How might scientists be able to use fossils to infet that the climate of the central united states was a lush subtropical forest millions of years ago?

Answer 1

Scientists can analyze the types of fossils found in sedimentary rock layers, such as plant remains, pollen, and animal bones, to infer past climate conditions. The presence of tropical plant species, such as ferns and cycads, along with fossils of warm-adapted animals, suggests a lush subtropical forest environment. Additionally, isotopic analysis of these fossils can provide insights into historical temperatures and precipitation patterns, further supporting the inference of a warm, humid climate. By comparing these findings with modern ecosystems, scientists can reconstruct the ancient climate of the central United States.
