Paleobotany is the study of ancient plant life through fossils, plant remains, and other evidence found in geological formations. This field of research helps scientists understand the evolution of plants, their interactions with the environment, and how they have evolved over time. Paleobotanists use a variety of techniques, such as molecular analysis, isotope analysis, and microscopy, to study plant fossils and reconstruct past ecosystems. This information can provide valuable insights into past climates, vegetation patterns, and the history of plant biodiversity on Earth.
