Mudcracks
Mudcracks are sedimentary structures that form in muddy sediment as it dries and contracts. They are most commonly found in mudstones, but can also be seen in other sedimentary rocks such as sandstones and shales. The cracks form when the mud is exposed to drying conditions, such as those found during droughts or seasonal changes. …Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition . Sediments and sedimentary rocks are characterized by bedding, which occurs when layers of sediment, with different particle sizes are deposited on top of each other.

Crack formation also occurs in clay-bearing soils as a result of a reduction in water content. Fresh mudcracks.Mudcracks form when a shallow body of water (e.g., a tidal flat or pond or even a puddle), into which muddy sediments have been deposited, dries up and cracks. This happens because the clay in the upper mud layer tends to shrink on drying, and so it cracks because it occupies less space when it is dry.
