erupted lavas and volcanic ash near Dingle, Co. Kerry. Shallow
seas contained corals, brachiopods, and trilobites, and plants
grew on dry land for the first time. The Leinster granite was
injected into the crust.
430 million years ago a large
continent called Gondwana was situated largely in the southern
hemisphere. It was made up of present-day southern Europe, Afrca,
Antarctica, India, Australia and South America. A shallow ocean
called Iapetus separated Gondwana from another continental area
called Laurentia that included Scandinavia and North America.
The area that is now Ireland was a shallow sea that separated
between parts of Laurentia.
