Short summary
This study analyzed ancient climate patterns using plant fossils called palynomorphs. We identified 69 different palynomorphs from different plant groups (e.g., ferns, gymnosperms, angiosperms) and used statistical methods to support our findings. We found a trend towards increased humidity, likely influenced by a weather phenomenon called the Intertropical Convergence Zone.
