Asteroidea - Valvatida - Goniasteridae
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.
|G. Breton 1992||Marginals wider than long and high. External face highly convex to angular. Lateral faces slightly concave, with few scattered pits and a slight sickened external margin. Internal face highly concave, separated from the face of articulation with abactinals (or actinolaterals) by a strong transverse ridge. Intermarginal face frequently divided in two or three faces, which suggest alternating marginals and potential intermarginal plates. Ornament of fine dense granule-pits, slightly projecting in the middle of the external face.|
