“…Despite its insufficient and limited aspect, the faunas described here show some similarities (at least at the generic level) with assemblages described elsewhere in the world, particularly in the North of France (Brice 1988) or Belgium (Mottequin 2008). Apart from its ubiquitous elements, the content of this fossil assemblage as a whole indicates strong affinities with West European faunas, either of Laurussian (e.g.…”

Two new sections in the Eastern Taurides, Turkey, have yielded brachiopods and crinoids of Middle-Late Devonian age. Fifteen brachiopod species, among them two are new (Paillettia menae sp. nov. and Eodmitria sezgini sp. nov.) and three crinoid species have been identified. A late Givetian to early Frasnian age has been established for these sections based on the brachiopods, whereas crinoids rather indicate a late Givetian age. This fossil assemblage reflects strong affinities with Gondwanan and peri-Gondwanan domains.•

“…Generally, the studied material is inadequate in quality and quantity to provide a basis for a detailed description and taxonomic determination. It shows some external similarity to A. bayeti Rigaux, 1908 as redescribed by Brice (1988) from the Frasnian Ferques Formation of the Ferques area (Boulonnais, France).…”

ABSTRACT:Baliński, A., Racki, G. and Halamski, A. T. 2016. Brachiopods and stratigraphy of the Upper Devonian (Frasnian) succession of the Radlin Syncline (Holy Cross Mountains, Poland). Acta Geologica Polonica, 66 (2), 125-174, Warszawa.The lower part of the Frasnian succession in the Radlin Syncline (Kielce-Łagów Synclinorium, southern region of the Holy Cross Mountains), in the two studied successions: Józefka at Górno and (for the first time) Radlin, consists of the rhythmic marly Szydłówek Beds, the fossil-rich limestones of the Wietrznia Beds (locally) and the atypically developed, calcareous Kostomłoty Beds. The carbon isotope chemostratigraphic pattern overall corresponds well to the global Early-Middle Frasnian biogeochemical perturbation, even if the major punctata positive excursion is only fragmentarily recorded in the Kostomłoty intrashelf basin.Two brachiopod assemblages are abundantly represented in both sections: the Phlogoiderhynchus polonicus Assemblage, typical of the Szydłówek Beds, and the Biernatella lentiformis Assemblage, limited to the middle part of the Wietrznia Beds. Both are highly dominated by the index species. Twenty nine lower Frasnian brachiopod species (Craniida -1 species, Strophomenida -1, Productida -2, Protorthida -1, Orthida -5, Pentamerida -1, Rhynchonellida -4, Atrypida -4, Athyridida -3, Spiriferida -4, Spiriferinida -3) are described from the Szydłówek Copper, 1996 and is the youngest known representative of the suborder Davidsonioidea Copper, 1996. Skenidioides cretus Halamski sp. nov. is the last representative of the genus. Statistical investigation of a large sample of Spinatrypina (Exatrypa) explanata did not confirm the existence of two dimorphic forms, coarse-and fine-ribbed.The high-diversity Biernatella lentiformis Assemblage is quite dissimilar to coeval brachiopod assemblages described heretofore from the Holy Cross Mountains region. It is interpreted as consisting of mostly parautochthonous dwellers of deep-slope muddy habitats and a local, occasionally storm-agitated, intra-basin brachiopod-crinoid-coral shoal. The fauna was adapted probably to cooler and nutrient-poor waters during an initial phase of the severe carbon cycle perturbation.

“…Many of the internal and external characters mentioned by Paeckelmann (1942) and Brice (1988) in their descriptions of syringothyriformis are to be found in other varieties of verneuili, as well as in other cyrtospiriferid species. This is particularly the case for the occasional presence of slight asymmetry of the shell, and ventral flanks near the cardinal extremities being slightly concave to flat.…”

“…Therefore, statements such as "le type décrit par Murchison" (Brice in Joseph et al, 1980, p. 36) or "On peut regretter que Murchison ait choisi de figurer, comme type de l'espèce, un spécimen gérontique" (Brice, 1988, p. 365) are not justified.…”

ABSTRACT. 'Spirifera disjuncta' Soverby, J. de C in Sedgwick &Murchison, 1840 and 'Spirifer Verneuili' Murchison, 1840 were declared synonyms in 1840. 'Spirifera disjuncta' is based on a type series consisting of moulds of three specimens from the Upper Devonian of England: one from the Strunian of Barnstaple, North Devon, and two from the upper Famennian of Petherwin, North Cornwall. The type series of 'Spirifer Verneuili' is composed of three specimens from the Frasnian of Boulonnais, France. Lectotypes are designated herein. The acceptance of the synonymy of the two species, which still prevails, is considered unjustified. KEYWORDS:
