Coral fossils
Following on from Kerrnowclimber's description of the fossils that we found on Ben Bulben I have attached a photograph of one of the common species (Caninophyllum) that can be found in the Dartry Limestone (which forms the cap to the Ben Bulben plateau). The Dartry Limestone was deposited in shallow equatorial seas above a shelf of rock. Coral reefs fringed the shelf much like the present-day barrier reefs and coral atols. There were a wide variety of corals living on the reef. Some coral species evolved little over millions of years whilst other species were short lived. Geologists can identify the different species from their fossils and this helps to date the rocks and to correlate rocks across different exposures (eg between Ben Bulben and the Burren). The idenitification of the species requires careful measurement and observation of features in the coral fossil such a sub-divisions, central core and septa (which are the radial 'spokes' of the creature).
