Where: Scotland, United Kingdom (57.3° N, 2.8° W: paleocoordinates 22.4° S, 6.5° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Dryden Flags Formation, Pragian (410.8 - 407.6 Ma)
• The Rhynie and Windyfield cherts found at Rhynie, Aberdeenshire, Scotland, both occurring in the Dryden Flags Formation (Rice et al. 2002), represent the surface expression of a metaliferous hydrothermal system that was active in the Rhynie area during the early Devonian (Pragian: Rice et al. 1995, 2002). The Windyfield chert is slightly higher in the stratigraphic succession than the latter and comprises laterally discontinuous lenticular, pod-like bodies of chert interbedded with hydrothermally altered shales and sandstones.
