With the exception of the ectoptery- goid, the paired palatal l)Oiies hear denticles; in addition, three major rows of large teeth radiat(> laterally, diagonally, and anteriorly from the hasicranial artienlation. Small den- ticles arc also present on the parasphenoid. The palate is anchored directly to the dermal sknll roof at three points: anteriorly to the premaxilla and laterally to the maxilla and to the jngal. Posteriorly, the palate is indi- rectly anchored to the skidl roof by the (jnad- rate and the braincase. The oceijiital condyle is set only slightly anterior to the posterior margin of the jaw articulation. The subtem- poral fossae are quite large, occupying about 23 per cent of the palatal area.
