Rapid changes in marine oxygen levels may have played a significant role in driving Earth’s first mass extinction, according to a new study led by Florida State University researchers. About 443 million years ago, life on Earth was undergoing the Late Ordovician mass extinction, or LOME, which eliminated about 85% of marine species. Scientists have […]
Researchers find low oxygen and sulfide in the oceans played greater role in ancient mass extinction
Florida State University researchers have new insight into the complicated puzzle of environmental conditions that characterized the Late Ordovician Mass Extinction (LOME), which killed about 85% of the species in the ocean. Their work on the 445-million-year-old mass extinction event was published online in the journal AGU Advances on Monday. “We found that reducing conditions […]
