What evidence do paleobotanists look for that indicates the movement of plants from water to land?

Each leaf contains a waxy cuticle, this waxy cuticle is like an epidermal cell that covers the upper and lower surface of a leaf.  The cuticle repels water, prevents rapid desiccation, acts as a selective filter in reflecting harmful ultraviolet light, and allows the absorption of visible light for photosynthesis. The Waxy cuticle decrease evaporation from leaves.
