What does the Great Barrier Reef tell us about both Evolution and the Age of things?

have you looked into the various coral dating methods and the annual growth data? there are some interesting things happening and many of the older samples are from ... the great barrier reef see this article about surface temperature information from corals (click)and this article about coral and GEOCHRONOMETRY (click)and this series of "slides" about coral cores (click)I can see an annual coral chronology being built similar to the one for tree-rings and providing lots of information about sea conditions then linked to ages.
