The filter-feeding organ of some extinct brachiopods is supported by a skeletal apparatus called the brachidium. Although relatively well studied in Atrypida and Athyridida, the brachidial morphology is usually neglected in Spiriferida. To investigate the variations of brachidial morphology in Spiriferida, 65 species belonging to eight superfamilies were analyzed. Based on the presence/absence ...

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.Spiriferid Brachiopod. Period: Early to Late Mississippian L 40mm (1.6 in.) This ocean-dwelling brachiopod had valves that articulated in an elongated zig-zag pattern, making it look somewhat like a wing. This specimen was collected from the Redwall Limestone which is early to late Mississippian in age (358-325 million years ago).

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...

Brachiopod. Brachiopods ( / ˈbrækioʊˌpɒd / ), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Overview of the Jurassic Period☆ K.N.

This palaeoecological model suggest that, in an environment where the water currents were at least of the order of 0.5 m/s. the spiriferid, anchored to the substrate by its pedicle, flew in the water in much the same way as a kite flies in air.

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).

Brachiopod Fossils. The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels.
