.
It has a singular postocular scale rather than two, fewer ventral, supralabial, and infralabial scales, a shorter tail, and fewer maxillary teeth.
34.
Ventral view of a Temnospondyl Skull showing Interpterigoid Vicuity Another distinct feature that Dissorophus has is that the maxillary teeth extend further back ventral to the squamosal.
35.
Basal traits include a prominent paraquadratic foramen at the quadrate in the skull; maxillary teeth with only seven denticles at the margin; and a shoulder spine.
36.
On each side of the upper jaws there were four premaxillary and twelve maxillary teeth, while the lower jaws were equipped with fifteen dentary teeth per side.
37.
The premaxillary teeth are positioned vertically, the maxillary teeth incline to the front while the teeth of the lower jaw incline to behind, a unique configuration.
38.
Maxillary sinusitis is common due to the close anatomic relation of the frontal sinus, anterior ethmoidal sinus and the maxillary teeth, allowing for easy spread of infection.
39.
Very basal ornithischian traits included the presence of six teeth in the premaxilla with only a short toothless sector in front and a short hiatus with the maxillary teeth.
40.
As a general rule, four teeth erupt for every six months of life, mandibular teeth erupt before maxillary teeth, and teeth erupt sooner in females than males.
