Scenarios about 'cretaceous'
The Cretaceous period was the final era of the dinosaurs' reign, spanning from approximately 145 to 66 million years ago before ending with a catastrophic mass extinction event. This geological time period saw the evolution of flowering plants, the breakup of supercontinents, and the development of shallow inland seas, creating diverse ecosystems that differed significantly from our modern world. In alternate history scenarios, the Cretaceous often serves as a point of divergence for timelines exploring how Earth might have developed if the extinction event had been altered or delayed.
