Global Anoxia Ruled Out As Main Culprit In the P-T Extinction 158
Garin writes "The late Permian saw the greatest mass extinction event of all-time. The causes for this extinction are hotly debated, but one key piece of the puzzle has recently been revealed: while the deep-water environments were anoxic, shallower waters showed clear signs of being oxygenated. This rules out global anoxia, and strongly suggests that other factors, such as the Siberian Traps vulcanism, must have played a dominant role. From the article: 'Rather than the direct cause of global extinction, anoxia may be more a contributing factor along with numerous other impacts associated with Siberian Traps eruption and other perturbations to the Earth system.'

I read anoxia as anorexia.
90% of all species died... but they were looking very stylish right up to that point...

It turns out that the reports of anoxia in the Permian were actually full of hot air.
