Redefining Pristine
Modern marine oxygen-deficiency research inspires search for fossil record
Mayo 11, 2018
Smithsonian scientists who documented massive mortality of corals and reef organisms meticulously studied one of the apparent causes: oxygen deficiency. A Smithsonian paleobiologist asks if the recent fossil record shows signs of similar hypoxia events.
