Central Wales is well known for its Ordovician fossil sites, particularly those yielding trilobites from these ancient marine deposits. A number of locations expose fossil-rich strata, making the area important for collecting early Palaeozoic material.
Little Wern is one of the best-known sites, providing access to trilobite-bearing rocks, while nearby Bettws offers similar deposits, although specimens are often fragmentary. These locations are typically found in old quarries and exposed sections.
Additional sites across the region, including streams, cuttings, and natural outcrops, provide further opportunities to collect Ordovician fossils, making Central Wales a key area for trilobite collecting in the UK.
