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.
|D. B. Blake and R. Reid 1998||Adult size apparently small, form pentagonal, sides straight to weakly concave. Abactinals tabulate, large relative to disk size, primary circlet ossicles enlarged. Marginals between interbrachial axis and arm tip three in number, very small fourth on largest individuals. Second and third superomarginals abutted along mid-line. Marginals high, outer surface broadly arched, with small, rather widely spaced pustules about 0.25 mm in diameter, these bearing slender spinelets. Pustular groove developed along adradial margin of superomarginals.|
