Tapirs are often called “living fossils” because they have changed very little since the Eocene Epoch, which was between 56 and 33.9 million years ago.

The oldest known fossil of a singing cicada reveals that these insects were making music during the Eocene epoch — long before humans existed. “The fossil has been in the collection of the ...

Millions of years ago, several species of giant birds called "mega penguins" roamed the Earth — and some of them stood taller ...

To garner the results of this study, the research team looked at the impacts of two major asteroids from the late Eocene epoch (about 38 million years to 33 million years ago). One created the 60-mile ...

Researchers have identified 12 ancestral plant species from an early Eocene fossil assemblage in Tasmania that once formed part of a giant, circumpolar forest.

Underwater Paris: The Eocene Epoch About 45 million years ago, during the Eocene Epoch, the area that is now Paris was dramatically different from the big city we know today.

The stumps are remnants of trees that thrived there during the Eocene epoch, when the world was a great deal warmer. Average annual temperatures just 11 degrees from the pole are thought to have ...

Between 34 million to 44 million years ago, an epoch known as the middle-to-late Eocene, Earth's atmosphere transformed drastically.

To better predict how ocean circulation responds to greenhouse gas-driven global warming, the research team looked to the early Eocene epoch, between roughly 49 and 53 million years ago. Earth then ...

Foraminifera shells helped scientists piece together a picture of ocean movement during the Eocene period, where high atmospheric carbon levels caused the exchange of ocean waters to slow down ...

Climate Change During the Eocene Epoch Kirk’s research also shows that during the late Eocene, forests became more fragmented because of climate change, and primates started to evolve in isolation ...
