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.
|S. M. Kurzanov and T. A. Tumanova 1978||Occiput and brain case high. Occipital condyle appearing as a narrow oval. On the surface between the condyle and the sphenoccipital protuberances there are two longitudinal, gently sloping elevations that are symmetric relative to the median depression. The floor of the brain case is slightly inflected in the anterior part. The dorsum sellae has a triangular process to the side of the pituitary fossa on the contunuation of the basis trabeculi basalis. The fenestra ovalis lies considerably above the jugular fenestra. The outlets of nerve XII are on the same level.|
|T. A. Tumanova 1987||Occipital condyle a narrow oval and inclined posteroventrally; basioccipital with two elongated, sloping basitubera distributed symmetrically with respect to the ventromedial depression; floor of braincase with few flexions in anterior section; foramen in endocranium large; fenestra ovalis not joined with jugular foramen.|
