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.
|M. Borsuk−Białynicka and A. G. Sennikov 2009||A small archosauriform. Cervical centra 12–13 mm in adult length, smaller than in any other known archosauriforms except euparkeriids. From known euparkeriids it differs in having more elongate and cylindrical cervical centra, and costal articulations barely protruding from the body of the centrum, while resembling the East European rauisuchids Tsylmosaurus, Vytshegdosuchus, and Dongusuchus except in smaller size. Weak development of ventral crests makes the vertebrae most similar to those of Tsylmosuchus, but posteroventral obliquity of the centrum is less. In cervicals the centrum length to posterior depth index is about 2.07 except at the transition between cervical and dorsal series where it drops to 1.8. In caudals it ranges from 1.9 to 3.7 and increases down the tail.|
