To easily learn about the amount of rainfall at that time and the kinds of plants that grew then, scientists should study fossilized pollen and tree rings.
- Fossilized pollen can provide information on the types of plants that were present in a given area, which in turn indicates the types of vegetation that thrived under past climate conditions, including rainfall.
- Tree rings can indicate environmental conditions such as rainfall patterns and temperatures, as the width of the rings can reflect growth conditions for the trees.
These two specimens together would offer valuable insights into both rainfall amounts and the vegetation present during that time period.
