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

Biostratigraphy of the Cretaceous/Tertiary boundary in the Sirwan Valley (Sulaimani Region, Kurdistan, NE Iraq)

“…bulbosa Belford, Gublerina cuvillieri Kikoine, Gumbelitria cretacea Cushman. As defined above, the present Biozone CF3 is correlatable with the zone recorded by Li & Keller (1998a,b), Abramovich & Keller (2003) in DSDP Site 525A, Abramovich et al (2002) from Madagascar, Keller et al (1995) Abawi et al (1982) and Abdel-Kireem (1986a); in Italy by Premoli Silva & Sliter (1995 and Premoli Silva et al (1998); in Egypt by Abdel-Kireem & Samir (1995).…”

“…Due to high similarities of foraminiferal occurrence, the present Zone (CF5) is equivalent to that of Li & Keller (1998a,b), Abramovich et al (2002), Samir (2002). It is most likely equivalent to the upper part of the Gansserina gansseri Zone recorded in the North and Northeast of Iraq and different regions of the world by Robaszynski et al (1984), Caron (1985), D'Hont & Keller (1991), Al-Mutwali (1996), Hammoudi (2000), Al-Mutwali & Al-Jubouri (2005), Obaidalla (2005) and it is equivalent to the upper part of the Glt.…”

“…The comprehensive and motif plan in this work was deduced from the planktonic foraminiferal zonation and correlation for the sediments in tropical/subtropical regions, based on the works of Berggren & Miller (1988), Li & Keller (1998a,b), Liu & Olsson (1992), Berggren et al (1995), Berggren & Norris (1997), Olsson et al (2000), Arenillas et al (2000a), Elnady & Shahin (2001), Abramovich et al (2002), Samir (2002), Keller (2002Keller ( , 2004, Abramovich & Keller (2003), Obaidalla (2005), Smit (2005), and Sharbazheri (2007). Fortunately, this zonation has proved satisfactory, with successful results achieved in different localities around the world.…”

“…As defined above, the present Zone CF2 of the studied area is equivalent to the same zone of the P. palpebra Zone of the South Atlantic DSDP Site 525A by Li & Keller (1998a) and Abramovich et al (2002); and of Tunisia by Li & Keller (1998b) and Arenillas et al (2000); eastern Tethys by Keller (2004). The present P. palpebra Zone is equivalent to the upper part of Abathomphalus mayaroensis Zone recorded from different parts of the world -Premoli Silva & Sliter (1995; from Spain: Canudo et al (1991), Molina et al (1996); from eastern Mediterranean: Premoli Silva et al (1998); from USA California: Maestas et al (2003); from Egypt: Luning et al (1998), Elnady & Shahin (2001), Samir (2002), and Obaidalla (2005).…”

Paleoecology & Paleobiogeography of Orbitoides Genus in Zagros Basin (South West Iran)

“…The presence and absence of certain taxa in varying combination noticed in the different regions along the Tethyan corridor is perhaps caused by different habitat confining to shore or deeper photic zone [2]. It has been shown numerically abundant species most often occur at many localities and geographically widespread while less abundant species more often occur at a fewer localities and narrowly distributed [3].…”
