How did coquina form?

Answer:
Coquina is formed when mineral calcite, phosphate, shells, and shells of living things are squeezed together under pressure as more and more pile upon them as time passes. Later, cementation take place, cementing the particles of mineral calcite, phosphate, shells, and shells of living things together to create an organic rock called coquina.
