The Eocene Epoch was a time of lush forests, steaming swamps, and sprawling open plains. Earth’s climate was warmer, and continents were on the move, forming new land bridges and shifting habitats.

Researchers have sequenced proteins from an ancient rhino relative from the cold, dry Haughton crater site (shown) in the ...

Although Eberle is primarily a mammal paleontologist, she said she now has a new appreciation for sharks after examining their teeth. "They are pretty, they are really interesting," she said.

Proteins degrade over time, making their history hard to study. But new research has uncovered ancient proteins in the enamel ...

The teeth De Vries is working with are up to 56 million years old—they once belonged to the mammals of the late Eocene, Oligocene, and Miocene Epochs and are now preserved in museum and ...

Scientists have shed new light on the rhino family tree after recovering a protein sequence from a fossilized tooth from more ...

The remains of these land-living animals were likely washed into the sea from its shores or down nearby rivers. This means that the remains were often broken up, with teeth now the most common finds. ...

The oldest known evidence of caries in a mammal was found in the fossils of a monkeylike animal that lived 54 million years ago. A shift to higher-sugar foods likely caused the tooth decay, according ...

D’Ambrosia addressed this riddle by examining mammalian teeth from the second warming event that occurred 2 million years later: the Eocene Thermal Maximum 2.

It wasn't until the Eocene that mammals grew larger and expanded their diets from mostly carnivory, insectivory and omnivory to include more species with diets dominated by plants, including fruit.
