Asteroidea - Valvatida - Stauranderasteridae
It was assigned to Valvatida by Sepkoski (2002); and to Stauranderasteridae by Spencer and Wright (1966), Villier et al. (2004) and Villier (2010).
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.
