    The first 2 photos were taken on a super bright full sun day against a black background
    Photos 3 & 4 were taken on an overcast day and more accurately show the true beautiful red color
    About 300 million years ago, in the Pennsylvanian age, the coral grew in the oceans in a long cone shape. The outside of the corals had a wrinkled appearance. Rugose means wrinkled.  Thus this now extinct order of corals is called Rugosa.  The fossil is the skeleton of the coral animal or polyp that built the structure from calcium carbonate found in the ocean water.  It lived at the top of the cone and as it got bigger it added more material, each layer a little bigger than the one before creating the cone shape.
    As the corals fossilized the organic material was replaced by silica and other minerals producing the beautiful patterns and colorations.  Colors range from light greys to pinks and sometimes deep reds.
