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. 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 … ….

Although indigenous peoples have used coral reef resources for tens of thousands of years (Kirch, 2017) and coral fossils were known in Nicolaus Steno's time (the late 17th century; Rosenberg, 2009), coral reefs were first brought to wider European knowledge by accident, at 11 p.m. on 11 June 1770, when Lieutenant James Cook's ship, HM Bark Endeavour, “bumped” and ran ...

Coral reefs provide significant evidence for former sea-level positions because of their geological preservation and suitability for dating. Interpretation of this evidence presumes an understanding of reef geomorphology, modern reef organism distributions, and environmental factors influencing them.

In chain corals, the splitting ...
