Most prehistoric crinoids attached themselves to a substrate with a flexible, circular, segmented stem. Above the stem food filtering arms extend from a cup-shaped body (or calyx). The stem length and calyx size are species specific, but also vary …The three main sections of a crinoid give it the lily-like appearance. These sections are the segmented column or stem, the calyx where the body cavity and digestion occurs, and the arms which filter food from the environment. Most crinoids live attached to substrate, though there are free swimming species in the fossil record. Crinoids. Home / Common Fossils of Oklahoma / Invertebrate Fossils / Crinoids. Crinoids are echinoderms and are true animals even though they are commonly called sea lilies. The body lies in a cup-shaped skeleton (calyx) made out of interlocking calcium carbonate plates. the arms. Most fossil crinoids have a stem or column that connects the calyx to a holdfast structure. The holdfast may either be a “root” structure that cements to a hard substrate, or an anchor or grappling structure. Other crinoids have cirri that attach to the base of the Calyx that function as legs and permit the crinoid to be free ....
