Paleobotany is the study of ancient plants through the examination of fossilized remains. This branch of paleontology helps scientists understand the evolution of plant life, ancient ecosystems, and how climate changes have affected vegetation over millions of years. By analyzing plant fossils, researchers can reconstruct past environments and gain insights into the Earth's history. Paleobotanists often work with various types of fossils, including leaves, seeds, and wood. They may also study coal deposits and pollen grains to gather information about past flora. This research contributes to our knowledge of biodiversity and the relationships between ancient and modern plants.
