(Table T1) Stratigraphic distribution of phytoliths at ODP Site 188-1165 and 188-1166 sediments (continental slope) ...
Rare phytoliths are described from Late Cretaceous to Quaternary deep-sea sediments from Sites 1165 and 1166, Prydz Bay, East Antarctica. The phytoliths are comparable to modern tree/shrub, grass, and fern forms, although some may be modern contaminants. Spherical tree/shrub phytoliths are the most...
