Two sectioned or columnar stems support the two crowns, these are delightfully placed within the limestone, seemingly flowing across the plate, as they might have done in life in the devonian period seas. The junction of the stems and crowns is where the brachial plates form the aboral cup, an inverted pyramid structure of plates. fixed in the crown are the arms and feathery pinnules which due to a superb conservation technique are distinct and allow the attributes of the crinoids to be studied.
The fossil plate containing two crinoid individual specimens of the genus Scyphocrinites elegans. These having distinct and excellent anatomical detail, the sea bed limestone plate displays remarkable articulation, as if laid down recently, not eons ago. Careful conservation of this authentic fossil limestone plate has enabled a natural sculptural element to be exhibited.
The aboral cups or crowns, here attached to stems or stalks, the ossicles or articulated stems, science theorises, could have been as much as 50ft long on some large pelagic types. The proximal stem end attaches to the crown (the aboral cup is the calyx). Inside the crown which is the head of the crinoid, the arms were covered in cilia. These cilia have the appearance of feathery arms and passed the food to the mouth (situated inside the arms at the top of the calyx), where also in the crown the anus adjacent to the mouth was also situated.
The crinoids covered over very quickly in some undersea catastrophe millions of years ago, enabling an anoxic environment to persist, which subsequently expedited the process of per mineralization and fossilisation preserving these life forms until their eventual excavation. A rare and remarkable occurrence of the natural world in which we live.
A complex form of animal dating back to the Devonian period. This type scientifically named as the Scyphocrinites elegans crinoid. The 'Scyphocrinites elegans crinoid [Crinoidea] commonly named sea-lily date back to the Paleozoic era, lower Devonian approximately 420 to 380 million years. Although this type is extinct members of the Crinoidea ‘Phylum Echinodermata’ family can still be seen in our oceans today.
