Generalists, with a wide ecological range, appear to have had a better chance of survival …Taxonomy. The classification of corals has been discussed for millennia, owing to having similarities to both plants and animals.

The growth rate varies with age, food supply, water temperature, and species. Atolls and coral reefs are composed of stony coral. Such formations grow at an average rate of about 0.5 to 2.8 cm per year. Common types of stony coral include brain coral, mushroom coral, star coral, and staghorn coral, all named because of their appearance.Many Cambrian fossils have at times been called 'corals'. The most coral-like of these are small, cup-shaped, mostly solitary organisms with septa. Some have an operculum over the calice opening. In total, seven orders of Palaeozoic corals may be recognised, of which the Tabulata and Rugosa are by far the most important. Petoskey stones are a fossil rock made from the coral Hexagonaria percarinata. It is thought that these corals lived during a time before the dinosaurs, when the Lake Huron area was covered by sea. The stone itself is covered in six-sided coralites that are enhanced when wet or polished. When dry, however, the stone resembles limestone.Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.

Definition. A fossil is the mineralized partial or complete form of an organism, or of an organism’s activity, that has been preserved as a cast, impression or mold. A fossil gives tangible, physical evidence of ancient life and has provided the basis of the theory of evolution in the absence of preserved soft tissues.

Other species live in Central and South America, India, Thailand and China.unknown as fossils. The name CORAL is given to a group of cnidarians with calcareous skeletons that live on the sea floor, commonly attached to a hard surface.
