Final answer:
The climate when the Burlington Limestone was being deposited was likely warm and marine, indicated by the sediment type and the presence of marine organism fossils such as those found in similar carbonate deposits and suggested by the paleoclimate data inferred from fossil content.
Step-by-step explanation:
Understanding the climate when the Burlington Limestone was being deposited requires us to look at various geological and biological clues. Sediments such as limestone can provide valuable information about past climates because they contain fossils and other materials that indicate environmental conditions at the time of their formation.
During the time the Burlington Limestone was forming, indications from the type of sediment and fossils, like Picea, suggest that the climate was likely to have been warm and marine in nature, supporting diverse marine life.
Furthermore, evidence from similar carbonate deposits like the white cliffs of Dover, which are composed of marine organisms' cacareous skeletons, supports the inference of a warm, shallow marine environment for the Burlington Limestone as well.
Fossils serve as an excellent climate proxy, as seen in the example of palm tree fossils from the Green River Formation indicating a subtropical climate in Wyoming during the Eocene. This use of multiple datasets, including the sedimentological context and fossil content, allows scientists to reconstruct the climatic conditions prevailing during the time these sediments were deposited.
