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.
|D. H. Erwin et al. 2011||Oval-shaped, bilaterally symmetrical fossils composed of several morphologically distinct and concentrically-arranges zones. Outermost zone is typically smooth and crenulated, while innermost region is bordered by thin transverse wrinkles and contains a deep longitudinal invagination in the center. The anterior end is narrower and appears to house a retractable, arrow-shaped structure presumed to be responsible for the fan-shaped scratch marks (i.e. Radulichnus) sometimes associated with Kimberella.|
