Ammonite - benthic Foraminifera turnovers across the Lower - Middle Jurassic transition in the Lusitanian Basin ( Portugal )
This paper describes and characterises the co-occurrence of ammonite and benthic foraminiferal assemblages across the São Gião outcrop (Central Portugal), a reference section for the Lower-Middle Jurassic boundary in the Lusitanian Basin. The upper Toarcian-lower Aalenian marls and marly-limestones in this section provide a precise and detailed ammonitebased biostratigraphic zonation, with a mi...
متن کاملDistribution and Paleoecology of the Middle Jurassic Foraminifera from Eastern Alborz (Goznawwi section)
Analysis of benthic foraminiferal assemblages was performed in Callovian deposits of the Farsian Formation Northeastern Alborz; Iran. The sequence of Callovian at the Goznawwi area consists mainly of soft marls , which contain high-diversity calcareous assemblages. In this foraminiferal succession nine morphogroups were differentiated according to shell architecture (general shape, mode of coil...

متن کاملIntraspecific stable isotope variability in the planktic foraminifera Globigerinoides sacculifer: Results from laboratory experiments
Laboratory experiments conducted on the multichambered planktic foraminifera Globigerinoides sacculifer are used to determine the effect of symbiont photosynthesis on shell carbon and oxygen isotopic composition. Stable isotope analyses of individual chambers secreted under controlled temperature and light levels show that chamber jl3C values increase with increasing light levels. The effect of...
