To learn about the amount of rainfall at that time and the kinds of plants that grew, scientists should study fossilized pollen and tree rings.
- Fossilized pollen can provide information about the types of plants that existed in the area during that time period, as different plants produce distinct pollen types.
- Tree rings can indicate both growth conditions and environmental factors, including rainfall levels. The width and density of tree rings can reveal patterns of wet and dry years.
Together, these two specimens offer valuable insights into historical rainfall and vegetation.
