Foraminiferal Biostratigraphy

Planktonic foraminifera are one of the most stratigraphically important groups of organisms for the Cretaceous system. However, standard foraminiferal zonations based mostly on species from the Tethyan bioprovince are hardly applicable in temperate regions where warm-water taxa are scarce or lacking. We propose a foraminiferal zonation based on foraminiferal events recognized in the northern Foraminiferal Transitional Bioprovince, which likely has a high correlation potential at least at a regional scale. Fifteen planktonic foraminiferal zones are distinguished from the upper Albian up to the uppermost Maastrichtian strata in extra-Carpathian Poland and western Ukraine. From the bottom to the top, Thalmanninella appenninica, Th. globotruncanoides, Th. reicheli, Rotalipora cushmani, Whiteinella archaeocretacea, Helvetoglobotruncana helvetica, Marginotruncana coronata, M. sinuosa, Pseudotextularia nuttalli, Globotruncana linneiana, G. arca, Contusotruncana plummerae, Rugoglobigerina pennyi, Globotruncanella petaloidea and Guembelitria cretacea. These zones are calibrated by macrofaunal zonations.

Abstract. A restudy of the planktonic foraminifera at DSDP Leg 90, Site 594, has been made and consequently a revised scheme of late Neogene zones has been necessary. The Globorotalia sphericomiozea Zone (including G. conomiozea) is contracted to occupy a much smaller interval just below the Miocene/Pliocene boundary and the G. puncticulata, G. inflata and G. truncatulinoides Zones have been expanded. In the uppermost Miocene and Lower Pliocene, the standard regional planktonic foraminiferal datums provide a good correlation with DSDP Leg 29 Hole 284, DSDP Leg 90 Hole 593 and with New Zealand on-land palaeomagnetically-zoned sequences. They do not, however, correlate with the magnetochronology adopted in the Leg 90 Initial Reports for this interval in Hole 594 in which Chrons 4–6 are offset downwards against the foraminiferal datums. It is possible that there are unrecognized hiatuses in the Plio-Pleistocene.Higher in the Pliocene, very low species diversity of the cold-water faunas, scarcity of warm-water foraminiferal zonal species, and their much later appearance in Hole 594, contribute to a recognition that the Subtropical Convergence has been an effective barrier against the southwards penetration of most warmer water planktonic species.Neoacarinina blowi Thompson and Globorotalia crozetensis Thompson, are recorded from the New Zealand area for the first time

The article analyzes own data on the species composition of shells of planktonic foraminifera from the Upper Cretaceous sediments of the Indian Oceans, as well as from the sections of the offshore seas of Australia. The species of planktonic foraminifera are grouped and arranged in a climatic series. An analysis of the change in the systematic composition of foraminifers made it possible to distinguish periods of extreme and intermediate climatic states in the Late Cretaceous.

Foraminiferal Biostratigraphy

Planktonic foraminifera are a much used biostratigraphic tool for the subdivision of the Cretaceous System from the Albian upwards. A proposal is given for the recognition of Cretaceous stages, using major biostratigraphic events to mark their boundaries. Thus, the extinction of Globotruncanita calcarata marks the Maastrichtian - Campanian boundary; the extinction of Dicarinel/a asymetrica the Campanian -Santonian boundary; the entry of D. asymetrica the Santonian - Coniacian boundary; the entry of Dicarinella primitiva with Marginotruncana ex gr. renzi -sinuosa the Coniacian -Turonian boundary; the extinction of Rotalipora cushmani the Turonian - Cenomanian boundary; the extinction of Planomalina buxtorfi the Cenomanian - Albian boundary.
