Coquina comes from the Spanish word for little shells. It was first recorded as a description of the rock that explorers found on the coast of Florida centuries ago. These shells come from the base of the Uinta Mountains in Utah, which was an ancient shoreline during the Cretaceous Period when the dinosaurs were holding court. Imagine your mac n cheese solidified into one, big mass and you have an idea of how these shells appear in this rock. Lab: Shark Tooth Jambalaya, macaroni Coquina. Fossil Profile: Coquina.
