The evolutionary journey from primitive plesiadapiforms to early primates during the Paleocene and Eocene epochs represents a critical chapter in mammalian history. Fossil records from these ...
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).
If they are right, primates originated right around the boundary between the Cretaceous and the Paleocene – primates probably emerged into a world recently vacated by the non-avian dinosaurs.
A 60-million-year-old fossil initially speculated to be either a Cretaceous metatherian or an Eocene metatherian turned out ...
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 ...
If they are right, primates originated right around the boundary between the Cretaceous and the Paleocene - primates probably emerged into a world recently vacated by the non-avian dinosaurs.
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 ...
In a study described online in the American Journal of Physical Anthropology a team of paleontologists examined dental clues to the diets of so-called stem primates and rodents that roamed North ...
60-Million-Year-Old Fossil Reveals Texas Was Home to Giant Prehistoric Possums Learn more about the discovery of a giant possum in Big Bend National Park and how it’s connected to early primate ...
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.
They say everything's bigger in Texas. And that appears to be true, at least in the case of a group of ancient near-marsupials scientists call Swaindelphys.
