If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

P. M. Galton 1991Twelve cervical vertebrae, centra of posterior third of neck and of the dorsal series are massive so the maximum transverse width is greater than the maximum length; in dorsal vertebrae from posterior two-thirds of series, the solid pedicel-like region is short and the minimum angle between each transverse process and the neural splne is 55°. Sacrum consists of seven coossified centra with two dorsosacral vertebrae anteriorly. Centra of anterior caudal vertebrae are massive and the short neural splnes have massive rounded tops. Anterior process of ilium is short and broadens anteriorly; distal part of ischium tapers and is straight in lateral view. Ratio of maximum lengths of humerus to radius is 1 : 0.69, of humerus to ulna is 1 : 0.79, of femur to humerus is 1 : 0.68, and of femur to ilium is 1: 0.85. Dermal armor includes at least small plates with a thick base, two pair of stocky spines with an expanded base, and four pairs of long caudal spines with a small base (modified from GALTON, 1985).
