Spiriferid brachiopod
Common Fossils of Kansas--Spiriferid and Terebratulid Brachiopods. Hustedia, the three small articulate brachiopods at the top left to center, is classed with the spiriferids on internal features (photo approximately natural size). Note the prominent, even, radiating ridges (plications), the pronounced beak containing the pedicle opening on the ...Hebertellla occidentalis (Hall) – an Ordovician species. Brachiopods are a phylum of bivalves unrelated to clams. They date back to the Cambrian Period and live today. Brachiopods have bilateral symmetry – the left and right side of the shells are mirrors. The top and bottom shells are different.The Emsian/Eifelian boundary occurs within the middle part of the Cultrijugatus Beds, and is constrained because the lower part of the middle Cultrijugatus Beds contains a spiriferid brachiopod fauna that suggests an Upper Emsian age (Avlar and May 1997: 106); whereas the upper part of the middle Cultrijugatus Beds contains …

This seems to agree with Pope’s (1976, p. 176) definition of the Strophomena -type transmuscle septa.Among the brachiopods, the leading role belonged to members of the order Spiriferida, the composition of which was profoundly changed at the superfamily level at the Devonian-Carboniferous boundary: in the Late Devonian, the assemblages were dominated by genera of the superfamily Cyrtospiriferoidea (pl. 4, figs. 1-4), which became extinct at the...Spiriferid brachiopod Lower Devonian Glenerie Limestone Tristates group Eastern NY 1 From the album: Lower Devonian fossils. 28 images; 0 comments; 7 image comments; Photo Information for Complete Acrospirifer.

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.
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). J. L.
