Kimmeridge Bay - Isle of Purbeck, Dorset, UK - Rock-Hounding on Waymarking.com

'Kimmeridge is located on the south coast of England, along the southwestern stretch of the Isle of Purbeck and is an excellent location to explore for fossils. The coastline is characterised by tall steep cliffs that run east and west of the beach access. The rock is of the Upper Jurassic period, from around 150 million years ago, a time when the ocean covered this part of the world.

The cliffs at Kimmeridge are subject to rapid erosion, providing ideal conditions for finding fossils. The erosion occurs for different reasons throughout the year. During the winter heavy rain saturates the cliffs, resulting in frequent land slips. Frost shattering may also occur during periods of prolonged cold weather. During periods of hot weather the cliff faces begin to dry, during these times visitors may observe a flurry of small debris falling from the cliffs. The sea also contributes to the erosion, particularly during stormy weather when large waves batter the coastline.

From the beach access point, just south of the village of Kimmeridge, you can head either east or west. Fossils can be found in either direction, but the preferred coastal stretch for most fossil collectors is east.

Additional safety notice

Visitors to Kimmeridge should observe strict safety precautions when exploring the beach or cliffs. In the first instance hard hats should be worn to prevent head injury from potential rock falls. Even small debris when falling from high heights can result is serious injury. Secondly the use of hammers or any other hardware is prohibited by the land owners. Visitors should also keep an eye on the incoming tide which on some occasions may isolate parts of the beach.

Kimmeridge is also close to the neighbouring army firing ranges and as such fragments of military warfare can sometimes be found within the shingle (see below). Local signs warn visitors of the dangers - don't touch, they can be dangerous!

Where to look for fossils?

Fossils are found in abundance right along the coast (heading East) from Kimmeridge. Pay particular attention to the loose material on the foreshore, as these very often contain ammonites. Other fossils can also be found on the surface of large foreshore boulders; during our last visit we found a lovely Ichthyosaur tooth protruding from the surface.

Fossils can also be found to the west of the beach access point at Kimmeridge Bay. It takes about half an hour to navigate the rocky foreshore to reach the more productive coastal stretches.'
