In our web store we sell fossil corals including polished fossil corals and raw / natural fossil corals. Coral is a collective name for often small marine animals. They are animals of only a few millimeters that, with their tentacle wreath, look a bit like a sea anemone. These animals, also called polyps, often live in colonies. Corals originated the cambrium about 542 million years ago. But they only became really widespread in the Ordovician some 442 million years ago. Here we sell both polished fossil corals and raw / natural fossil corals. Raw / natural fossil corals are fossil corals that we sell as found. Fossil polished fossil corals are fossil corals that have been processed. In these fossil corals, the structures of the corals are often very beautiful.
