Crinoidea (crinoids; subphylum Crinozoa; phylum Echinodermata) The most primitive living class of echinoderms, whose members are either stalked (sea lilies) or unstalked (feather stars). The body is contained within a cup-like calyx, composed of regularly arranged plates, consisting of a lower dorsal cup which is covered by a dome (the tegmen ).The topology from well-resolved trees of this early crinoid radiation indicates that the Crinoidea should be subdivided into six subclasses. A new subclass and new order, Aethocrinea and Aethocrinida, respectively, are proposed for crinoids with four circlets of plates in the aboral cup: lintels, infrabasals, basals, and radials.
