Although amber has never been cited as a medium for trace fossils, the present study shows that fossilized resin does contain ichnofossils. Examples of impressions, secretions, protective coverings, domiciles, excretory products and feeding behavior occur in amber. These ichnofossils can be used to determine not only the presence of invertebrates and vertebrates at particular periods in the past, but also aspects of their behavior. Such fossils play a role in understanding past terrestrial ecosystems.
