Diagnosis
ReferenceDiagnosis
V. M. Arbour and P. J. Currie 2016Uniquely amongst ankylosaurids, has bulbous, ridge-like loreal caputegulum, and quadratojugal horn with anteriorly positioned apex. Differs from all other ankylosaurs in possessing the following combination of characters: conical frontonasal caputegulae with circular bases (also present in Talarurus); unlike Talarurus, lacks V-shaped upraised area of frontals; lacrimal caputegulum smaller, more square than in Ankylosaurus, Anodontosaurus, Euoplocephalus.
