* Paleontology: This is the primary branch of science focused on the study of prehistoric life, including fossils. Paleontologists would analyze the organism's fossilized remains to determine its species, anatomy, behavior, and environment.
* Geology: Geologists would help to determine the age of the fossils and the environment in which the organism lived. They study the layers of rock and sediment where the fossils are found.
* Biology: Biologists would analyze the organism's anatomy and evolutionary relationships to other species. They would use the fossil record to understand the organism's place in the tree of life.
* Evolutionary Biology: This field focuses on the study of how organisms change over time. Evolutionary biologists would use the fossil record to study the evolution of the organism and its ancestors.
* Zoology/Botany: Depending on whether the organism was an animal or a plant, zoologists or botanists respectively would specialize in the study of the organism's anatomy, physiology, and behavior.
These branches of science often work together to understand prehistoric life. For example, a paleontologist might discover a new fossil, a geologist might determine the age of the fossil, and a biologist might study the organism's anatomy and evolutionary relationships.
