Microfossils, a key to unravel cold-water carbonate mound evolution through time: Evidence from the eastern alboran sea

Stalder, Claudio ; Vertino, Agostina ; Rosso, Antonietta ; Rüggeberg, Andres ; Pirkenseer, Claudius ; Spangenberg, Jorge E. ; Spezzaferri, Silvia ; Camozzi, Osvaldo ; Rappo, Sacha ; Hajdas, Irka

In: PLoS ONE, 2015, vol. 10, no. 10, p. e0140223

Cold-water coral (CWC) ecosystems occur worldwide and play a major role in the ocean's carbonate budget and atmospheric CO2 balance since the Danian (~65 m.y. ago). However their temporal and spatial evolution against climatic and oceanographic variability is still unclear. For the first time, we combine the main macrofaunal components of a sediment core from a CWC mound of the Melilla Mounds...

A new Late Agenian (MN2a, Early Miocene) fossil assemblage from Wallenried (Molasse Basin, Canton Fribourg, Switzerland)

Mennecart, Bastien ; Yerly, Bertrand ; Mojon, Pierre-Olivier ; Angelone, Chiara ; Maridet, Olivier ; Böhme, Madelaine ; Pirkenseer, Claudius

In: Paläontologische Zeitschrift, 2015, p. 1–23

Excavations of two fossiliferous layers in the Wallenried sand- and marl pit produced a very diversified vertebrate fauna. New material allows the reassessment of the taxonomic position of the ruminant taxa Andegameryx andegaviensis and endemic Friburgomeryx wallenriedensis. An emended diagnosis for the second species is provided and additional material of large and small mammals, as well as...

Paleocene–Eocene palaeoenvironmental conditions of the main phosphorite deposits (Chouabine Formation) in the Gafsa Basin, Tunisia

Kocsis, László ; Ounis, Anouar ; Baumgartner, Claudia ; Pirkenseer, Claudius ; Harding, Ian C. ; Adatte, Thierry ; Chaabani, Fredj ; Neili, Salah Mohamed

In: Journal of African Earth Sciences, 2014, vol. 100, p. 586–597

A detailed sedimentary section of the marine Chouabine Formation in the palaeogeographic Gafsa Basin, south-western Tunisia, was investigated in order to characterize environmental and depositional conditions focusing on the interval that spans the Paleocene–Eocene transition. We did stable isotope analyses of bulk sediments. Both phosphorite and carbonate yielded relatively similar isotopic...

Late Weichselian deglaciation and early Holocene development of a cold-water coral reef along the Lopphavet shelf (Northern Norway) recorded by benthic foraminifera and ostracoda

Stalder, Claudio ; Spezzaferri, Silvia ; Rüggeberg, Andres ; Pirkenseer, Claudius ; Gennari, Giordana

In: Deep Sea Research Part II: Topical Studies in Oceanography, 2014, vol. 99, p. 249–269

Cold-water coral (CWC) settlement in northern Norway is strongly related to the outlet-glaciers of the Fennoscandian Ice-sheet, and dating of known CWC structures show clearly post-glacial ages. Two gravity cores (POS391 559/2,277 cm long and POS391 559/3,282 cm long) were recovered on a CWC reef in the area of Lopphavet, northern Norway. Detailed investigations on lithology (sediment structures...

The position of the Rupelian/Chattian boundary in the southern Upper Rhine Graben based on new records of microfossils

Pirkenseer, Claudius ; Berger, Jean-Pierre ; Reichenbacher, Bettina

In: Swiss Journal of Geosciences, 2013, vol. 106, no. 2, p. 291–301

This study analyses the regressive phase of the marine Froidefontaine Subgroup and the subsequent fluvio-lacustrine Niederroedern formation in the southern Upper Rhine Graben during the Late Rupelian and the position of the Rupelian/Chattian boundary. The study is based on the sedimentary record and several microfossil groups from two boreholes, with a focus on new records of fish otoliths,...
