Diagnosis

Reference	Diagnosis
E. A. Maleev 1956	Large quadruped dinosaurs with heavy armor. The cranium is not large, of trapezoidal shape. On the top of the cranium there are many covering bones. The cervical vertebrae are short and high. The dorsal vertebrae are long, centra are high; articular surfaces are flattened. Lumbar ribs (4-5) are firmly joined by the lateral processes of the vertebrae. The scapula is twice as long as the humerus. The articular cavity is large, of circular shape, extended cranio-caudally. The humerus is somewhat longer than the tibia, and double the length of the radius. The ratio of the humerus to the femur is 3:2.
T. A. Tumanova 1987	Distinct pyramidal scutes distributed above and behind orbits; skull roof covered with small tubercular osteoderms; occipital plane perpendicular to skull roof; paroccipital processes inclined somewhat posterolaterally; occipital condyle narrow oval, posterolaterally inclined; quadrate not attached to paroccipital processes; basioccipital with medial protuberance, depressions on sides of protuberance; floor of skull cavity straight; fenestra ovalis not fused with jugular foramen.
