Trace Fossils
These trace fossils represent the work of insects on a living tree over 200 million years ago! NPS/MARGE POST Some fossils are not actual remains of an organism, such as bones, teeth, leaves, and seeds. A trace fossil is a fossilized track, trail, burrow, boring, or other structure that records the presence or behavior of the organism that made it rather than a piece of the organism itself.
