Paleobotany is the study of ancient plants and their evolution through time. By examining fossilized remains, scientists can learn about the types of vegetation that existed millions of years ago, how they adapted to their environments, and how they interacted with other organisms. This field helps us understand the history of our planet's climate and ecosystems. Researchers in paleobotany often work with fossils of plants like ferns, conifers, and flowering plants. These fossils provide clues about past climates and can reveal how plants responded to changes in their surroundings. Ultimately, paleobotany contributes to our knowledge of biodiversity and the Earth's ecological history.
