“…-The stratigraphic range of the genus Kosagittella occupies the Ludlow to the Eifelian. At present, the genus is known only from the Barrandian area (Mergl 2001(Mergl , 2009Mergl & Ferrová 2009;Mergl & Vodrážková 2012). There is a succession of several species, with the earliest K. clara Mergl, 2001 (Ludlow), followed by K. pinguis Mergl, 2001 (Lochkovian), K. lingua (Barrande, 1879) (Pragian), K. robusta sp.…”

“…Specimens sampled in the Chýnice Limestone (upper Emsian) were left in open nomenclature (Mergl & Ferrová 2009). Other poorly preserved specimens sampled in the Třebotov Limestone (upper Emsian, P. serotinus Zone) were referred to P. pulsatilla (Mergl & Vodrážková 2012). Generic identification of the shell fragments is rather easy due to the characteristically pitted exterior of shell and the surface of dorsal propareas (Mergl & Ferrová 2009, fig.…”

“…K. pulsatilla has a thinner shell wall, with correspondingly weaker impressions of muscle scars, pallial markings and the visceral area. Specimens figured by Mergl & Vodrážková (2012) were referred to K. pulsatilla. The first of three figured specimens (Mergl & Vodrážková 2012, fig.…”

Lingulate brachiopod fauna from Suchomasty Limestone (upper Emsian, P. serotinus Zone) are examined. Eleven species were observed, of which Kosagittella robusta, Chynithele intermedia, Lochkothele rugellata and Praeohlertella lukesi are described as new taxa. Associated Opatrilkiella kobyla, Havlicekion frydai and Opsiconidion coralinus were described previously from the Chýnice Limestone of the Barrandian area. Four taxa are left in open nomenclature including further evidence of the siphonotretid Orbaspina in the upper Emsian. The composition of the fauna shows distinct difference to other Emsian and Eifelian lingulate brachiopod faunas of the Koněprusy area of the Barrandian. •

Lingulate brachiopods from the Lampazar Formation (late Cambrian) of the Cordillera Oriental of northwestern Argentina

et al. 2015

The Angosto de Lampazar, a classic locality for the study of lower Paleozoic successions in the Cordillera Oriental, NW Argentina, has yielded a late Cambrian relatively diverse, lingulate brachiopod fauna. Sandy lenses with calcareous cement from the uppermost levels of the Lampazar Formation have yielded abundant remains of articulate and phosphatic brachiopods. Among the latter, the new speciesEurytreta harringtoniMergl and Herrera,Lingulella?melonicaMergl and Herrera,Libecoviella lenticularisMergl and Herrera, andSchizambon cardonalisMergl and Herrera, as well as the new genus and speciesSaltaia lampazarensisMergl and Herrera are formally introduced. Trilobites and conodonts from the same horizons characterize theCordylodus proavusZone, allowing a correlation with Stage 10 of the Furongian Series. Although the information on lingulate brachiopods from theC.proavusZone is scarce across the world, the composition of the studied association displays a relationship with coeval and slightly younger faunas of Utah and Kazakhstan. The Argentine brachiopods, the first described from the late Cambrian Proto-Andean margin of Gondwana, are more closely related to temperate Laurentian faunas than to those from the high latitude North African margin of Gondwana.

Byronids are problematic fossils of possible cnidarian affinity, only rarely reported from the Devonian, but never previously studied in the Barrandian area, Czech Republic. Two new species Prestephanoscyphus branzovensis sp. nov. and Prestephanoscyphus robustus sp. nov. are erected from the Lochkovian and the Eifelian, respectively. Four poorly known species referred to Byronia are described in open nomenclature from the Emsian and Eifelian. The new genus Parabyronia gen. nov. with the type species Parabyronia elegans sp. nov. is closely related to other sphenothallids but is distinguished by transverse ridges on its theca and short spines at the apertural end of the theca. Definite identification of phosphatic rings as the attachment structure of byronids was proved by new material of the Lochkovian age. A dwarf conularia Pidiconularia gen. nov. with the type species Pidiconularia tubulata sp. nov. is remarkable by its minute size and very fine ornament; its conulariid affinity is proved by subrectangular cross-section and four internal carinae. Microstructure of theca of Prestephanoscyphus is characterised by alternation of compact laminae of aligned columnar microcrystallites and chambered laminae with isometric microcrystallites of apatite. Accretionary growth of byronid theca and structure of the holdfast with basal opening for the adhesive pedal disc support their cnidarian affinity although they likely display the bilateral instead of tetramerous symmetry. The protective function of bilaterally symmetrical whorls of internal apophyses in Prestephanoscyphus is suggested and their role in strengthening of thecal wall or supporting function of gastric septa are disputed. The byronids are regarded as epibionts rather than attached to the rocks. They are representatives of benthic groups with phosphatic shells that declined with decreasing availability of phosphorus in seas and oceans.
