65-Million-Year-Old Primate Fossils Uncovered in Montana

Shortly after the end-Cretaceous mass extinction, the earliest known primates, such as Purgatorius mckeeveri shown in the foreground, quickly set themselves apart from their competition -- like the archaic ungulate mammal on the forest floor -- by specializing in an omnivorous diet including fruit found up in the trees.

Paleontologists in the United States have discovered and analyzed the fossilized remains from two species of Purgatorius, the oldest genus in a group of the earliest-known primates called Plesiadapiformes. Shortly after the end-Cretaceous mass extinction, the earliest known primates, such as Purgatorius mckeeveri shown in the foreground, quickly set themselves apart from their competition — like the archaic ungulate mammal on the forest floor...

This painting depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds. Image credit: Donald E. Davis / NASA.
