Each of these specimens have been prepared under microscope using micro-pneumatic tools and micro air abrasives. This tedious process is used to reveal all of the surface detail. During the digging, cutting and preparation process some of the horn corals may have popped off. Those that did were remounted to their original locations.
Neozaphrentis is a rugose coral. It is a type of solitary rugosan coral that is often referred to as horn corals because of a unique horn-shaped chamber with a wrinkled, or rugose, wall.
All horn corals live in a cup called a calyx (KAY-licks). The calyx often has radially aligned ridges or grooves, which are called septa. These septa were the skeletal support plates for the coral animal or polyp. When alive, the horn-shaped skeleton of the coral animal was attached to the sea floor with the pointy end down. The living coral polyp lived on the top of the skeleton with its arms or tentacles pointing upward.
