Exhibiting good distinct detail allowing the attributes of the crinoid to be studied. A fossil limestone seabed plate encapsulating the exceptionally well-preserved crinoid specimen; Scyphocrinites Elegans sp. A well defined, distinct fossil specimen in all its anatomical attributes, displaying the remarkable articulation of the extinct fossilised marine echinoderm as if laid down only very recently, not aeons ago. Careful conservation of this genuine and authentic fossil limestone plate has enabled the now natural sculptural element to be highlighted.
Exhibiting a fully articulated crinoid crown and stem. The aboral cup or crown, attached to its associated stem or stalk. The stems of some crinoids may have been as much as 50 feet in length on large type Crinoidea. The proximal stem end is attached to the aboral crown cup, the calyx. In the crown or head the arms covered in cilia (feet like feelers), pass food to the mouth situated at the top of the calyx, in this crown the anus is situated next to the mouth, an intestinal tube passes from the mouth in a'U' shaped tract to the annulus, the crinoids food passes through this tract and is digested and exits via the anus opening when the cover over the aboral cup opens to feed.
