A beach.
I think sea arch not sure though
The accumulation of sediment found along the shore of a lake or ocean is called a beach. Beaches are formed by the deposition of sand, gravel, and other sediments carried by waves and currents, often shaped by tides and weather patterns.
Some fossils are found in the sedimentary rocks - along with shells and sediment.

The accumulation of sediment at the bottom of a continental slope is referred to as continental rise. This phenomenon occurs in oceans throughout the world.
Fossils and sediment
It is found in faeces
Gold found in river sediment is referred to as an alluvial deposit.
Rivers carry sediment, which when deposited at the beach, increases the land. Similarly, rivers can carry sediment away from a beach, also changing its shape. These two forces can work together to effectively move sediment from one area of the beach to another. Similarly, storms also move sediment.
Stromatolites
small and large sediment
Amorphous sediment in urine are things like crystal phosphates, uric acid stones or calcium stones that are found in the urine. Certain amorphous sediment found in urine is normal. The cause of amorphous sediment depends on the type of sediment. For instance, uric acid stones can be caused from not drinking enough liquids.
