Early 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 کاملPaleontology, paleogeography and Paleoenvironment of the Paleocene benthic foraminiferal species of Plummer in the Tethys; a review
Forty two Paleocene benthic foraminiferal species of the Midway Formation in the Gulf Coastal Plain of Texas, USA were firstly investigated by Plummer (1927), and its paleogeographic distribution in some other countries in the Tethyan province were recorded: North America (USA, Mexico), South America (Argentina), Europe (North Sea Basin, Spain, France, Italy, Czech Republic, Bulgaria), North Af...
متن کاملLate Cretaceous through Neogene Deep - Sea Benthic Foraminifers ( Maud Rise , Weddell Sea , Antarctica ) 1
Upper abyssal to lower bathyal benthic foraminifers from ODP Sites 689 (present water depth 2080 m) and 690 (present water depth 2941 m) on Maud Rise (eastern Weddell Sea, Antarctica) are reliable indicators of Maestrichtian through Neogene changes in the deep-water characteristics at high southern latitudes. Benthic foraminiferal faunas were divided into eight assemblages, with periods of faun...
متن کاملAnomalous shifts in tropical Pacific planktonic and benthic foraminiferal test size during the Paleocene–Eocene thermal maximum
Paleocene–Eocene warming and changes in oceanic hydrography should have significantly impacted the ecology of marine microorganisms, both at the surface and on the seafloor. We analyzed several key characteristics of foraminifera from two Shatsky Rise (ODP Leg 198) cores spanning the P/E boundary including the maximum test diameters of the largest calcareous trochospiral benthic foraminifera an...
متن کاملMacrofaunal Response to the End-triassic Mass Extinction in the West-tethyan Kössen Basin, Austria
Bivalves are the most common macrofauna present in marine sequences spanning the end-Triassic mass extinction and document the initial ecological response to the crisis. In the west-Tethyan Kössen Basin, marine bivalves occur within distinctive low diversity episodic shell beds at the time of initial crisis and d13C minimum, and continue for 1 m (,,20 kyr) upward into the peak extinction phase ...
