Article Synopsis
- The Late Cretaceous period saw a shift from a very warm climate to cooler temperatures without major ice formation on land.
- Researchers utilized a method called TEX86 to analyze sea surface temperatures (SST) from the North Atlantic region during the Campanian-Maastrichtian interval (around 83-66 million years ago).
- Their findings indicate that North Atlantic SSTs were initially around 35°C but dropped significantly to below 28°C by the Maastrichtian, suggesting a widespread cooling effect likely linked to decreasing atmospheric carbon dioxide levels.
The Cretaceous-Paleogene boundary approximately 65.5 million years ago marks one of the three largest mass extinctions in the past 500 million years. The extinction event coincided with a large asteroid impact at Chicxulub, Mexico, and occurred within the time of Deccan flood basalt volcanism in India.
