- Dentary additionally seems instantly
- Had an opening between the entrance 24 enamel and again 8 enamel, however which may be because of person variation
- Enamel weren’t serrated
- Probably the most few troodontids with unserrated enamel
- Different troodontids with unserrated enamel come with Archaeornithoides, Byronosaurus, and Mei
- Seems very similar to Byronosaurus and Mei, however has variations in grooves and teeth crowns and is greater than Mei
- Carefully associated with Byronosaurus and Xixiasaurus
