What is the main composition of most fossils?
What is the main composition of most fossils?
- Mineralized remains of plants and animals
- Soft tissues of organisms preserved in ice
- Petrified remains of ancient trees

What is the role of vultures and other scavengers in the fossilization process?
What is the role of vultures and other scavengers in the fossilization process?
- They assist in the preservation of soft tissues in fossils
- They pick away the muscles and organs of a dead organism, leaving behind the bones (correct)
- They help in the calcification of the hard-parts of organisms

Study Notes
Fossilization and Extinction
- Extinction: The process by which a species or group of species dies out and no longer exists.
Composition of Fossils
- Most fossils are composed of mineralized remains, which are the original organic materials replaced by minerals from the surrounding environment.
Role of Scavengers in Fossilization
- Vultures and other scavengers play a crucial role in the fossilization process by dispersing and destroying organic remains, preventing the formation of fossils.
Fossilization Process
- When a hominid's bones and footprints are covered by rising water levels, they are protected from scavengers and oxygen, allowing for the potential formation of fossils.
- The correct order of events in the fossilization process is: death, burial, replacement of organic materials with minerals, and compaction of the fossilized remains.
