Paleontology is filled with mysteries about organisms such as plants and animals that lived thousands, millions, and billions of years before the first modern humans walked the earth. To solve these mysteries, paleontologists rely on the excavation, analysis, and interpretation of fossils. Fossils are the remains or traces of ancient life forms that are usually preserved in stones and rocks. Examples include bones, teeth, shells, leaf imprints, nests, and footprints. Such fossil discoveries reveal what life on our planet was like long ago. Fossils also disclose the evolution of organisms over time and how they are related to one another. While fossils reveal what ancient living things looked like, they keep us guessing about their color, sounds, and most of all their behavior. Each year, paleontologists continue to piece together the stories of the past.
