Diagnosis
ReferenceDiagnosis
E. A. Maleev 1956Large quadruped dinosaurs with heavy armor. The skull is not large, triangular in shape, slightly greater in length than in width. Lamellar leathery ossifications completely cover the surface of the skullcap and sides of the cranium. The rear border of the skullcap is deviated with rows of small spines. The ribs are massive. Between the central rib and its distal end there is a rough spot, morphologically similar to the hook-like outgrowths of other reptiles. The first caudal vertebrae are short and high. The vertebrae of the rear half of the tail are long, narrow, fused to the body, forming a solid 'hammer' or 'club' not less than 1 meter in length.
P. Penkalski 2018Genus monotypic, as for the type species.
