As organisms live, grow, and move in their environments, they leave all sorts of traces in their surroundings, and these can become fossilized just like body parts can. Trace fossils (ichnofossils) can include evidence of burrowing, walking, feeding, and more. Individual trace fossils are great for understanding the behaviors of ancient organisms, and communities of trace fossils can help us track major changes in ecosystems through time.
In the news: damaged cave bear, shrinking dinosaurs, koala lemurs, and megaripples.
