This is Mucrospirifer mucronatus(Conrad, 1841), a beautiful spiriferid brachiopodfrom the Silica Shale Formation (Middle Devonian) of Paulding County, northwestern Ohio. I collected it and many others at a quarry on a crisp October day with my friend and amateur paleontological colleague Brian Bade.Flickr photos, groups, and tags related to the "spiriferida" Flickr tag.Megastrophia and Paraspirifer acuminatus are the largest brachiopods in the Devonian Jeffersonville Limestone at the Falls of the Ohio and greater Louisville area, and they are usually between two and three inches wide.

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 …Open-ended tubes were found extending inward from the inner surfaces of brachial valves of three different species of Emsian spiriferid brachiopods. It is believed that these tubes were formed by the outer epithelium of the brachiopods, precipitating shell material around a small commensal filter feeding organism living in the outer mantle cavity.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.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).3 : Brachiopod^microgast ropod biofacies (98/53A) : A = rhynchonellids, B = spiriferid brachiopod; scale bar 2 mm. 4 : Ammonoids from the microgastropod^crinoid biofacies (A^C natural size, D^G U ...Aug 2, 2015 · Spiriferid Brachiopod.

In particular, when the animal relies heav-ily on passive flows, a direct relationship between the shell’s form and the ambient flow over the shell is required (e.g. Wallace & Ager, 1966; Alexander, 1999). In contrast to the declining diversity of brachiopods in recent times, ancient articulate brachiopods flourishedSu Yangzhen & Hou Hongfei 1994.

Fossil spiriferids first appear in the Ordovician period, as illustrated in the fossil range chart for brachiopods. They were extremely diverse during the Devonian period and later went extinct during the Jurassic period. Some fossil brachiopods make spectacular finds, like this one preserved as pyrite (fools gold).

General information on each group, including their appearance, mode of life, and functional role in the reef community is provided on the otheer pages in the Silurian Reef Organisms section. Some of ...The spiriferids are a very variable group of brachiopods. Members of this group can have punctate or impunctate shell microstructure, strophic or astrophic hinge line, and of any of a number of gross shell morphology. Their only defining quality is the presence of a spiral brachidium; that is, a spiral support for the lophophore (spiralia).
