Permian Mass Extinction

Paper Summary:

The extinction-level event that occurred during the Permian period, often known as the Great Dying, forms the boundary between the Permian and Triassic geologic periods. During this time approximately 95 per cent of all marine species died out. This paper presents an overview of this time period and the explanatory theories regarding this event.

From the Paper:

"It has been suggested that this increase in carbon-12 could be the result of upwelling of frozen methane hydrate from the ocean floor. Experiments have shown that a sea temperature rise of 5?C would be sufficient enough to gasify solid methane hydrate. This would lead to huge amounts of greenhouse gases being expelled into the atmosphere, and could have led to the mass extinction ("Permian-Triassic")."
