The underwater crater, spotted serendipitously in commercial observations of seafloor sediments, is believed to have formed at roughly the same time as the famous Cretaceous-Paleogene impact event.
New research supports the hypothesis that dinosaurs were done in by climate change after an asteroid impact kicked up a massive plume of sulfur gases that circled the globe for several decades.
Sediment cores from northwestern China reveal freezing conditions during the Late Triassic killed off many forms of life—but not dinosaurs.
An upward trend in fossilized charcoal indicates that wildfires may have contributed to extinctions during the Great Dying.
On the basis of how much oxygen marine species need and how much is available, researchers predict extinctions comparable to those at the end of the Permian under a business-as-usual emissions scenario.
Un modelo 3D del sistema Tierra incorpora variables como la temperatura y la sulfurización para aclarar el evento de extinción de finales del Pérmico.
A 3D Earth system model incorporates variables such as temperature and sulfurization to shed light on the end-Permian extinction event.
The second-largest mass extinction in Earth’s history took place in a period of stresses from non-sulfidic anoxia in shelf areas, together with glacioeustatic sea-level change and climatic cooling.
Ancient plant and animal DNA buried in Arctic sediments preserve a 50,000-year history of Arctic ecosystems, suggesting that climate change contributed to mammoth extinction.
Volcanic eruptions in what is now western Canada may have triggered a million years of rain and a mass extinction that launched the reign of the dinosaurs.
