Mud cracks are formed when wet sediment dries and shrinks, causing cracks to form. This is more commonly found in shales, which are composed of fine-grained sediment that can retain water and easily dry out, as opposed to sandstones, which are coarser-grained and typically do not retain as much water. Bedding, cross stratification, and ripple marks are all sedimentary features that can be found in both shales and sandstones.
