Sedimentary rocks are widespread. They include the Old Red Sandstones from the Devonian period. These are common in the ‘ridge and valley’ landscape that runs across much of south-west Ireland.

How was Howth Head formed?
The geology is essentially the same as that of Howth Head and Bray Head, but better exposed. The rocks were formed when the Iapetus Ocean (see story panel on page 13) was young and had not long before opened up as an ocean. This was caused by the sea-floor spreading as continents moved apart.
Was Ireland once tropical?
Between 400 million and 300 million years ago, parts of Northwest Europe, including much of Ireland, sank beneath a warm tropical sea.
Why is Ireland so rocky?
At that time, Ireland was part of a shallow sea between two land masses near the equator. Shifting continents raised a part of seabed above the the sea level, which later became Ireland, and over hundreds of millions of years, the mud evolved into a tough, finely-grained limestone just below its surface.

Were any dinosaurs found in Ireland?

Ireland was underwater for significant portions of time during the age of the dinosaurs, so there is less chance of land animals such as dinosaurs being preserved in the rocks that are of a suitable age.
