WebHow Fossils Form A fossil is any remains or trace of an ancient organism. Fossils include body fossils, left behind when the soft parts have decayed away, as well as trace fossils, such as burrows, tracks, or fossilized waste (feces) (Figure 11.4). Figure 11.4: Coprolite (fossilized waste or feces) from a meat-eating dinosaur. WebThere are four main steps to making a fossil (see image below): First, an organism dies. Anaerobic conditions exclude bacteria and other predators that consume bodies before burial, so organisms that die in the deepest ocean or in a deep lake are more likely to become fossils. Next, the remains need to be buried in soft sediment.
