Back in 1994, Scottish Natural Heritage, together with the BGS, published a guidebook entitled Cairngorms: A landscape fashioned by geology. With the publication of Argyll and the Islands: A landscape fashioned by geology, it has now extended this excellent series to 20 such guides.

The British upper Ordovician has a spectacular variety of invertebrate fossils. The marine communities in which they lived developed on a number of microcontintents and terranes, associated with tectonically active areas of the Earth’s crust.

The Caithness area of Scotland is important for its geology, but is also well known for its palaeontology. The Caithness Flagstones are famous for fossil fish and the Helmsdale Fault for the Helmsdale Boulder Beds deposit, beside an active submarine fault scarp. The area even once had its own ‘gold rush’ and you can still try your luck at panning there today at Kildonan.
