Asteroidea - Paxillosida - Astropectinidae
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.
|E. Nosowska 1997||Outer face of marginal ossicles densely covered by tubercles: superomarginal tubercles very small, of equal size; inferomarginal tubercles differentiated into smaller ones, ball- or horseshoe-shaped, and bigger ones, always horseshoe-shaped, spaced in variable number along the abradial margin (at least two at one arm ossicle) and the distal margin; tubercles make a basis for large, strongly flattened scales (the largest are of the length equal to the width of the ossicle they grow on); adambulacrals with relatively long, sharp spines.|
