Cretaceous-Terrestrial Revolution

The Cretaceous-Terrestrial Revolution, occurring around 100 million years ago, was a time of significant change in Earth's ecosystems. During this period, many groups of land plants and animals, including flowering plants, insects, and modern mammals, rapidly diversified and spread across continents. This revolution transformed terrestrial environments, leading to more complex ecosystems with new interactions and habitats. It marked a major shift from earlier, simpler ecosystems and set the stage for the diversity of life we see today on land.
