Present-day tidal flats are commonly colonized by microbial mats, which alter sediment properties as a consequence of the interaction between microorganisms and sediments. Thus, their recognition in ancient siliciclastic tidal deposits is important to understand their impact on sediment dynamics and their role on the formation and preservation of sedimentary structures, such as vertebrate footprints.
