Diagnosis
ReferenceDiagnosis
D. C. Evans et al. 2017Large troodontid diagnosed by the following autapomorphies: (1) primary supraciliary foramen is truncated anteriorly by the lacrimal contact; (2) superficial (ectocranial) surface of the frontal proportionally shorter than all known troodontids, with a length to width ratio less than 1.3; and (3) a frontoparietal contact in which an enlarged lappet of the frontal extends medially to extensively overlap the lateral region of the interfrontal (anterior) process of the parietal.
