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. -

Biodiversity Patterns Across the Late Paleozoic Ice Age
Palaeontologia Electronica palaeo-electronica.org Biodiversity patterns across the Late Paleozoic Ice Age Barbara Seuss, Vanessa Julie Roden, and Ádám T. Kocsis ABSTRACT The Late Palaeozoic Ice Age (LPIA, Famennian to Wuchiapingian) witnessed two transitions between ice- and greenhouse conditions. These alternations led to drastic alterations in the marine system (e.g., sea-level, habitat size, sea-surface temperature) forcing faunal changes. To reassess the response of the global marine fauna, we ana- lyze diversity dynamics of brachiopod, bivalve, and gastropod taxa throughout the LPIA using data from the Paleobiology Database. Diversity dynamics were assessed regarding environmental affinities of these clades. Our analyses indicate that during the LPIA more taxa had an affinity towards siliciclastic than towards carbonate environ- ments. Deep-water and reefal habitats were more favored while grain size was less determining. In individual stages of the LPIA, the clades show rather constant affinities towards an environment. Those bivalves and brachiopods with an affinity differ in their habitat preferences, indicating that there might have been little competition among these two clades. Origination and extinction rates are similar during the main phase of the LPIA, whether environmental affinities are considered or not. This underlines that the LPIA marine fauna was well adapted and capable of reacting to changing environ- mental and climatic conditions. Since patterns of faunal change are similar in different environments, our study implies that the changes in faunal composition (e.g., diversity loss during the LPIA; strong increase of brachiopod diversity during the Permian) were influenced by the habitat to only a minor degree but most likely by yet unknown abiotic factors. -

SILURIAN and UPPER ORDOVICIAN ATRYPIDS of the GENERA Plectatrrpa and SPIRIGERINA
NORSK GEOLOGISK TIDSSKRIFT 47 SILURIAN AND UPPER ORDOVICIAN ATRYPIDS OF THE GENERA PLECTATRrPA AND SPIRIGERINA BY A. J. BoucoT & J. G. JoHNSON (Division of Geological Sciences, California Institute of Technology, Pasadena, California, U.S.A.) Abstract. The nomenclatural history of Plectatrypa and Spirigerina is traced and the basis for recognition of each taxon as a valid genus is developed. The earliest progenitors of Spirigerina marginalis, which range from the Upper Ordovician into the Lower Llandovery, are separated as a new subgenus Spirigerina (Eospirigerina), based on Atrypa praemarginalis Savage which is recognized in mid-North America and in Gaspe. The closely related S. (Eospi rigerina) gaspeensis is identified in Britain and Venezuela in the Lower Llan dovery. True Plectatrypa is unknown below the Lower Llandovery; previous citations from the Ordovician are of forms that the writers propose to include in Eospirigerina. A new species, Plectatrypa henningsmoeni, is proposed for a Lower Llandovery form from the Oslo region. Plectatrypa is regarded as an early offshoot of the Atrypinae, off the main line of evolution that resulted in Atrypa in a strict sense and then little differentiated from Eospirigerina, the earliest known member of the Carinatininae. The species and distribution of Plectatrypa and of Spirigerina are listed. Introduction In 1930, ScHUCHERT & CooPER proposed the genus Plectatrypa (1930 p. 278) for a group of sulcate Ordovician and Silurian atrypoids in cluding Atrypa imbricata Sowerby and Atrypa marginalis Dalman and their allies. Until about 1960, the name was commonly used for atrypoids related to imbricata and marginalis, with the exception of the work by PouLSEN (1943), who treated Plectatrypa as a synonym of Nalivkinia Bublitschenko. -

Intense Drilling in the Carboniferous Brachiopod Cardiarina Cordata Cooper, 1956
Intense drilling in the Carboniferous brachiopod Cardiarina cordata Cooper, 1956 ALAN P. HOFFMEISTER, MICHAs KOWALEWSKI, RICHARD K. BAMBACH AND TOMASZ K. BAUMILLER Hoffmeister, A.P., Kowalewski, M., Bambach, R.K. & Baumiller, T.K. 2003 06 12: In- tense drilling in the Carboniferous brachiopod Cardiarina cordata Cooper, 1956. Lethaia, Vol. 36, pp. 107±118. Oslo. ISSN 0024-1164. The brachiopod Cardiarina cordata, collected from a Late Pennsylvanian (Virgilian) limestone unit in Grapevine Canyon (Sacramento Mts., New Mexico), reveals frequent drillings: 32.7% (n = 400) of these small, invariably articulated specimens (<2 mm size) display small (<0.2 mm), round often beveled holes that are typically single and pene- trate one valve of an articulated shell. The observed drilling frequency is comparable with frequencies observed in the Late Mesozoic and Cenozoic. The drilling organism displayed high valve and site selectivity, although the exact nature of the biotic interac- tion recorded by drill holes (parasitism vs. predation) cannot be established. In addi- tion, prey/host size may have been an important factor in the selection of prey/host taxa by the predator/parasite. These results suggest that drilling interactions occasion- ally occurred at high (Cenozoic-like) frequencies in the Paleozoic. However, such anomalously high frequencies may have been restricted to small prey/host with small drill holes. Small drillings in C. cordata, and other Paleozoic brachiopods, may record a different guild of predators/parasites than the larger, but less common, drill holes pre- viously documented for Paleozoic brachiopods, echinoderms, and mollusks. & Brachio- pod, Carboniferous, drilling, parasitism, predation.
