Reappraisal of the timing of the breakup of Gondwana based on sedimentological and seismic evidence from the Morondava Basin, Madagascar
Abstract The breakup of Gondwana along the former East African Orogen is widely interpreted to have started in the Late Palaeozoic. The present study indicates that the Permo-Triassic or Karoo phaseExpand

Comparison of the Jurassic and Cretaceous sedimentary cycles of Somalia and Madagascar: implications for the Gondwana breakup
The Jurassic and Cretaceous sedimentary history of northern Somalia and the Morondava Basin of south-western Madagascar have been studied. Both regions display an independent facial development;Expand

The messaoudensis-trifidum acritarch assemblage (Ordovician: late Tremadoc-early Arenig) of the Barriga Shale Formation, Sierra Morena (SW-Spain).
The "messaoudensis-trifidum acritarch assemblage" is currently considered to be characteristic of latest Tremadoc-earliest Arenig cold-water environments on the periphery of Gondwana, at highExpand

Upper Permian and lowermost Triassic stratigraphy, facies and ostracods in NW Iran - implications for the P/T extinction event
Ostracod faunas from Upper Permian to Lower Triassic shelf deposits of Northwestern Iran were investigated with re- spect to their stratigraphical range, palaeoecology and extinction patterns. FaunalExpand

Palaeoenvironmental changes in the Late Triassic (Rhaetian) of the Northern Calcareous Alps: Clues from stable isotopes and microfossils
Abstract The Triassic Kossen Formation (Rhaetian) in the Northern Calcareous Alps has been studied with respect to oxygen and carbon isotope ratios of brachiopod shells and whole rocks, together withExpand

Termination of carbonate slope progradation: an example from the Carnian of the Dolomites, Northern Italy
Abstract The demise of carbonate platforms during Carnian time is a widespread phenomenon of the Western Tethys, but the controlling factors are not well-understood. The Dolomites of the SouthernExpand

Middle to Upper Jurassic sedimentary sequences and marine biota of the early Indian Ocean (Southwest Madagascar): some biostratigraphic, palaeoecologic and palaeobiogeographic conclusions
Abstract As part of an intradisciplinary project which was concerned with the early rifting processes between Madagascar and East Africa, the Middle to Upper Jurassic sedimentary sequences of theExpand

Organic carbon isotope values from the Late Permian Seis/Siusi succession (Dolomites, Italy): Implications for palaeoenvironmental changes
Abstract. The Permian-Triassic boundary is marked by a globally prominent negative carbon isotope excursion traceable in marine carbonates and organic matter. In the shallow marine carbonateExpand

Sinuocythere n. gen. (Ostracoda, Limnocytheridae, Timiriaseviinae); a new genus of limnic ostracode from southern Tethyan Middle and Upper Jurassic
A new genus of limnic ostracode, Sinuocythere n. gen., belonging to the family Limnocytheridae, subfamily Timiriaseviinae, and three new species, Sinuocythere subsinuosa n. sp., SinuocythereExpand

Stratigraphic significance of carbon isotope variations in the shallow-marine Seis/Siusi Permian–Triassic boundary section (Southern Alps, Italy)
Abstract. Carbonate carbon-isotope values from the Permian–Triassic (P–T) boundary section at Seis/Siusi (Southern Alps, Italy) show a trend similar to that in numerous other P–T boundary sectionsExpand
