* Paleontology: This is the study of prehistoric life, including fossils, ancient environments, and the history of life on Earth. Paleontologists would analyze the fossilized remains of the organism to understand its anatomy, behavior, and the environment it lived in.
* Geology: This branch of science deals with the Earth's composition, structure, and processes. Geologists would study the rock layers where the fossil was found, helping to understand the age of the organism and the ancient environment.
* Biology: While not specifically focused on prehistoric life, biology provides the fundamental principles for understanding the organism's anatomy, physiology, and evolution. Studying the fossil's features can help to understand its evolutionary relationships with modern organisms.
* Evolutionary Biology: This field focuses on the history of life and the mechanisms of evolutionary change. Studying the organism's fossils can provide insights into evolutionary processes like natural selection and adaptation.
Therefore, the study of an organism that lived 10 million years ago would involve a collaborative effort between several branches of natural science.
