Wide-hinged spiriferid brachiopods (below left) have been likened to birds. For example, in China, the common name of such forms translates as 'stone swallows'. There they are boiled in water with various herbs to produce medicinal potions and powders.Silurian - 419 to 444 million years ago. This is the only time that reefs grew in Illinois and Wisconsin. Located south of the equator and in the tropics, this area was covered by clear, shallow, tropical seas. During the Early Silurian, the fossil fauna was dominated by a low-diversity Virgiana pentamerid brachiopod community.

An abundance of borings, as in the case of brachiopod shells from the Vøringen Member, is generally associated with a shallow, oxygenated marine environment; however, individual borings, for example, Rogerella or Conchotrema, can occur in circumlittoral and bathyal Neogene settings (Bromley & D'Alessandro 1990).The internal structure of the dorsal valve of M. haeretica is dominated by strongly developed, pronounced subperipheral ridges, which suggest support for a simple schizolophe type of lophophore, the oldest representative of the highly differentiated, mainly Permian, aulostegoid family Cooperinidae. Abstract: We describe Muhuarina haeretica gen. et sp. …

Brachiopods are the most abundant fossils in Wisconsin. Most people are not familiar with living brachiopods because modern species inhabit extremely deep regions of the world’s oceans, and their shells are rarely found on modern seashores.

The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels. However, from the Cambrian to the Permian (542 to 252 million years ago), another group of organisms called brachiopods dominated the world's oceans. Over 12,000 fossil species of these hinge-valved organisms have been described ... Brachiopods are more closely related to Bryozoans than Mollusks. The easiest differences to identify are in the shells of clams and Brachiopods. Mollusk shells are divided into left and right while Brachiopod shells are divided top (dorsal) and bottom (ventral). The shells of mollusks are usually equal on the right and left. Spiriferid Brachiopod. Brachiopods have one of the longest histories and best fossil records of all invertebrates.

Spiriferida is an order of extinct articulate brachiopod fossils which are known for their long hinge-line, which is often the widest part of the shell. In some genera it is greatly elongated, giving them a wing-like appearance. They often have a deep fold down the center of the shell.
