Diagnosis

Reference	Diagnosis
B. Brown 1908	Skull massive, short, and broadly triangular with dermal plates solidly coossified to cartilage bones. Teeth Stegosauroid with ovate-lanceolate flattened crowns and crenulate edges. Vertebre amphiplatyan, solid throughout; neck short, backbone stiff. Body broad, covered with heavy armor plates arranged in rows.
E. A. Maleev 1954 (Syrmosauridae)	Large, four-legged dinosaurs with light defensive armor consisting of individual symmetrically distributed scales. The body is very flat and broad as in the Upper Cretaceous Ankylosauria. The teeth are stegosauroid, with a lamellar flat crown having channeled sculpture [=rugose]. Because of the flat body, the head has a distinctive adaptation for elevating, which is expressed as a unique structure of the cervical vertebrae - the articulation surfaces have been twisted so that the rear surface of the vertebra is depressed below the front surface and is almost parallel to it. The dorsal vertebrae are long, with low centra and are slightly flat at the ends. The torso ribs do not attach to the transverse processes of the vertebrae. The pelvis is stegosauroid. The iliac bones are quite wide and thick in the postacetabular region, as in the Ankylosauria. The sacrum consists of three true sacral vertebrae. The front legs are shorter than the hind legs. The digits end with hoof-like formations (the end phalanges). The tail is long (35-40 vertebrae). The rear tail vertebrae (15-20) are rigidly attached to one another, forming a long "club". The overall length of the skeleton and skull is 4-5 meters.
E. A. Maleev 1956	Ankylosauridae are large quadruped dinosaurs. The cranium is massive, short, and wide, of triangular shape. The top of the cranium is covered with multiple bony plates and spines. The teeth are of stegosaurid type, with oval-lanceolate crown of striated sculpture. The vertebrae are entire on both sides. The neck is short. The sacrum is long, and encloses from five to nine vertebrae. The body is flattened, broad, covered with heavy bony armor, which consists of united bony plates.
T. A. Tumanova 1987	Ankylosaurs with skull greatly expanding in orbital and postorbital regions, width is equal or greater than length (Figs. 2, 3); bones of skull roof covered by many small scutes, which may be posterior to the orbits, change from pyramidal osteoderms into spines; nostrils large and terminal; additional sinuses in nasal cavity present; respiratory tract is flexed; occipital condyle oval, without neck; lateral temporal fenestra and quadrate condyle (except Shamosaurus) closed laterally with osteodermal scutes; scutes also on the the maxilla and expanded from the squamosal into spines; paroccipital processes projects laterally, ends not reaching posterior of skull roof; pterygoid flanges, mandibular branch of pterygoid and ectopterygoid project laterally; teeth are small.
