Woody plants have many different kinds of leaves. Some leaves have very smooth edges, while other leaves have jagged edges, as shown in the diagram. The characteristics of plant leaves vary with the climate in which the plant naturally grows. Some scientists discovered an area with many fossilized leaves of woody plants. The scientists used data from samples of 100 leaf fossils to compare the number with smooth-edged leaves and the number with jagged-edged leaves.
The scientists concluded that the plants had grown in a hot climate.
