OBS: The rocks of Britain and Ireland, which date from between 600 and 400 million years ago, owe their origin - according to accepted theory - to the growth, filling and final contraction of an ocean known as the Iapetus.

OBS: The Iapetus Ocean is often referred to as ""Proto-Atlantic Ocean"" and was located between Euromerica and Gondwanaland.
