- A: Animal burrow
- B: Dinosaur bone
- C: Shark tooth
- D: Petrified wood
Correct Answer: A: Animal burrow
Explanation:
A trace fossil, also known as an ichnofossil, is evidence of the activity or behavior of ancient organisms rather than their physical remains. Examples of trace fossils include footprints, burrows, nests, coprolites (fossilized dung), and feeding marks.
Why not the other options?
- B: Dinosaur bone – This is a body fossil, representing the preserved physical remains of the organism.
- C: Shark tooth – Like dinosaur bones, this is a body fossil, not a trace of activity.
- D: Petrified wood – This is the fossilized remains of plants, not evidence of an organism’s behavior.
Trace fossils, like animal burrows, offer valuable insights into the habits and environment of ancient creatures, such as how they moved, lived, or interacted with their surroundings.
