New Theory for What Caused Earth’s Second-Largest Mass Extinction. Diatoms like this one can be deformed if exposed to high levels of metals in the ocean. New research suggests that lead and other metals caused deformities in prehistoric marine creatures that led to one of the Earth’s biggest mass extinctions.

What was the most likely cause for the end Ordovician mass extinction?

Around 443 million years ago, 85% of all species on Earth went extinct in the Ordovician-Silurian extinction. The extinction was a most likely a result of global cooling and reduced sea levels, which dramatically impacted the many marine species living in warm, shallow coastal waters.
