Planktonic Foraminiferal Assemblage in Surface Sediments from the Thukela Shelf, South Africa

Twenty-three species of planktonic Foraminifera have been identified from surface sediments on the Thukela Shelf (KwaZulu-Natal Bight, South Africa). The assemblage is dominated by Orbulina universa, Globigerinoides ruber and Neogloboquadrina dutertrei, and is referred to the tropical-subtropical zo...

More Information
Summary:Twenty-three species of planktonic Foraminifera have been identified from surface sediments on the Thukela Shelf (KwaZulu-Natal Bight, South Africa). The assemblage is dominated by Orbulina universa, Globigerinoides ruber and Neogloboquadrina dutertrei, and is referred to the tropical-subtropical zone. Surface-water species (Globigerinoides ruber, G. trilobus, G. sacculifer, and G. conglobatus) dominate over deep-water species (Globorotalia inflata, G. tumida, G. menardii, and Sphaeroidinella dehiscens). Identification keys to species of Globorotalia, Globigerina, and Globigerinoides from the KwaZulu-Natal Bight are provided.
