The Eocrinoidea ("dawn crinoids") are a paraphyletic division of echinoderms, in that the Blastoids are derived/descended from them. As with all sea lily-like echinoderms, they were sessile animals containing brachioles with a holdfast, and many later developed stalks with their descendants, the Blastoids. The body and in some, the holdfast was covered by plates [1].
