“…Porthault (in Donze et al, 1970) recorded this form in the Coniacian and Santonian of southeastern France and has given a new name to it (Hedbergella flandrini). However, since Caron has found it continuously from the Cenomanian to the Santonian, it seems that we are dealing with one and the same species ranging from the upper Albian to the Santonian and showing a slow gradational evolution towards larger and more compressed tests.…”

Cretaceous planktonic foraminifera occur at four sites drilled on Leg 26: on the Broken Ridge (Site 255), in the Wharton Basin (Sites 256 and 257), and on the Naturaliste Plateau (Site 258). In the Wharton Basin only assemblages of Albian age were found. These differ from each other in preservation and in their specific composition. The sequence on the Naturaliste Plateau ranges from upper Albian to Santonian. Rich and well-preserved faunas were found in the Albian, Cenomanian, Coniacian, and Santonian. The main features of all Cretaceous assemblages from this part of the Indian Ocean are the low diversity and the predominance of nonkeeled forms of the genera Hedbergella, Globigerinelloides, Whiteinella, and Archaeoglobigerina. This indicates a cool paleoenvironment for this area during the Cretaceous. Range charts for Sites 257 and 258 are given, and most of the species are discussed in the systematic part of this report.

“…Both Ammonites and planktonic foraminifera are represented. Figure 6 shows the correlations between the standard Ammonite zonation of Sigal (1967) and planktonic foraminiferal zones on the basis of new Ammonite assemblages reported from Southern France (Donze, Porthault et al, 1970;Porthault, in press) and including the recent Ammonite findings in Morocco and Northern Spain (Lehmann, 1962;Wiedmann, personal communication, April, 1972 Donze, Porthault et al, 1970;Porthault, personal communication, June, 1972.

“…However, we are not able to establish exactly the age of the underlying zones. We know that Globotruncana concavata concavata is recorded from layers referable to the Coniacian on the basis of the Ammonite content-more precisely from Early Coniacian of Southern France and of Gabon (Donze, Porthault et al, 1970;de Klasz, 1961)-and that the Globotruncana schneegansi Zone straddles the boundary between the Coniacian and Turonian stages (Porthault, personal communication, April 1972). However, we do not know where the Santonian-Coniacian boundary should be placed with reference to the Globotruncana concavata Zone.…”

Remarks: Globotruncana sigali, G. renzi, G. inornata, Clavihedbergella simplex, Hastigerinoides alexanderi and some species of Globigerinelloides are particularly frequent in this zone. In the upper part some specimens transitional to G. fornicata occur together with G. concavata primitiva. Globotruncana concavata concavata Zone Definition: Interval from the first occurrence of the zonal marker to the first evolutionary occurrence of Globotruncana concavata carinata. Remarks: Most of the species characteristic for the underlying zone become extinct within this zone. G. angusticarinata, G. coronata, G. linneiana, G. lapparenti together with the first representatives of Rugoglobigerina characterize this zone. Globotruncana concavata carinata Zone Definition: Range of the zonal marker. Remarks: This corresponds to the Globotruncana fornicata Zone of Bolli (1957a) and probably to Globotruncana concavata concavata Zone of Barr (1972). G. area has its first occurrence at the base of this zone; G. fornicata is very frequent. G. concavata, G. angusticarinata, G. coronata, Hedbergella delrioensis, Rugoglobigerina pilula do not extend beyond the upper boundary of the zone. No overlap seems to exist with G. elevata and G. concavata group, but this possibility could not be completely excluded because of the poor preservation of the planktonic assemblages of this interval. Globotruncana elevata Zone Definition: Interval with the zonal marker from the first occurrence of the zonal marker to the first occurrence of Globotruncana calcarata. Remarks: In this zone many species have their first occurrence, i.e., G. stuartiformis, Heterohelix pulchra, Pseudoguembelina costulata, Rugoglobigerina rugosa, Globigerinelloides prairiehillensis, and G. yaucoensis. In the uppermost part of the zone G. elevata subspinosa, G. "tricarinata", and Heterohelix punctulata make their first appearance. This zone covers a very long time span. However, we did not find any event to subdivideit. Globotruncana calcarata Zone Definition: Range of the zonal marker. Remarks: Many species have their first occurrence in this zone including G. ventricosa, G. gagnebini, G. subcircumnodifer, G. havanensis, and G. plummerae. "^ ‰ o Earl y ^,. "8-3 Margins= Globotruncana st 2 Globorotalia formosa formosa Zone Definition: Interval with the zonal marker from the first occurrence of Globorotalia aragonensis to the first occurrence of Globigerina taroubaensis. Remarks: The zonal marker is generally not well represented, while G. aragonensis rapidly increases in number. The "spinose-keeled" Globorotaliae and G. soldadoensis group, occurring in the underlying zones, rapidly decrease in abundance while G. intermedia and G. pseudotopilensis become more and more frequent. G. quetra and G. rotundimarginata also occur. The other Eocene zones based on planktonic foraminifera could not be identified in the Caribbean drill sites as this interval yields only very poor foraminiferal assemblages.

“…concavata (Brotzen) in appreciable numbers (Wonders, 1980). According to Porthault (in Donze et al, 1970) the Upper Coniacian-Lower Santonian is recognizable by the presence of Marginotruncana paraconcavata (see also Robaszynski & Caron, 1979). A useful heterohelicid taxon is Gublerina (Sigalia auct.)…”

P. Marks. Integrated Microfossil Biostratigraphy, Mid-Cretaceous (Albian to Santonian). Cretaceous Research (1984) 5, 15-27. An attempt is made to integrate biozones based on planktic Foraminifera with those on calcareous nannofossils, mainly on first order correlation. An approximate correlation with ammonite zones, magnetic events and radiometric age values, partly on first-order data, partly from the literature, is added.
