Answer:
Paleobotany, also known as Palaeobotany, is the study of the fossil remains of plants, and flora in general, who make part of botanical studies of ancient times. This study allows paleobotanists to understand the type of plants, and characteristics of environments during ancient times, and throughout history, and understand evolutionary patterns.
Among the other important aspects of paleobotany is that understanding the patterns of how plants used to inhabit certain regions and environments, their distribution and characteristics, as well as their evolutionary patterns, also allows researchers to understand how animals, and other living organisms, existed, lived, evolved and distributed themselves, depending on the environment they were in, and the plants they consumed, if any.
In these remains and fossils of plants found at paleontological sites, scientists are able to find what happened at a certain point, what types of organisms lived in certain regions, how they survived and died out, and how things evolved depending on the changes viewed in the plants.
