SSSI

Coed Cochion Quarry SSSI is a very small quarry of 0.4 hectares (0.99 acres) located approximately 1 mile (1.6 km) south of Llangynog and 1.3 miles (2.1 km) north of Llanybri, north-east of the Taf Estuary.[1][2]

The site is a rare example in the world of Precambrian fossil records - greater than 0.5 billion years old - found in the ashy siltstone sedimentary rock. A number of fossils of medusoid creatures - visually like, but maybe not in fact contemporary jellyfish - are present, as are feeding trails of other creatures. The evidence is that the site was once a sandy, silty shoreline in which soft-bodied fauna became buried.[2][3]
