113-Million-Year-Old Fossils Reveal Volcanic CO2 Impact
Fossils show ocean acidification caused plankton extinction. Volcanic CO2 made oceans acidic.

A recent study has uncovered the cause of a major planktic foraminifera extinction that occurred 113 million years ago. The research reveals that massive volcanic eruptions released large amounts of carbon dioxide into the atmosphere, leading to ocean acidification. This chemical shift made it difficult for the planktic foraminifera to form shells, ultimately resulting in their extinction.
The study's findings were based on the analysis of tiny fossils, which provided evidence of the ocean's chemical composition at the time. Researchers used calcium isotopes in the shells of the planktic foraminifera to determine the extent of ocean acidification. The results showed that the increased acidity of the ocean waters hindered the ability of the planktic foraminifera to form shells, which are essential for their survival.
The planktic foraminifera play a vital role in the marine ecosystem, serving as a food source for many other organisms. Their extinction would have had a significant impact on the entire ecosystem. The study's findings offer insights into the potential impacts of modern ocean acidification, which is also caused by increased levels of carbon dioxide in the atmosphere.
Ocean acidification is a major concern for marine ecosystems, as it can have far-reaching consequences for many species. The study's results highlight the importance of monitoring and mitigating the effects of ocean acidification. By understanding the causes and consequences of past extinctions, researchers can better predict and prepare for the potential impacts of future environmental changes.
The research team's use of calcium isotopes in shells to study ocean acidification is a significant breakthrough. This method provides a new tool for scientists to study the chemical composition of the ocean in the past and present. The findings of this study contribute to our understanding of the complex relationships between the ocean, atmosphere, and marine ecosystems.
In conclusion, the study of 113-million-year-old fossils has revealed the cause of a major planktic foraminifera extinction. The findings highlight the importance of understanding the impacts of ocean acidification and the need for continued research into this critical issue. As the world continues to grapple with the challenges of climate change, studies like this one provide valuable insights into the potential consequences of environmental changes.
The implications of this study are far-reaching, and the findings have significant relevance to modern-day concerns about ocean acidification.
