This site is designated due to its geological quality: Robeston Wathen Quarries SSSI has one special feature: Caradoc - Ashgill (late Ordovician) sedimentary rocks in disused quarries and a stream bed. In Wales, geological sites range from quarries to rocky outcrops and massive sea-cliffs.[citation needed] 30% of SSSIs in Wales are notified for geological and geomorphological features.[citation needed]
The sedimentary rocks of impure limestones, calcareous mudstones and black mudstones have yielded a variety of fossils which include evidence that the rocks are from the Caradoc – Ashgill stages - around 440 million years ago. The fossils also provide a means of correlation with other similar sites, and are catalogued by National Museum Wales.[2]
