Spiriferid brachiopod.

Network analysis of 14 brachiopod faunas worldwide shows that six groups were detected during the Anisian (Qingyan, southern Qilian – western Qinling, Himalaya – northern Siberia, central Qinghai, New Zealand, and Europe/western Tethys). Compared with those from the western Tethys, the eastern Tethyan faunas are less allied to each other.J. L.

These late Paleozoic phyllite-slate associations occupy a large area, possibly composed of Early Paleozoic sediments in its lower part. The lower levels (Bakirtepe Metaquartzite Member; 0-500 m) and uppermost levels comprise the Duzce Recrystallized Limestone Member (0-25 m). The lower ...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...

Spirifer is a genus of marine brachiopods belonging to the order Spiriferida and family Spiriferidae. Species belonging to the genus lived from the Middle Ordovician ( Sandbian) through to the Late Triassic ( Carnian) with a global distribution. They were stationary epifaunal suspension feeders.

Brachiopods feed on minute organisms or organic particles. Articulate brachiopods, which have a blind intestine, may depend partly on dissolved nutrients.

Sometimes adjectives used with the common name can be very informative.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.Reference: New bizarre micro-spiriferid brachiopod from the Early Carboniferous of China.

Locally, in shallow-marine carbonate deposits these groups can be a major component of shelly faunas, even outnumbering bivalves.Spiriferid Brachiopod. Brachiopods have one of the longest histories and best fossil records of all invertebrates. They lived in the mud or were attached to the sea floor, filter-feeding on organic particles carried by ocean currents. Their fossils are mostly found in muddy sediments, such as the Wandrawandian Siltstone around Ulladulla Harbour.
