Question

Which is an example of a trace fossil?

animal burrow
skin of organism
preserved bone
petrified wood

Answer 1

An example of a trace fossil is an **animal burrow**. Trace fossils are records of biological activity and behavior, such as burrows, tracks, or feces, rather than the physical remains of the organisms themselves. The other options—skin of an organism, preserved bone, and petrified wood—are not trace fossils, as they are direct evidence of the organism's physical structure.
