  • Figure 1. Late Eocene palaeogeographic map showing the studied sites. 1-ODP Leg 198 Shatsky rise (Sites1209B &1212B)
  • Figure 2. Non-Metric Multidimensional Scaling ordination of foraminiferal taxonomic composition (transformed with log x+1) of Bray-Curtis similarity. A- Samples from ODP Site 1209B Shatsky Rise, Pacific Ocean. B- Samples from ODP Site 1212B Shatsky Rise, Pacific Ocean. Colours indicates samples from the three intervals the PETM (Pre-CIE, CIE and Recovery)
  • Figure 3. Non-metric Multidimensional Scaling ordination of foraminiferal traits composition (transformed with log x+1 and total resemblance) of Bray-Curtis similarity. A- Samples from ODP Site 1209B Shatsky Rise, Pacific Ocean. B- Samples from ODP Site 1212B Shatsky Rise, Pacific Ocean
  • Figure 4. Similarity percentage (SIMPER) with traits that contributed to the differences in benthic foraminiferal trait composition across the PETM events in the studied sites (Data cut off 50%).. Grey bars = Pre-CIE; sky blue bars = CIE core; deep blue bars= Recovery
  • Figure 5. Composite trait variations across the three studied sites. The figures show some trait similarities in trait composition across the two oceans. The colour used in a particular modality is uniform across all the sites. The trait abundance below each plot represents the absolute count of traits after standardization. Site location and core depths are plotted at the left-hand corner of the figure and the PETM events at the right
  • Figure 6. Changes in foraminiferal composition of major taxa in the Pacific Sites with core depth (mbsf) and foraminifera bound isotope records. The lithology is mainly foraminiferal oozes. The lithology and δ13C record are those of Takeda and Kaiho (2007) while the morphogroups and taxa curves were created in this study
