Ancient #ocean oxygenation timeline revealed
https://phys.org/news/2024-04-ancient-ocean-oxygenation-timeline-revealed.htmlLate Paleozoic #oxygenation of marine environments supported by #dolomite U-Pb dating https://www.nature.com/articles/s41467-024-46660-7
"Their record indicates a dramatic increase in the oxygenation of the #oceans during the Late #Paleozoic era, hundreds of millions of years after the emergence of the first #animals. This aligns with other evidence... supports the hypothesis that animals have evolved in oceans that were mostly oxygen-limited"

"#Cloudina originated in a low #oxygen environment with periods of notably higher #oxygenation... it was not a case of sustained oxygenation that resulted in the appearance of #skeletonization... high #carbonate concentrations in the ocean were necessary"
