If the layer is of dead plants, it is a compressed layer known as a coal seam.
Limestone is made of the shells of dead ocean organisms. Their shells are made of calcite.Hope i helped1 :)
Sedimentary rocks are made out of sediments.
Sedimentary rocks are formed by the lithification (cementing, compacting, and hardening) of existing rock or the bones, shells, and pieces of formerly living things. Rocks are weathered and eroded into tiny particles which are then transported and deposited along with other pieces of rock called sediments. Sediments are cemented together and compacted and hardened over time by the weight and pressure of up to thousands of feet of additional sediments above them. Eventually, the sediments are lithified and become solid sedimentary rock. These sediments that come together are known as clastic sediments. Sediments usually sort themselves by the size of the particles during the deposition process so sedimentary rocks tend to contain similarly sized sedimentary particles. An alternative to clastic sediments are chemical sediments which are minerals in solution that harden. The most common chemical sedimentary rock is limestone, which is a biochemical product of calcium carbonate created by the parts of dead creatures. Approximately three-quarters of the earth's bedrock on the continents is sedimentary.
From the shells and skeletons of dead sea creatures.

Sedimentary rock is formed using dead sea animals' shells and are formed by thousands-millions of years of crushing together under the sea bed. Igneous rock means "born from fire" and is made in volcanoes.

The dead sea is not called the dead sea because people sink in it and die, it's called that because there is no water flow, and no creatures swim in it. That is why it is called the dead sea. It doesn't seem to exist, it's like it is dead.
Calcite is a common constituent of sedimentary rocks, limestone in particular, much of which is formed from the shells of dead marine organisms. Approximately 10% of sedimentary rock is limestone.
Corals are not plants. They are the colonies of dead creatures called polyps. Their skeletons stack to make coral reefs.

Not 'mud', it is the remains of shells and skeletons of dead sea creatures, as well as precipitated calcite that eventually lithify to form limestone.
