The skull was roughly triangular in profile. One specimen preserved a soft tissue crest or wattle on the head. The beak was toothless, and both the upper and lower beaks were extended by keratinous material. Teeth were present only in the maxillae (upper cheeks) and dentaries (main bone of the lower jaw). They grew in columns, with an observed maximum of six in each, and the number of columns varied based on the animal's size. There were 51 to 53 columns per maxilla and 48 to 49 per dentary (teeth of the upper jaw being slightly narrower than those in the lower jaw).
