Abstract

The article discusses new research indicating that ammonites, a group of coil-shelled mollusks, survived the mass extinction event caused by an asteroid impact 66 million years ago, contrary to previous beliefs that they perished immediately. A study published in Scientific Reports reveals that some ammonite species lived for at least 68,000 years after the impact, as evidenced by fossil findings in Denmark. Researchers utilized advanced techniques to analyze sediment layers surrounding the fossils, confirming their post-impact existence. Despite their survival, the study suggests that environmental changes ultimately led to their extinction, highlighting the complex nature of mass extinctions. [Extracted from the article]
