Pangea returns in 250 million years, and it’s not looking good for us.
To find the first direct evidence of heightened UV radiation during the end-Permian mass extinction, researchers turned to chemical evidence preserved in pollen grains.
The reconstructed loss of molybdenum during the Toarcian ocean anoxic event suggests deeply anoxic conditions during this time period allowing massive amounts of organic carbon being buried.
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.
