North Wales is well known for its Carboniferous Limestone, which yields a range of marine fossils including corals, brachiopods, and crinoids. These deposits are widely exposed across both coastal and inland locations.
Anglesey is one of the most popular areas for collecting, with notable sites at Caim and Great Orme’s Head providing access to fossil-bearing strata. Although the limestone can be hard and difficult to work, coral pebbles can often be collected more easily from beach deposits.
Some locations also include Carboniferous shales, which can yield brachiopods more readily. A mixture of outcrops, scree slopes, and coastal exposures provides varied opportunities for fossil collecting across the region.
