The water level in the lake has been dropping since early November. My first three Saturday morning trips to the lake yielded few quality finds, So last Saturday I went to a site on the lake where I have found crinoid fossils in the past. I find a lot of crinoidal material at this location, but most of it is very weathered. The site is just above the water line and the weathered rock is covered with mud. So I spent my morning pulling rocks out of the shoreline and washing them in the water. Most of the material was "trash" , but I found several calyxes worth keeping. They are pictured below. Measures approximately 2 inches Measures 1.75 inches Measures 2 inches Measures 2.5 inches Measures 1.75 inches Measures 3 inches Measures 1.75 inches Any help with ID's is appreciated

Archimedes Bryzoan in Matrix Bangor Limestone Formation, North Alabama Mississippian Period c 325,000,000 years ago Archimedes is a genus of bryozoans belonging to the family Fenestellidae. The first use of the term "Archimedes" in relation to this genus was in 1838. This genus of bryozoans is named Archimedes because of its corkscrew shape, in analogy to the Archimedes' screw, a type of water pump which inspired modern ship propellers. These forms are pretty common as fossils but they have been extinct since the Permian. Archimedes is a genus of fenestrate bryozoans with a calcified skeleton of a delicate spiral-shaped mesh that was thickened near the axis into a massive corkscrew-shaped central structure. The most common remains are fragments of the mesh that are detached from the central structure, and these may not be identified other than by association with the "corkscrews", that are fairly common. Specimens in which the mesh remains attached to the central structure are rare. Like other bryozoans, Archimedes forms colonies, and like other fenestrates, the individuals (or zooids) lived on one side of the mesh, and can be recognized for the two rows of equally distanced rimmed pores. Inside the branches, neighbouring individuals were in contact through small canals. Bryozoans are stationary epifaunal suspension feeders. The majority of fossils of this genus are distributed throughout Europe and North America, but they have also been found in sediments of Afghanistan, Canada, Russia, and Australia.

Conostichus - Sea Anemone Burrow Fossils SITE LOCATION: Cedar Creek Lake in Franklin County, Alabama TIME PERIOD: Mississippian Period (ca 350,000,000 yrs old) Data: Conostichus is an ichnogenus of trace fossil. Conostichus was first described as a marine plant by Leo Lesquereaux, a famous paleobotanist (a student of fossil plants) in 1876 from specimens found in southern Illinois. Because of their radial symmetry, however, they have more recently been thought to be molds of crinoids or burrows of sea anemones. Specimens found in place in their enclosing rocks commonly occur in shale beds that include thin strata of fine sand; the cone-shaped structures broaden upward and it is thought that sand collected in the molds or burrows and then became firmly cemented by iron compounds. Shale weathers easily and so the specimens are released. The presence of Conostichus specimens indicates that the rock layers in which they are found were deposited in an ancient ocean. This knowledge can be of practical value because coal beds that are overlain by marine strata commonly are high in sulfur content and therefore may be considered less desirable for use as a fuel. Sea Anemone taxonomy below: (Incertae Sedis) Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: Hexacorallia Family: Actiniaria -

Archimedes with fronds, in Matrix SITE LOCATION: Chesterian Zone of the Bangor Limestone Formation, northern Alabama. TIME PERIOD: Mississippian Period (ca 350,000,000 yrs old) Data: The Archimedes is also termed moss animal, the Bryozoans are colonial animals that live as filter feeders, filtering nutrition from food through it's fenestrae, a screen-like structure that went around the axis of its screw-like central structure seen here. The Bryzoan Archimedes is named after its resemblance to Archimedes’ screw, a device invented by the famous Greek mathematician, engineer, and inventor to raise water above grade. Specimens in which the mesh remains attached to the central structure are rare.

Fifeocrinus Crinoid Arms SITE LOCATION: Chesterian Zone of the Bangor Limestone Formation in northern Alabama TIME PERIOD: Mississippian Period (ca 325,000,000 yrs old) Data: Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). The name comes from the Greek word krinon, "a lily", and eidos, "form". Crinoids are characterised by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, most crinoids have many more than five arms. Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults.

Brachiopods - Composita subquadrata Chesterian Zone of the Bangor Limestone Formation in northern Alabama Mississippian Period (ca 325,000,000 yrs old) Composita is a brachiopod genus that lived from the Late Devonian to the Late Permian. Composita had a smooth shell with a more or less distinct fold and sulcus and a round opening for the pedicle on the pedicle valve. Composita is included in the family Athyrididae (Order Athyridida) and placed in the subfamily Spirigerellinae. The Rhynchonellata is a class of Lower Cambrian to Recent articulate brachiopods that combines orders from within the Rhynchonelliformea (Articulata revised) with well developed pedicle attachment. Shell forms vary from those with wide hinge lines to beaked forms with virtually no hinge line and from generally smooth to strongly plicate. Most all are biconvex. Lophophores vary and include both looped and spiraled forms. Although morphologically distinct, included orders follow a consistent phylogenetic sequence.
