A fossil is the remains of a plant or an animal that lived long ago. Fossils occur when an organism dies and the remains are covered with water and sediment layers. In addition to this process, it may also be the case that fossils were created in that resin is dripped over millions of years ago over the plant or animal. These processes take millions of years after the fossilized remains of the organism. We call this a fossil.
