Lithological indicators of climate, such as coals, evaporites, bauxites, and tillites,can be used to map the past position of the major climatic zones (Humid Tropics, Dry Subtropics, Warm and Cool Temperate, and Polar) that crossed the supercontinent

It is now recognized that the late Telychian and early Gorstian sea level changes are, like many others in the Silurian, of world‐wide extent. The 30–50 m deepening events at these times were between 1 and 2 Ma in duration, so melting continental

The description of brachiopod communities in the Wenlock of Wales and the Welsh Borderland permits interpretation of local marine environments. Graptolites and evolving lineages of brachiopods (notably Resserella sabrinae subspecies) allow the beds i

The Skomer Volcanic Group (previously thought to be of Lower Ordovician age) grades upward and laterally into sediments containing Lower Silurian faunas. Ostracods of late Ordovician or Silurian age have been found on Midland Island in beds interstra
