A new analysis of exquisitely preserved laminated rocks (varves) from the Port Askaig Formation on the Garvellach Islands, Scotland, shows that climate...
Mars almost certainly once held abundant water. Until now, observations have shown that most atmospheric water loss occurs during the Red Planet’s southern...
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...
Researchers have found ancient gases and fluids trapped in 1.4-billion-year-old halite crystals from northern Ontario, Canada. Their analyses directly...
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...
While banning ozone-destroying gases such as CFCs has helped the ozone layer to recover, when combined with increased air pollution the impact of ozone...
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...
Scientists with the Wildlife Conservation Society have documented a remarkable diversity of wildlife visiting the artificial watering holes in Guatemala’s...
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...
Slope streaks are dark features on Martian slopes that form spontaneously and fade over years to decades. Some planetary scientists have interpreted those...
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...
