The coral reefs existing today began growing as early as 50 million years ago. Most established coral reefs are between 5,000 and 10,000 years old. Although size can be a good indicator of the age of a coral reef, it is not a certain indicator.he coral reefs existing today began growing as early as 50 million years ago.

There are complex factors which both add to the growth of a reef and take away from it. For instance, attack by certain organisms and wave destruction will contribute to a decline in reef size. On the other hand, a growing reef can trap sediments as they are moved along by currents, thus adding to its thickness.uch reef growth rates have been reported as high as 414 millimetres per year in the Celebes. 5 At such a rate, the entire thickness of the Eniwetok Atoll could have been formed in less than 3,500 years.
