Answers

The parts of living organisms that are most likely to become fossils are those that are hard and durable, as they are better able to withstand the processes of decay and environmental changes over time. The key components include:
1. **Bones**: The skeletal remains of vertebrates, such as mammals, reptiles, and birds, are among the most common fossils due to their mineralized structure.
2. **Shells**: The hard exoskeletons or shells of invertebrates, like mollusks (e.g., clams and snails) and crustaceans (e.g., crabs and lobsters), are also commonly preserved as fossils.
3. **Teeth**: Teeth, which are made of hard enamel and dentin, have a high potential for fossilization and are often well-preserved in the fossil record.
4. **Wood and Plant Material**: Certain types of wood and plant material, especially those that are dense and lignified, can fossilize into forms such as petrified wood. Seeds and pollen can also be preserved.
5. **Tracks and Burrows**: While not parts of organisms, trace fossils, which include tracks, burrows, and other signs of activity, can provide important information about the behavior and movement of organisms and can be preserved in sediment.
Conversely, soft tissues, skin, and organs are less likely to become fossils, although exceptional conditions (like being quickly buried in an anoxic environment) can sometimes preserve these materials in rare cases.
