"Pre-Asteroid Morocco: Unveiling the Diverse Marine Life of 66 Million Years Ago"

Fossils found in Morocco from the latest Cretaceous period reveal a diverse marine ecosystem just before the asteroid impact that caused the mass extinction event 66 million years ago. The discovery of numerous mosasaur species, dominant predators of the time, suggests that marine ecosystems remained diverse until a sudden collapse triggered by the asteroid impact. The findings support the theory that the end-Cretaceous extinction was driven by a catastrophic event rather than a gradual decline, highlighting the resilience and adaptability of life in the face of major disruptions.
