Nothing has been found yet to compare with the monstrous eruptions of the later Permian extinction, but some evidence does suggest that volcanism in a large igneous province called the Viluy Traps may have played a ...

During the Permian extinction, the world's oceans began experiencing what is known as euxinia, a phenomenon caused by a combination of high hydrogen sulfide levels and low oxygen levels.The end-Permian mass extinction event (ca. 252 Mya) is the most-severe biodiversity loss in Earth's history and is globally recognized by a rapid negative carbon isotope excursion. The trigger of this event, however, remains controversial. New paired terrestrial and marine compound-specific carbon isotope records may provide clues for this ...“The end-Permian mass extinction may be less well known than the end-Cretaceous, but it was by far the biggest mass extinction of all time.
