Diagnosis
ReferenceDiagnosis
G. F. Wang et al. 2017Basal theropod distinguished by having parasagittal crests at least along orbital dorsal rims. Shuangbaisaurus also possesses a unique combination of features, including elevated ventral edge of the premaxilla (also present in Dilophosaurus and LFGT LDM-L10 of Sinosaurus), higher than long premaxillary body (also present in LFGT LDM-L10 of Sinosaurus, but longer than high in Dilophosaurus and KMV 8701 of Sinosaurus), and small upper temporal fenestra with its diameter shorter than the transverse width of the parietals in between and about half the length of the skull table posterior to the orbit.
