A new analysis of exquisitely preserved laminated rocks (varves) from the Port Askaig Formation on the Garvellach Islands, Scotland, shows that climate...
Shorebirds are widespread birds whose dependence on coastal and wetland environments makes them effective paleoenvironmental indicators. Wading shorebirds...
New research challenges conventional wisdom by demonstrating that mid-ocean ridges and continental rifts, not volcanic eruptions, played the central role...
NASA’s Perseverance rover has discovered several thousand small, light-toned rock fragments, or float rocks, with some exhibiting spectral signatures...
Severe and persistent river droughts, each lasting longer than 85 years, affected the Indus basin between 4,400 and 3,400 years ago, according to new research....
Researchers have discovered 6-million-year-old-ice and air in shallow ice cores drilled in the Allan Hills region of East Antarctica. They speculate that...
A new genus and species of theropod dinosaur being named Anteavis crurilongus has been described by a team of paleontologists from the Universidad Nacional...
A small, isolated population of common hippos (Hippopotamus amphibius) was present in the Upper Rhine Graben in southwestern Germany during the middle...
New research introduces a paleoenvironmental model in which tidal dynamics influenced the earliest development of agriculture and sociopolitical complexity...
Textbooks often portray primates as originating, evolving, and dispersing exclusively within warm tropical forests. This tends to come from fossil evidence...
During the Paleocene-Eocene Thermal Maximum (PETM), a period of geological rapid warming and aridification approximately 56 million years ago, a flesh-eating...
During periods known as Snowball Earth, between 720 and 635 million years ago, early eukaryotes — complex cellular lifeforms that eventually evolved...
In new research, paleontologists combined data on the distribution of Triassic pterosauromorph (pterosaur + lagerpetid) fossils with information on the...
Today, there are only two sloth species, but historically, there were dozens of them, including one with a bottle-nosed snout that ate ants and another...
The genus Tyrannosaurus most likely arose in North America, although its direct ancestors migrated over from Asia more than 70 million years ago, according...
Observations of large valley networks on today’s Mars suggest formation by flowing water. However, most climate models cannot sustain temperatures above...
The Saharo-Arabian Desert is one of the largest biogeographical barriers on Earth, impeding dispersals between Africa and Eurasia, including movements...
Called ferrihydrite, this iron mineral formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current...
As our Solar System orbits the Milky Way, it encounters various environments, including dense regions of the interstellar medium. These encounters can...
