A fossilized trackway impression is commonly referred to as an ichnofossil or trace fossil. Ichnofossils are the preserved traces or impressions left behind by ancient organisms, including footprints, trackways, burrows, nests, and other signs of their activity. In the case of a trackway impression, it specifically refers to the preserved marks left by the movement of an organism, such as footprints or a series of footprints in sediment or rock. These trackway impressions provide valuable information about the locomotion, behavior, and interactions of ancient organisms, as well as the paleoenvironmental conditions in which they existed. Ichnofossils can be found in various types of sedimentary rocks, including those associated with ancient terrestrial, freshwater, or marine environments.
