Diagnosis
ReferenceDiagnosis
X. Xu et al. 2006Medium-sized tyrannosauroid with the following autapomorphies: a deep and narrow groove along the anterior margin of the premaxilla; a distinct opening on the maxilla close to the premaxilla–maxilla contact; a complex, highly pneumatic nasal crest; a low, rugose ridge along the midline of the frontals; a dorsally flattened parietal with two parallel sagittal crests; a transverse ridge within the supratemporal fossa; a centropostzygapophyseal lamina on cervicodorsal vertebrae with its dorsal end expanding laterally; deep, longitudinal sulci on both ventral and dorsal surfaces of the distal caudal vertebrae (independently evolved in troodontids8); ventral part of scapular blade with sub-equilateral triangular cross-section and thick posterior margin; metacarpal II with prominent medioventral and laterodorsal processes proximally; manual phalanx II-2 with prominent medioventral process proximally; femoral greater trochanter much narrower anteroposteriorly than the lesser trochanter; distinct fossa on posterodistal surfaces of astragalus and calcaneum; and pedal phalanx II-1 with prominent paired ventral processes proximally.
