When was the permian extinction
So, "if oxygen is 12%, sea level would be like living at 5.3 kilometers," says Huey. With oxygen at the mid-Permian's peak of 30%, animals probably could have breathed easily at any altitude on Earth, says Huey. But as oxygen levels dropped, animals capable of living at 6.0 kilometers in the mid-Permian would have been driven down to 300 meters.Likewise, the reptiles that survived the late Permian extinction some 250m years ago, which killed off 90% of marine and 70% of terrestrial species did not clearly foreshadow the pterosaurs and ...
