This stretch of shoreline is one of the continent's best locations for studying rocks and fossils of this age. It represents a continuous, chronological record of a time when there was more life in the seas than there was on land. Arisaig's cliffs and the fossils in them were deposited in an ancient sea more than 200 million years before the evolution of dinosaurs. Read more about Arisaig and the fossils found there. |
