Paleobiology is the study of ancient life forms and their interactions with the environment. It combines aspects of paleontology, which focuses on fossils, and biology, which examines living organisms. Paleobiologists analyze fossilized remains to understand the evolution, behavior, and ecology of extinct species. This field helps scientists reconstruct past ecosystems and climate conditions, providing insights into how life has changed over millions of years. By studying ancient organisms, such as dinosaurs and marine reptiles, paleobiology contributes to our understanding of biodiversity and the processes that drive evolution.
