Foraminifera from Late Pliocene sediments of Heidemann Valley, Vestfold Hills, East Antarctica
The foraminiferal fauna in Pliocene (3.5-2.6 Ma) sediments excavated in a trench 4 m deep, in Heidemann Valley, Vestfold Hills, East Antarctica is examined and described. Sediments accumulated in shallow, fully marine conditions in a glacial valley during the last major glacial event in the Vestfold...
