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.

Diagnosis
ReferenceDiagnosis
T. A. Tumanova 1983Ankylosaurids with a tapered forward end of the snout; the anterior wall of the pterygoids slopes gently backward, the pterygoids fuse rigidly with the basisphenoid, the interpterygoidal cavity is small, the quadrate bones fuse with the lower edge of the paroccipital lobes (Fig. I b), the occipital condyle changes from a broad oval to a circular shape.
T. A. Tumanova 1987Ankylosaurids with anterior part of snout narrow; angle of orbital plane with skull axis less than 25°; anterior wall of pterygoids inclined to the rear; occipital condyle wide oval to round; pterygoids fused with basisphenoid; interpterygoid fenestra very small; orbits at midpoint of skull length.
