Paleobotany is the scientific study of fossil plants. It is a subdiscipline of paleontology and botany. Paleobotanists analyze fossilized plant material, including pollen, spores, wood, leaves, and seeds, to reconstruct the past vegetation of Earth and understand the evolution of plants. These fossils can be found in sedimentary rocks, coal beds, and amber. By studying these ancient remains, scientists can gain insights into past climates, environments, and ecosystems.

The history of paleobotany dates back to the 18th century, with early work by figures like Antoine Laurent de Jussieu and Adolphe Brongniart, who recognized the importance of fossil plants for understanding plant evolution and geological history. Discoveries of fossil plants have been crucial in understanding major evolutionary transitions, such as the colonization of land by plants and the development of forests. Paleobotanical research also contributes to understanding the origin of fossil fuels like coal and oil, which are derived from ancient plant matter.

Paleobotanical evidence is used in various fields. It helps to date rock formations, providing a geological timeline. It also informs our understanding of past biodiversity and extinction events. Furthermore, studying ancient plant adaptations can offer insights into how modern plants might cope with environmental changes. The techniques employed in paleobotany include microscopy, chemical analysis, and comparison with modern plant relatives.
