Such scientists are called paleogeographers. Paleontology aids in the location of oil. Oil is often found in rocks that contain certain fossils. Oil companies use such fossils as a clue to where to find oil. Vertebrate paleontology is concerned with extinct fishes, amphibians, reptiles, birds, and mammals.
Paleobotany is the study of fossil plants.
