Trace fossils are geological records that provide evidence of the activities of ancient organisms. Unlike body fossils, which are the remains of the organisms themselves, trace fossils include footprints, burrows, and feeding marks. These fossils help scientists understand how prehistoric creatures moved, lived, and interacted with their environment. By studying trace fossils, researchers can gain insights into the behavior and habits of extinct species. For example, dinosaurs left behind footprints that reveal their size and walking patterns. Additionally, trace fossils can indicate the presence of marine life in ancient oceans, shedding light on the ecosystems of the past.
