Distribution of GCR sites of GCR block Ludlow

The GCR sites selected for this GCR Block represent the British geological record of Earth history from about 423 to 419 million years ago (Ma). This interval is the third epoch of the the Silurian Period (440 to 410 Ma).

Rocks that formed during the Ludlow Epoch form the the Ludlow Series (part of the Silurian System). The Silurian System is divided into four series (Llandovery (see LDY), Wenlock (see WEN), Ludlow and Prídolí (see PRIDOL)) and all but one series (the Pridoli) into a number of stages. The Ludlow Epoch is divided into two ages.

Of the eight stratotypes that define the bases to the Silurian stratigraphical divisions, seven are in Britain. The one exception is the base to the Prídolí Series. The chosen level for the base of the Devonian System in the Czech Republic is considerably higher than the base of the ‘Old Red Sandstone’ which had traditionally been regarded as the Silurian–Devonian boundary in the Welsh Borderland. The new Prídolí Series therefore correlates with the lowest part of the ‘Old Red Sandstone’ (see NMAR-DEV). Graptolites and conodonts have yielded the most refined Silurian zonations, but analogous schemes exist for other groups, notably brachiopods, acritarchs and chitinozoans.

For discussion of Silurian palaeogeography and palaeontology, see LDY.
