Great post of particular interest as I live in the much older greywacke range of the Scottish Southern Uplands (Silurian and Ordovician, raised by the Caledonian Orogeny). Not entirely fossil free as the graptolites here were used by Charles Lapworth to define the Ordovician itself. Great photo of a real greywacke mountain! Ours are just hills.
Given that our two continents have so recently separated, Avalonia ribbon also forms old England as well as New.
