Paleobotany is the study of ancient plants that have been preserved by carbonization, waterlogging, or freezing. Some plants have been preserved almost intact in frozen soils and in amber. Pollen is also very resistant and has characteristic patterns for identification. The earliest land plants grew in the Cambrian period, but some water plants flourished earlier. Such plants provide important evidence of ecosystems.
