Arenig – Llanvirn
The GCR sites selected for this GCR Block represent the British geological record of Earth history from about 483 to 460 million years ago (Ma), as represented by the rocks deposited during the second and third epochs of the Ordovician Period (495–440 Ma), which is the second period of the Palaeozoic Era (545 to 251 Ma).
More information on this block is provided in the Arenig - Llanvirn block description.
