Where: Antarctica (63.3° S, 136.0° E: paleocoordinates 63.9° S, 132.7° E)
• coordinate stated in text
When: Early/Lower Eocene (55.8 - 48.6 Ma)
• The lowermost 110 meters of sediments recovered at IODP Site U1356 (895.5 to 1000.08 meters below sea floor [mbsf], lithostratigraphic Units X and XI) are dated as Early to Middle Eocene in age based on the integration of dinoflagellate cyst (dinocyst) biostratigraphy and magnetostratigraphy (Expedition 318 Scientists. Site U1356. in Escutia, C., Brinkhuis, H., Klaus, A., and the Expedition 318 Scientists. Proc. IODP 318 (2011)).
Environment/lithology: shallow subtidal; silty claystone and sandstone
Size class: microfossils
Preservation: original sporopollenin
Collected by IODP
Collection methods: core, chemical, hydrochloric, hydroflouric,
• This research used samples and data provided by the Integrated Ocean Drilling Program (IODP).
•
•A total of 145 palynological samples, taken from the Eocene interval of Site U1356 at a resolution of 20-30 cm, were processed using identical protocols at the Institute of Geosciences of Goethe University Frankfurt and the Laboratory of Palaeobotany and Palynology of Utrecht University.
