A similar ridge is also present in other troodontids, the posterior process is short and deep, and has a lateral surface that is depressed into the articular facet for the quadratojugal. The subtriangular pterygoid ramus is relatively small, narrow dorsally and wide ventrally, with the peak close to the ventral end of the quadrate.
The left quadrate is a posteriorly curved bone with a height of 22 mm. In most non-avialan theropods, the peak is more dorsally positioned.
A prominent ridge extends along the anterior edge of the lateral surface of the descending process, which is anteroposteriorly wider than transversely thick.
Both nasals are preserved but neither provides much morphological information.
The lateral surface of the surangular is dorsoventrally convex.
Otherwise the cranium indicates the presence of a sub-triangular cranial lateral profile, as in many other basal paravians.A tri-radiate bone is identified as the left postorbital.The jugal process is the longest one of the three processes but does not seem as long as in other basal troodontids such as Sinovenator.Both frontals are nearly complete, and exposed in ventral view.The frontal is about 1.8 times as long anteroposteriorly as transversely wide.
