It takes a long time for the tiny coral polyps to create an entire reef. Coral formations grow an average of 1 to 8 inches per year. While ancestors of today's coral date back 240 million years, today's reefs began growing more than 50 million years ago, although most reefs are about 5,000 to 10,000 years old.hile ancestors of today's coral date back 240 million years, today's reefs began growing more than 50 million years ago, although most reefs are about 5,000 to 10,000 years old.
