Now researchers have confirmed that an ancient dolphin that lived during the Oligocene Epoch — 33.9 million to 23 million years ago — was the first cetacean (a type of mammal) using ...

A team of researchers studying 22.5-million-year-old spider fossils from Aix-en-Provence were taken aback when the petrified pests glowed under a fluorescent microscope.

Some 30 million years ago, during what’s known as the Oligocene Epoch, a leopard-like hypercarnivore—that is, an animal whose diet is at least 70 percent meat—stalked the lush forest of ...

In a rare find, a team of scientists in Egypt uncovered a nearly complete skull that offers insight into a not-before-discovered apex predator species that lived 30 million years ago.

In an ancient temperate forest in what is now Oregon, an insect dug deep into a sandy bank near a creek. There, in a damp burrow, she laid dozens of oblong eggs, about 50 in all. Despite her ...
