What was vegetation like in the Cretaceous?

During the Cretaceous period, which lasted from about 145 to 66 million years ago, vegetation was diverse and abundant, characterized by the dominance of flowering plants (angiOSperms) alongside ferns, cycads, and conifers. The warm climate and high carbon dioxide levels supported lush forests and widespread plant life, contributing to rich ecosystems. This period also saw the evolution of various plant forms, including the emergence of modern trees and shrubs. Overall, the Cretaceous landscape was vibrant and varied, supporting a wide range of herbivorous dinosaurs and other wildlife.
