Ophiocistioidea is a class of extinct echinoderms from the Palaeozoic and early Mesozoic.[2] They most likely form a paraphyletic grade along sea cucumber stem lineage,[3] although some sources still consider the question of ophiocistioid monophyly unresolved.[4]
Ophiocistioidea is named from the Greek words "ophis" (snake) and "kiste" (box).[5]
