From their earliest diversification in the Cretaceous Period (145 million to 66 million years ago), angiosperms rapidly came to dominate the land flora. Today there are more than 300,000 species of flowering plants, which account for more than 90 percent of the diversity of vascular plants.
Fold mountains
