The only other identifiable cranial element is the quadrate, which shows no useful details. The lower jaws are preserved, although distorted. The dentary is slender and straight laterally, but bows medially in dorsal view. There are at least fifteen teeth, which are placed in separate alveoli. It is said to be different than the large, triangular fenestra of dromaeosaurids .
Teeth vary with position.
The premaxillary and anterior dentary teeth are flattened, recurved and lack serrations. Their roots are of normal theropod type. Posterior teeth possess posterior serrations, but no anterior serrations. Their crowns are not as compressed and they have constricted roots. Serrations are not enlarged, numbering 13-14 per mm on a 2 mm tooth crown.
