The Early Toarcian "Oceanic Anoxic Event" (T-OAE) is a very significant paleoenvironmental perturbation of the Mesozoic that coincided with marked disruptions to both the climate system and marine ...

Earth experienced a period of intense, large-scale volcanism during the early Aptian. Around that time, it also experienced widespread ocean deoxygenation during the Oceanic Anoxic Event 1a (OAE1a) as ...

The Early Aptian was a period of profound environmental reorganisation, marked by recurrent episodes of oceanic anoxia that disrupted global biogeochemical cycles. These Oceanic Anoxic Events (OAEs) ...

Researchers analyzed radioisotopes in layers of fossilized volcanic ash. Decay of uranium to lead within tiny crystals enabled scientists to precisely pinpoint dates for certain events. They ...

A series of severe environmental crises in the oceans, spanning 185 to 85 million years ago, significantly altered the course of evolution on Earth. This "tag-team" between the oceans and continents ...

Ocean deoxygenation during the Mesozoic Era was much more rapid than previous thought, with CO2 induced environmental warming creating ocean 'dead zones' over timescales of only tens of thousands of ...
