Anoxia duirng the Late Permian Binary Mass Extinction and Dark Matter

TL;DR

This paper explores how a volcanogenic dark matter scenario can explain the binary extinction events and associated anoxia during the Late Permian, addressing limitations of previous models.

Contribution

It demonstrates that the dark matter hypothesis uniquely accounts for both the binary extinction pattern and anoxia in the Late Permian crisis.

Findings

Dark matter scenario explains binary extinction and anoxia

Models fail to account for both phenomena simultaneously

Supports volcanogenic dark matter as a key factor in extinction events

Abstract

Recent evidence quite convincingly indicates that the Late Permian biotic crisis was in fact a binary extinction with a distinct end-Guadalupian extinction pulse preceding the major terminal end-Permian Tartarian event by 5 million years. In addition anoxia appears to be closely associated with each of these end-Paleozoic binary extinctions. Most leading models cannot explain both anoxia and the binary characteristic of this crisis. In this paper we show that the recently proposed volcanogenic dark matter scenario succeeds in doing this.
