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. B. Blake and D. R. Elliott 2003||Neopalaeasterid-like stem-group asteroid with primary circlet ossicles not significantly enlarged; ossicles rectangular, transversely elongate. ‘‘Extraneous’’ or ‘‘X’’ ossicles not
developed. Carinal series differentiated, ossicles rectangular, transversely elongate, separated longitudinally by gap approximately equal to length of ossicle. Marginal-series ossicles robust, arched, shield-like. Arm margin defined by marginals, adambulacrals in approximately continuous lateral curve. Adambulacrals with ventral-lateral spine fringe. Axillary edges exposed laterally. Enlarged pustule bases absent, small, uniform, discrete pustules present. No granular accessory debris recognized. Ventral surface not exposed in available material.
