Sensitivity of the Eocene climate to CO₂ and orbital variability [PDF]

, 2018
The early Eocene, from about 56 Ma, with high atmospheric CO2 levels, offers an analogue for the response of the Earth’s climate system to anthropogenic fossil fuel burning.

High bat (Chiroptera) diversity in the Early Eocene of India [PDF]

, 2007
The geographic origin of bats is still unknown, and fossils of earliest bats are rare and poorly diversified, with, maybe, the exception of Europe. The earliest bats are recorded from the Early Eocene of North America, Europe, North Africa and Australia ...

Life history of the most complete fossil primate skeleton: exploring growth models for Darwinius [PDF]

Royal Society Open Science, 2015
Darwinius is an adapoid primate from the Eocene of Germany, and its only known specimen represents the most complete fossil primate ever found. Its describers hypothesized a close relationship to Anthropoidea, and using a Saimiri model estimated its age ...

Astronomically paced changes in overturning circulation in the Western North Atlantic during the middle Eocene [PDF]

, 2018
North Atlantic Deep Water (NADW) currently redistributes heat and salt between Earth’s ocean basins, and plays a vital role in the ocean-atmosphere CO2 exchange.

Middle Eocene Rhodoliths from Tropical and Mid-Latitude Regions

Diversity, 2020
During the greenhouse conditions prevailing in the early−middle Eocene, larger benthic foraminifers (LBF) spread out on carbonate platforms worldwide while rhodolith beds were scarcely represented.

New records from Banks Island expand the diversity of Eocene fishes from Canada’s western Arctic Greenhouse

Arctic Science, 2018
Eocene vertebrates from the Canadian Arctic, including sharks, bony fishes, turtles, crocodylians, birds, and mammals, have provided strong evidence for relatively warm ice-free conditions in the Arctic during the Eocene Greenhouse interval.
