Corals live in marine water, at most depths and latitudes. Tabulae (singular, tabula; from the Latin for board or tablet) are horizontal plates that span across individual corallites (the spaces occupied by a single, living polyp). They may have first evolved during the Precambrian and are still found living today. They have a very porous or spongy skeleton made of aragonite that is strengthened by radiating septa (the main ones being arranged in groups of six), dissepiments and sometimes a columella. Among the most common tabulate corals in the fossil record are Aulopora, Favosites, Halysites, Heliolites, Pleurodictyum, Sarcinula and Syringopora. Corrections?

These colonial corals grew in mounds, branching shapes, as chain-like shapes, and even in shapes resembling pipe organs. Rugose corals are solitary or colonial types with bilateral symmetry. I recently/presently went on a Tabulate coral collecting trip to Percy Priest Lake TN and found what I believe is a Roguse coral (horn coral) inside a chunk of Tabulate coral. The colonies were made up of tubes called corallites and in each tube lived a tiny sea anenome like creature called a polyp that fed on plankton. encrusting upon Favositessp.

In a recent study, Zapalski (2014) studied isotopes of oxygen and carbon derived from the skeletons of Silurian to Permian tabulate corals (including species of Favosites, Syringopora, and Aulopora; see examples below) and found that some specimens had isotopic values consistent with those of modern hexacorals that harbor zooxanthellae. This is because the Earth's rotation has slowed down so that there are 3540 fewer days in the year now compared to Devonian times. Model by Emily Hauf. However, a mass extinction event took place at the end of the Permian, when over 90 per cent of all invertebrates became extinct, including all tabulate and rugose corals. from the Devonian Onondaga Limestone of Williamsville, New York (PRI 76821).
