Asteroidea - Valvatida - Radiasteridae
It was assigned to Paxillosida by Sepkoski (2002); to Radiasteridae by Blake and Reid (1998), Blake and Jagt (2005) and Blake and Reboul (2011); and to Astropectinidae by Gale (2011).
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||Radiasterid with relatively large, transversely elongate marginals; distal marginals particularly suggestive of those of Astropecten. Inferomarginals with well-developed lateral spine fringe. Actinals with elongate, slender, conical spines. Adambulacral furrow spines about 5; many elongate, slender spines on actinal surface. Madreporite large, near disk center, not partially covered by paxillae.|
