    Late Devonian (Frasnian) bivalves from the Nocedo Formation – the results of Wilhelm Kegel’s 1927 field trip to northern Spain Michael R.W. Amler Amler, M.R.W. Late Devonian (Frasnian) bivalves from the Nocedo Formation – the results of Wil- helm Kegel’s 1927 field trip to northern Spain. Scripta Geologica Special Issue, 7: 13-34, 9 figs., Leiden, December 2010. Michael R.W. Amler, Department für Geo- und Umweltwissenschaften, Sektion Geologie, and Geo- Biocenter Munich, Ludwig-Maximilians-Universität München, Luisenstr. 37, D-80333 München, Ger- many ([email protected]), and Institut für Geologie und Paläontologie im Fachbereich Geographie der Philipps-Universität Marburg, Hans-Meerwein-Str., D-35032 Marburg, Germany ([email protected]). Key words — Bivalvia, Rhenish Facies, Nocedo Formation, Frasnian, Cantabrian Mountains, Iberia, Wilhelm Kegel. During a field trip to the Peña-Corada Unit of the southernmost Esla region of the Cantabrian Moun- tains in 1927, the German stratigrapher Wilhelm Kegel sampled brachiopods and bivalves from a section in the Laoz valley near La Ercina. The stratigraphic position is believed to be part of the No- cedo Formation of Frasnian age. This fauna includes poorly preserved steinkerns of a near-shore bi- valve fauna that was prepared for publication including labels and proposed names, but never pub- lished. The fauna represents only a very small and random part of the former community. But as in- formation on Frasnian bivalves is scarce, the few specimens add important information on the distri- bution and palaeogeographic occurrence of near-shore, that is, Rhenish Facies bivalves within the south Laurussian – Rheic Ocean Realm.

  • Brachiopods from the Mobarak Formation, North Iran
    GeoArabia, 2011, v. 16, no. 3, p. 129-192 Gulf PetroLink, Bahrain Tournaisian (Mississippian) brachiopods from the Mobarak Formation, North Iran Maryamnaz Bahrammanesh, Lucia Angiolini, Anselmo Alessandro Antonelli, Babak Aghababalou and Maurizio Gaetani ABSTRACT Following detailed stratigraphic work on the Mississippian marlstone and bioclastic limestone of the Mobarak Formation of the Alborz Mountains in North Iran, forty-eight of the most important brachiopod taxa are here systematically described and illustrated. The ranges of the taxa are given along the Abrendan and Simeh Kuh stratigraphic sections, located north of Damgham. The examined brachiopod species date the base of the Mobarak Formation to the Tournaisian, in absence of age-diagnostic foraminifers. Change in brachiopod settling preferences indicates a shift from high energy, shallow-water settings with high nutrient supply in the lower part of the formation to quieter, soft, but not soppy substrates, with lower nutrient supply in the middle part of the Mobarak Formation. Brachiopod occurrence is instead scanty at its top. The palaeobiogeographic affinity of the Tournaisian brachiopods from North Iran indicates a closer relationship to North America, Western Europe and the Russian Platform than to cold-water Australian faunas, confirming the affinity of the other biota of the Alborz Mountains. This can be explained by the occurrence of warm surface-current gyres widely distributing brachiopod larvae across the Palaeotethys Ocean, where North Iran as other peri- Gondwanan blocks acted as staging-posts. INTRODUCTION The Mississippian Mobarak Formation of the Alborz Mountains (North Iran) has been recently revised by Brenckle et al. (2009) who focused mainly on its calcareous microfossil biota and refined its biostratigraphy, chronostratigraphy and paleogeography.
