How does coquina form?

Answer:

Coquina forms when shells, mineral calcite, and sometimes phosphate settle on the bottom of the ocean, while more and more pile upon them as time passes. Soon, as more pressure builds up, all the shells, mineral calcite, and phosphate press together to create a hard structure in the form of a rock called coquina.
