Birdshill Quarry is a Site of Special Scientific Interest (SSSI) in Carmarthenshire, Wales. [1] [2]
Birdshill Quarry SSSI is located approximately 1.8 miles (2.9 km) west of Llandeilo, and covers 0.4 hectares (0.99 acres). [1] [2]
The SSSI citation for Birshill Quarry specifies the importance of the site to be the abundant fossils of trilobites, brachiopods and bivalves in an Ashgill Birdshill Limestone strata of the quarry, incorporated as deposits some 425 million years ago. The site has been dated by reference to microfossil conodonts found in the strata. [2]
A site of special scientific interest (SSSI) in Great Britain, or an area of special scientific interest (ASSI) in the Isle of Man and Northern Ireland, is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I".
