Sedimentary rock

Available in Lots of Colors and Patterns, Is one of the oldest rock

Present

Coquina is a sedimentary rock which is formed when billions of small clam-like seashell, called Coquina, or cockleshell are die and hence are deposited, buried and turns into a rock when pressure is applied.
