Biostratigraphical value of some Strunian (Devonian, uppermost Famennian) Productidina, Rhynchonellida, Spiriferida, Spiriferinida brachiopods

Biostratigraphic significance of brachiopods near the Devonian–Carboniferous boundary

“…Three representatives of the Family Trigonirhynchiidae (characterized by the presence of dental plates and a median septum, septalium covered or uncovered) are selected here. Centrorhynchus (Trigonirhynchiinae according to Nicollin & Brice, 2004) includes medium- to large-sized shells, subpentagonal in outline, with a prominent fold and sulcus, ventral flanks sometimes slightly concave and strong, subtriangular ribs arising at the beaks, and a posteriorly covered septalium. The genus first occurs within the middle Famennian and disappears close to the D–C boundary.…”

“…No genera of the superfamilies Delthyridoidea and Reticularioidea are selected here. The Delthyridoidea underwent a long decline after their acme in the Lower Devonian and became extinct in the Mississippian (Viséan); besides the long-ranging genus Tylothyris (see Nicollin & Brice, 2004), only one new genus ( Texathyris ; presently known only from Texas) appeared during the Tournaisian (top of the Kinderhookian, see Carter, 1991). The evolutionary history of the Reticularioidea is quite similar to that of the Delthyridoidea.…”

“…The purpose of this paper is to refine the biostratigraphic potential of some rhynchonellides, spiriferides, spiriferinides, productidines and strophalosiidines (Brachiopoda) known around the D–C boundary that were previously discussed by Nicollin & Brice (2004). The history of the brachiopods in the aftermath of the Hangenberg Crisis is discussed briefly.…”

“…The latest Famennian (Strunian) brachiopod fauna is known from several places all over the world, e.g., from many local− ities in Europe, Asia, North America, Australia, North Af− rica, and Western Australia (see detailed list and descriptions in Nicollin and Brice 2004; see also Halamski and Baliński 2009). The Strunian brachiopods have a characteristic aspect of a transitional fauna consisting of Devonian (in minority) and Carboniferous (prevailing) forms (Conil et al 1986).…”

“…Shallow and deep−marine organisms, benthos (e.g., corals, bivalves, and stromatoporoids), nekton (ammonoids, placoderms, conodonts), plankton (acritarchs, ostracods) as well as terrestrial ecosystems were severely af− fected (Blumenstengel 1993;Becker 1993;Walliser 1996;Olempska 1997;Głuchowski 2002;Schwark and Empt 2006;Kaiser et al 2006). Nicollin and Brice (2004) summarised that the Strunian brachiopods were represented by 13 genera of Productidina, 7 genera of Rhynchonellida, 13 genera of Spiriferida, and one genus of Spiriferinida.…”
