Actinocrinites
''Actinocrinites'' (from el, ἀκτίς , 'ray' and el, κρίνω 'to perceive') is an extinct genus of crinoids. Fossil records This genus is known in the fossil record from the Devonian period to the Permian period (age range: 360.7 to 290.1 million years ago). Fossils of species within this genus have been found in Australia, China, Europe and United States. Species Species within this genus include: *†''Actinocrinites batheri'' Whidborne 1896 *†''Actinocrinites brouweri'' Wanner 1924 *†''Actinocrinites zhaoae'' Waters et al. 2003 *†''Actinocrinites triacontadactylus'' References Monobathrida Devonian crinoids Carboniferous animals of Europe Prehistoric echinoderms of Europe Mississippian animals of North America Devonian first appearances Permian genus extinctions Carboniferous crinoids Permian crinoids {{paleo-crinoidea-stub ...

Aacocrinus
''Aacocrinus'' is a genus of extinct sea lily Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are ... from the Actinocrinitidae (or Patelliocrinidae) family. It has been shown that it was an attached stationary organism that blindly fed on passing organism. It was composed of Mg calcite and its habitat included the upper-level epifauna. There are currently 14 species within this genus: * '' Aacocrinus acylus'' (Webster & Jell 1999) * '' Aacocrinus algeriaensis'' (Webster, Maples, Sevastopulo, Frest & Waters 2004) * '' Aacocrinus boonensis'' * '' Aacocrinus chouteauensis'' * '' Aacocrinus enigmaticus'' (Webster & Lane 1987) * '' Aacocrinus milleri'' * '' Aacocrinus nododorsatus'' (Bowsher 1955) * '' Aacocrinus protuberoarmatus'' (Missouri) * '' Aacocrinus sampsoni'' * '' Aacocrin ...

Crinoid
Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are members of the largest crinoid order, Comatulida. Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths as great as . Adult crinoids are characterised by having the mouth located on the upper surface. This is surrounded by feeding arms, and is linked to a U-shaped gut, with the anus being located on the oral disc near the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, in most crinoids the five arms are subdivided into ten or more. These have feathery pinnules and are spread wide to gather planktonic particles from the water. At some stage in their lives, most crinoids have ...

Camerata (subclass)
The Camerata or camerate crinoids are an extinct subclass of Paleozoic stalked crinoids. They were some of the earliest crinoids to originate during the Early Ordovician, reached their maximum diversity during the Mississippian, and became extinct during the Permian–Triassic extinction event. Camerates are the sister group of Pentacrinoidea, which contains all other crinoids (including living species). The two largest camerate subgroups are the orders Diplobathrida and Monobathrida. Anatomically, they are distinguished by:Treatise on Invertebrate Paleontology, Volume T. Echinodermata: Crinoidea. Ubaghs et al. Editors: R. C. Moore and C. Teichert. 1978. *fused junctions between the plates of the cup *brachial plates incorporated into the cup *tegmen forming a rigid roof over the mouth *no less than ten and sometimes a very large number of free arms, often pinnulate Subdivisions * Order Cladida? * '' Adelphicrinus'' * '' Eknomocrinus'' * '' Cnemecrinus'' * '' Quechuacrinus' ...
