Dinosaur-killing impact crater might have been teeming with life

A new study suggests that the impact crater that led to the extinction of the dinosaurs may have been teeming with life, thanks to hot, nutrient-rich water that lasted for over 5 million years after the impact. Researchers found that the crater, located in what is now the Yucatan Peninsula in Mexico, was a shallow lake with a sedimentary basin that could have supported a diverse ecosystem. This ecosystem may have consisted of bacteria, archaea, and other microorganisms that thrived in the crater's warm and nutrient-rich environment. The study's findings offer a new perspective on the idea that life on Earth may have been more resilient after the mass extinction event than previously thought.
