Final answer:
Trace fossils are indirect evidence of past life activities, like footprints and burrows. Examples include footprints, burrows, and feeding marks.
Step-by-step explanation:
Trace fossils are the indirect evidence of past life activities, such as footprints, burrows, or feeding marks. Three examples of trace fossils are:
- Footprints: These are impressions made by the feet of organisms when they walked on a soft sediment. They can provide information about the size, behavior, and posture of the organism.
- Burrows: These are tunnels or holes made by organisms in sediment or rock. They can give insights into the behavior and ecology of the organisms that made them.
- Feeding marks: These are traces left behind by organisms while feeding, such as bite marks or scrape marks. They can help identify the type of organism and its feeding habits.
