Paleontology focuses on the history of life on planet Earth millions of years ago. This research is based on evidence provided by fossils. Fossils are the remains of animals, plants, and other organisms preserved in layers of rock. Paleontology overlaps with many other types of science, which all try to describe what life on Earth was like millions of years ago. Dinosaurs are an example of an extinct animal that scientists have learned about through studies of fossils found around the world. Many different types of bones of dinosaurs have been dug up and reassembled in various museums. Although fossil study is one of the more commonly known types of paleontology, there are other branches of it that promote the study of early life on Earth. These other branches include studying aspects of the climate and environment. Biology, geology, and botany are a few of the fields that support paleontology.
