This paper places the blame for…
Hmmm. This sounds a bit like a sales pitch against “dirty coal” in support of the recent EPA Mercury ruling instead of regular geological research. I question this research claim because they only have evidence that there were spikes of Mercury during those events, not that they caused or accelerated the extinctions. The PR states:…
Algae and bacteria hogged oxygen after ancient mass extinction, slowing recovery of marine life, say Stanford researchers After the biggest mass extinction in Earth’s history – 250 million years ago – algae and bacteria in the ocean rebounded so fast that they consumed virtually all the oxygen in the sea, slowing the recovery of the…
