Diagnosis
ReferenceDiagnosis
L. Xing et al. 2024An ankylosaurine with dual jugal/quadratojugal horns. This taxon is also distinguished from all other ankylo-saurines with a unique combination of the following characters: protruded premaxilla such that prenarial portion is longer than infranarial portion (also present in Zhongyuansaurus luoyan-gensis), distinct 'postfrontal' caputegulum (also in Pinacosaurus mephistocephalus and Talarurus plicatospineus), well-developed supraorbitals forming no lacrimal incisure or postorbital peak (potentially controlled ontogenetically), parasagittaly projecting squamosal horn (also in Scolosaurus cutleri/Oohkotokia horneri), nuchal horn (also in Ankylosaurus magniventris, Euoplocephalus tutus, Nodocephaosaurus kirtlandensis, Zuul crurivastator), and polygonal, monotypic gular osteodrms covering the interman-dibular region and the entire throat (polymorphic gular osteo-derms occur in Jinyunpelta sinensis).
