Today it is used as an excellent building material. Once deposited the silt becomes compacted and cemented together into solid stone. Because of it's small grains, it takes millions of years for it to fully form. resulting in significant surface flow. Siltstone is made from silt of course. These ichnofossils generally are composed of sandstone or siltstone, and are found in Pennsylvanian strata, often devoid of other fossils. Silt-sized Siltstones differ significantly from sandstones due to their smaller pores and a higher propensity for containing a significant clay fraction.
