Douglas S. Robertson, William M. Lewis, Peter M. Sheehan and Owen B. Toon K-Pg extinction patterns in marine and freshwater environments: The impact winter model Journal of Geophysical Research: Biogeosciences 118

Version of Record online: 11 JUL 2013 | DOI: 10.1002/jgrg.20086

Key Points

  • Marine K-Pg extinction was due to loss of photosynthesis in an impact winter
  • It was separated in time from the terrestrial extinctions by months to years
  • Lack of extinction in freshwater is due to the resilience of those ecosystems
