The end-Triassic extinction along with the end-Permian and end-Cretaceous events are the most severe mass extinctions in the past 270 million years. The...
The El Niño-Southern Oscillation, which is characterized by irregular alternations between anomalously warm (El Niño) and cold (La Niña) conditions,...
Carbonate minerals are of particular interest in paleoenvironmental research as they are an integral part of the carbon and water cycles, both of which...
Breakup of an asteroid passing within Earth’s Roche limit likely formed the debris ring during the middle Ordovician period, according to new research...
The end-Permian mass extinction, which occurred about 252 million years ago, was the most severe extinction event in the past 540 million years, eliminating...
Using a large assemblage of human fossils from Ice Age Europe, paleoanthropologists have identified a population turnover in Western Europe at 28,000 years...
Yellow crystals of elemental sulfur were revealed after NASA’s Curiosity rover happened to drive over a rock and crack it open on May 30, 2024, according...
In a new study, planetary scientists found strong similarities between soils found in Gale Crater on Mars and those of Canada’s Newfoundland, a cold...
Fossil and molecular evidence suggests that complex multicellular organisms originated and proliferated during the Neoproterozoic Era (1,000-541 million...
Cold, dense clouds in the interstellar medium of our Milky Way Galaxy are around four-five orders of magnitude denser than their diffuse counterparts....
A fundamental question in dinosaur evolution is how they adapted to long-term climatic shifts during the Mesozoic Era (the dinosaur era lasting from 230...
Archaeologists from Macquarie University and Polish Academy of Science’s Institute of Mediterranean and Oriental Culture have discovered 16 new rock...
Bergmann’s rule is a scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer...
Paleontologists have examined a large assemblage of dinosaur tracks and fossilized plants from the Nanushuk Formation, which crops out over much of the...
