The fossilized plant remains are studied in a specific discipline , Paleobotany. This area of knowledge allows us to reconstruct and understand the natural habitats that existed in the most varied territories of the planet. In this way, it is possible to determine which types of plants existed in the different geological eras .
Paleobotany is a specific branch of Paleontology. Thus, Paleontology studies the remains that were preserved in different geological times, whereas Paleobotany focuses on a specific aspect, the fossilized flora.
The botany of the remote past
The knowledge of flora over millions of years is essential to understand the evolution of the landscape over time. The plant remains studied are those that were preserved in sedimentary rocks due to the action of a biochemical process, fossilization. Paleobotany
It is worth noting that in higher territories where there is no sedimentation due to erosion, it is more unlikely to find plant fossils. The type of climate also determines the elimination of plant matter.
As a general criterion, the hardest parts of the plants are preserved.
Anyway, the fossilized remains of plants are classified by belonging to one part or another of the plant (leaves, stem, seeds and fossilized resin).
In addition to the study of plant fossils, paleobotany also analyzes fossil woods and algae, as well as the interaction between animals and plants (plants colonize the terra firme, but at the same time serve as food for different species of animals).
In short, this discipline provides relevant information on other areas, such as geology, climatology and biology. In this sense, specialists in paleobotany establish correlations between the remains of fossilized plants and the various information related to the geological past (when the links are related between a fossilized plant and an animal remains, it is called a biocorrelation). In some countries there are paleobotany museums and they are usually located near botanical gardens. Paleobotany
Other disciplines dedicated to reconstructing the past
There are many areas that focus their research on knowledge of the past. Archeology studies the material remains of ancient civilizations. Genealogy is focused on the descent of individuals and families and through it it is possible to develop a family tree. Chronology facilitates the determination of the temporal order of historical episodes. The writing forms of ancient civilizations are studied in the field of paleography . Paleobotany
All these areas have an independent character , but basically they are auxiliary sciences at the service of history.
