متن کاملEarly Eocene deep-sea benthic foraminiferal faunas: Recovery from the Paleocene Eocene Thermal Maximum extinction in a greenhouse world
The early Eocene greenhouse world was marked by multiple transient hyperthermal events. The most extreme was the Paleocene-Eocene Thermal Maximum (PETM, ~56 Ma), linked to the extinction of the globally recognised deep-sea benthic foraminiferal Velasco fauna, which led to the development of early Eocene assemblages. This turnover has been studied at high resolution, but faunal development into ...
متن کاملTesting the Cenozoic multisite composite DO and DC curves: New monospecific Eocene records from a single locality, Demerara Rise (Ocean Drilling Program Leg 207)
[1] Until recently, very few high-quality deep ocean sedimentary sections of Eocene age have been available. Consequently, our understanding of Eocene paleoceanography has become heavily reliant on ‘‘composite’’ records patched together from multiple sites in different ocean basins and generated using multiple taxa (potential sources of ‘‘local’’ noise in the global signal). Here we test the re...
متن کاملFossil palm beetles refine upland winter temperatures in the Early Eocene Climatic Optimum.
Eocene climate and associated biotic patterns provide an analog system to understand their modern interactions. The relationship between mean annual temperatures and winter temperatures-temperature seasonality-may be an important factor in this dynamic. Fossils of frost-intolerant palms imply low Eocene temperature seasonality into high latitudes, constraining average winter temperatures there ...
