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.

A. S. Romer 1947Vertebrae generally rhachitomous; pleurocentra typically paired latero-dorsal structures, never forming complete discs and sometimes lost. Tabular not in contact with parietal. Vomers broad, widely separating internal nares. Laterosphenoid region of braincase completely walled by bone or cartilage. ?No supraoccipital bone. Manus with four digits.
