Hypothesis on devonian extinction

The Devonian extinction, occurring around 359 million years ago, is hypothesized to have been caused by a combination of factors, including widespread anoxia in oceanic environments, climatic changes, and possibly asteroid impacts. The disruption of marine ecosystems, particularly affecting reef systems and the diversity of fish species, suggests that changes in sea level and nutrient cycling played significant roles. Additionally, volcanic activity may have contributed to shifts in climate and ocean chemistry, exacerbating the crisis. Overall, it appears that a complex interplay of geological and biological factors led to significant biodiversity loss during this period.
