[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...

The Eocene rocks in Shabraweet area comprise the Lower, Middle and Upper Eocene stages. Each stage consists of only one rock unit; the Minia Formation, the Mokattam Formation and the Maadi Formation, respectively. The Minia Formation shows angular unconformity relationship with the underlying Cretaceous rocks and disconformity relationship with the overlying Mokattam Formation. The Maadi Format...

[1] Strontium and neodymium radiogenic isotope ratios in early to middle Eocene fossil fish debris (ichthyoliths) from Lomonosov Ridge (Integrated Ocean Drilling Program Expedition 302) help constrain water mass compositions in the Eocene Arctic Ocean between !55 and !45 Ma. The inferred paleodepositional setting was a shallow, offshore marine to marginal marine environment with limited connect...

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 ...

BACKGROUND Discovery of Eocene non-marine vertebrates, including crocodylians, turtles, bony fishes, and mammals in Canada's High Arctic was a critical paleontological contribution of the last century because it indicated that this region of the Arctic had been mild, temperate, and ice-free during the early - middle Eocene (∼53-50 Ma), despite being well above the Arctic Circle. To date, these ...

Using the Max Planck Institute for Meteorology Earth System Model, we investigate the forcing of forests and the feedback triggered by forests in the pre-industrial climate and in the early Eocene climate (about 54 to 52 million years ago). Other than the interglacial, pre-industrial climate, the early Eocene climate was characterised by high 5 temperatures which led to almost ice-free poles. W...

The study of a new specimen of Petrolestes hendersoni from the Eocene Green Formation allows a more precise description of the enigmatic damselfly and the diagnosis of the Petrolestini. Petrolestes messelensis sp. nov. is described from the Eocene Messel Formation in Germany, extending the distribution of the Petrolestini to the European Eocene. The new damsel-dragonfly family Pseudostenolestid...

—The late Paleocene-early Eocene transition was characterized by a long period of global warming that culminated with the highest temperatures of the Cenozoic. This interval is associated with a significant increase in plant diversity in temperate latitudes. However, data from tropical regions remain largely unknown. The record of pollen and spore diversity across the late Paleocene to the earl...

The Hexapodidae was known to date from the Cenozoic of Veneto by Stevea cesarii Beschin, Busulini, De Angeli & Tessier, 1994, from the middle Eocene of Chiampo Valley (Vicenza), and Palaeopinnixa sp. from the upper Eocene of Possagno (Treviso). Recent discoveries from the Eocene of Vicenza area allowed to describe three new genera and four new species of hexapodids. Bellhexapus granulatus n. ge...
