Paleontology
Paleontology is the study of prehistoric life through fossil records and other evidence from deep time to reconstruct ancient ecosystems and evolutionary history. Key areas include vertebrate paleontology (focusing on fish, amphibians, reptiles, birds, and mammals) and invertebrate paleontology (studying organisms without backbones like mollusks, arthropods, and echinoderms).
