Distribution and taxonomy of Pleistocene radiolarians from KH94-4-AMR-2PC core of the Southern Ocean region

This paper presents first comprehensive account of radiolarian taxa from the Pleistocene sequence of the Antarctic region. On the basis of 54 samples from the piston core KH94-4-AMR-2PC, 71 well-preserved radiolarian species were identified and illustrated. Their systematics, morphological variability and distribution in this Southern Ocean region are given and also compared with similar data available from other regions. Ten new taxa are described in detail but are yet to be formally named. This study provides a more extensive database and new taxa for comparative studies of other parts of the ocean sectors of the Antarctic region.
