Paleoecology of the Cretaceous–Tertiary mass extinction in planktonic foraminifera

Age and paleoenvironment of the Maastrichtian to Paleocene of the Mahajanga Basin, Madagascar: a multidisciplinary approach

“…This is consistent with Tethyan shelf regions in general, e.g. Tunisia (Li and Keller, 1998b;Abramovich and Keller, 2002;Keller et al, 2002;Luciani, 2002), Israel (Abramovich et al, 1998), Egypt (Keller, 2002) and Bulgaria , whereas in deep sea environments trochospiral and multiserial taxa tend to be more common (e.g. Keller, 1998a, 1999).…”

Study of Sea level changes with Leckie method of the Abderaz Formation (Middle Turonian-Early Campanian) at type section based on foraminifera

“…1-Epicontinental Sea Forms= ESF : Heterohelix and Guembelitria are related to faunas of shallow epicontinental sea or the border sea (Leckie 1987, PremoliSilva & Sliter 1999, Keller, 2002. 2-Shallow Water Forms= SWF Hedbergella delrioensis and Whiteinella are related to this fauna (Leckie 1987, PremoliSilva & Sliter 1999.…”

Hunting for the 405-kyr eccentricity cycle phase at the Cretaceous-Paleogene boundary in the Aïn Settara section (Kalaat Senan, central Tunisia)

“…The section is accessible and continuous over a thickness of ~100 m. The K-Pg boundary could be followed laterally along the western slope of the small valley over a distance of ~200 m. The K-Pg boundary of the Aïn Settara section has already been the subject of many publications (e.g. MOLINA et al, 1998;ALEGRET et al, 2002;ARENILLAS et al, 2000aARENILLAS et al, , 2000bROBASZYNSKI et al, 2000;DUPUIS et al, 2001;ROBIN et al, 2001;ADATTE et al, 2002;LUCIANI, 2002;PERYT et al, 2002;HENNE-BERT & DUPUIS, 2003;GOOLAERTS, 2010). The survey and sampling carried out cover ~60 m of the section outcropping along the gully slope from the thalweg of the Settara Wadi to the slope top ( Fig.…”

“…ADATTE et al (2002) estimated the value to circa 30-60 m and qualifies the environment as: epicontinental sea, transition between the continental shelf and the slope shelf, or transition between inner and middle neritic. KELLER et al (2002) (MOLINA et al, 2006).…”

“…Some authors considered that the Aïn Settara section was not complete compared with those of El Kef and Ellès (ADATTE et al, 2002;LUCIANI, 2002) because of (1) the presence of burrows under the red clay layer, (2) the low thickness of the P0 planktonic foraminifera zone, (3) the existence, above the red clay layer, of a thin resedimented silt level.…”
