Isocrinida

	Isocrinida Isocrinida is an order of sea lilies which contains four extant families. Characteristics Members of this order are characterised by having a "heteromorphic" stalk; the stalk consists of a series of nodes with cirri, interspersed by several nodes without cirri. There are additionally a whorl of cirri at the base on which the animal perches. The calyx is a shallow cup consisting of five basals and five radials.

	Articulata (Crinoidea) Articulata are a subclass or superorder within the class Crinoidea, including the only living crinoid species. They are commonly known as sea lilies (stalked crinoids) or feather stars (unstalked crinoids). The Articulata are differentiated from the extinct subclasses by their lack of an anal plate in the adult stage and the presence of an entoneural system. Articulata first appeared in the fossil record during the Triassic period although other, now extinct crinoid groups, originated in the Ordovician. Characteristics Articulata exhibit pentamerous symmetry. The stalk, which consists of numerous disks held together by ligaments, supports a calyx or cup made of circlets of calcerous plates. In Comatulids, the stalk develops following the larval stage, but the juveniles shed all but the topmost disk to take up a free-living existence. Five often branched arms, which consist of articulated series of Ossicle (echinoderm), ossicles, extend from the oral plate and form the food-capture ...

	Endoxocrinus Parrae ''Endoxocrinus parrae'' is a species of stalked crinoids of the family Isselicrinidae. It is the most commonly found isocrinine species in west Atlantic Ocean. Morphology As members of the order Isocrinida, ''E. parrae'' possess a heteromorphic stalk that is made of calcareous nodal columns. Their body is mostly made of porous ossicles, with minimal soft tissue connecting the calcareous structure. The stalks can measure 50.5 cm in some subspecies, but average between 10.2 cm and 23.5 cm. The stalks average between 4–5mm in diameter, and are connected to between 23 and 58 feeding arms that branch off radially around the mouth and anus. While some subspecies of ''E. parrae'' possess arms with a smooth dorsal surface, others have been shown to exhibit a serrated dorsal surface, while others have shown morphology that is between the two characteristics, not quiet smooth but not fully serrated.

	Anisian First Appearances In the geologic timescale, the Anisian is the lower stage or earliest age of the Middle Triassic series or epoch and lasted from million years ago until million years ago. The Anisian Age succeeds the Olenekian Age (part of the Lower Triassic Epoch) and precedes the Ladinian Age. Stratigraphic definitions The stage and its name were established by Austrian geologists Wilhelm Heinrich Waagen and Carl Diener in 1895. The name comes from ''Anisus'', the Latin name of the river Enns. The original type locality is at Großreifling in the Austrian state of Styria. The base of the Anisian Stage (also the base of the Middle Triassic series) is sometimes laid at the first appearance of conodont species '' Chiosella timorensis'' in the stratigraphic record. Other stratigraphers prefer to use the base of magnetic chronozone MT1n. There is no accepted global reference profile for the base, but one ( GSSP or golden spike) was proposed at a flank of the mountain Deşli Caira in the Roma ...

	Metacrinus Rotundus ''Metacrinus rotundus'', the Japanese sea lily, is a marine invertebrate, a species of stalked crinoid in the family Isselicrinidae. It is a species found off the west coast of Japan, and is living near the edge of the continental shelf, around 100–150m deep. This is the shallowest species among the extant stalked crinoids. Description In appearance, the Japanese sea lily resembles a feather duster. It has a central mouth surrounded by a crown of many-branched feeding arms. These are jointed and can coil up or unroll to expose the feathery pinnules on either side to the current. Each pinnule has several rows of tube feet and a central ambulacral groove that leads to a groove on the arm that continues down to the mouth. The crown is supported by a tough stalk composed of calcareous ossicles bound together by ligaments. At the base of the stalk is a disc-like sucker and the sides of the stalk bear five whorls of cirri (clawed appendages). The stalk continues lengthening dur ...
