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.
|J. Kříž 2005||Stolidotus with small prosocline shells having prosogyrate umbones located towards the anterior end of shell. On the left (upper) valve well-preserved dorsoventrally elongated mesoconch (Wrigley 1946) with prominent growth bands and furrows. Outer surface sculpture of the left valve composed of numerous flat radial ribs and flat radial gutters broadening ventrally. Main radial ribs are subdivided into halves by the shallow radial gutter. On the inner surface sculpture the main radial ribs are not subdivided and the ribs are coarser along the ventral margin. On adult valves only one radial furrow or sinus developed starting near posterior ventral part of the mesoconch and widening ventrally. Right (lower) valve more convex than left valve, showing wing-like posterior structure. In both valves the outer and inner surface sculptures composed of flat radial ribs and gutters broadening ventrally. In outer surface sculpture of the right (lower) valve the main radial ribs and gutters are subdivided by 2–3 narrow radial gutters.|
