Belemnite Paleoclimatic Reconstructions

Belemnite Paleoclimatic Reconstructions

Belemnites are extinct cephalopods that lived during the Mesozoic era. Their fossils are valuable tools for paleoclimatic reconstructions, as they were widespread and abundant in ancient oceans. By studying the isotopic composition of their shells, scientists can gather information about past climates, such as temperature and ocean chemistry.

Isotopes of oxygen and carbon preserved in belemnite shells provide insights into past environmental conditions. Oxygen isotopes can reveal information about seawater temperature, while carbon isotopes can indicate changes in the carbon cycle. By analyzing these isotopes, researchers can reconstruct ancient climates and understand how they have changed over millions of years.
