2. **Types of Fossils**:
- **Whole Bodies and Skeletons**: These are the complete remains of prehistoric organisms. Whole body fossils are rare but provide a detailed look at the organism's structure.
- **Coprolites**: These are fossilized feces of ancient animals. They can provide information about the diet and behavior of the organisms that produced them.
- **Impressions**: These are the marks left by organisms, such as footprints or leaf imprints, preserved in sediment.
- **Casts and Moulds**: A mould is a hollow impression of an organism, while a cast is formed when minerals fill the mould, creating a replica of the original organism.
