The evolutionary journey from primitive plesiadapiforms to early primates during the Paleocene and Eocene epochs represents a critical chapter in mammalian history.

Prior to this discovery, the oldest evidence of stem, or early, primates in the fossil record dated back to the first 300,000 to 500,000 years of the Paleocene (the epoch that followed the Mesozoic).

Tracking primates back to their origin is a thorny task. Scientists have used fossils as well as genetics to try to find the answer, but agreement between the two methods has been elusive. A new ...

The Paleocene-Eocene Thermal Maximum, which occurred about 55 million years ago, was one of the more dramatic climate changes in our earth's history. In the blink of a geological eye (30,000 years ...

A complete lack of undoubted primate fossils from tropical and subtropical regions of the southern continents during the late Cretaceous (98-65 Mya) and Paleocene (65-55 Mya) has traditionally ...

Skeleton shows Mixodectes pungens lived in trees and primarily ate leaves during the Paleocene epoch, highlighting its unique ecological niche after the dinosaurs. Discovering the leaf-eating ...

Everything’s bigger in Texas – including a new species of 60-million-year-old possum. A team of paleontologists from the University of Kansas have discovered a new ancient marsupial in Texas’s Big ...

They’re not, technically speaking, primates, but they're very close to the ancestry of living and fossil primates. These marsupials are probably ecological analogues of early primates.

Modern primates. T. brandti also ... Chester is referring to a 200,000-year global warming event known as the Paleocene-Eocene Thermal Maximum, when temperatures were about 15 degrees Fahrenheit ...
