Fossil Horn Coral

These old OLD stock fossil horn corals from Morocco have a stunning contrast between nicely silicified black chambers and some orange mineralization. Their structure is also very neat! Fun fact: tithes species of coral would grow straight up but generally got too heavy to support their own weight and would fall over and begin growing vertical again after falling. Hence why some have wild 90 degree bends in them. These coral fossils are esthetically pleasing and so cool!
