They were named after horizontal internal partitions, called tabulae, which developed within each cell (Fossil ...Fossils are the preserved remains of deceased animals in rock.

Coral Fossils. Corals are part of a group of animals called Cnidaria (nid-AIR-ee-a), also called Coelenterata (sel-EN-ter-AH-ta), which includes sea anemones, corals, jellyfish, and hydras. All of these animals are soft bodied and have multiple arms or tentacles, with which they grab food from the surrounding sea water.Coral reefs originated during the Cambrian period, roughly 535 million years ago, although it’s difficult to find fossils from this time. However, during the Ordovician period, which was approximately 100 million years later, there was an abundance of fossils from widespread Heliolitida, rugose, and tabulate corals.The proper name for fossil coral is "agatized coral" or "agatized fossil coral." Agate, with its silicon dioxide composition (SiO 2), is a variety of naturally occurring chalcedony--or microcrystalline quartz--rather than a type of coral. For this reason, fossil coral should not be mistaken for endangered or protected reef coral or precious coral.

Palaeozoic corals. Many Cambrian fossils have at times been called 'corals'. The most coral-like of these are small, cup-shaped, mostly solitary organisms with septa.
