Seth Young of FSU discovered that low oxygen and sulfide levels in oceans played a larger role in ancient mass extinction than researchers previously thought. The study was the first to use measurements from several sites to examine the conditions that contributed to the second-largest extinction event on Earth.
“We know that life had to survive and persist after this mass extinction, and we now have an indication that at least this location had enough oxygen to support life. That’s consistent with what you find in the rock and fossil records, which are that reefs are persisting through this extinction event,” said Young.
