Pilton Shales Site I (Devonian of the United Kingdom)

Where: England, United Kingdom (51.1° N, 4.1° W)

• Paleocoordinates: 34.5° S, 13.6° W (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Wocklumeria ammonoid zone, A Member (Pilton Shales Formation), Late/Upper Famennian (365.2 - 358.9 Ma)

• Thought to be uppermost Devonian (Wocklumeria). Pilton A.

• member-level stratigraphic resolution

Environment/lithology: deltaic; shale and limestone

• "Shallow seas..." "The Pilton Mudstone Formation was therefore de- posited during a gradual transgression from terrestrial deltaic and shallow marine environments to more open marine conditions, as evidenced by the increased dom- inance of mudstones and the appearance of a normal marine fauna including trilobites, crinoids, goni- atites and brachiopods (Whittaker & Leveridge, 2011). Therefore, subunit A3 of the Pilton Mudstone Formation was deposited in a transgressive shallow marginal shelf sea setting, on the southern slope of the Avalo- nian Terrane about 30°S (southern part of the Laurussia megacontinent) within the Rheic Ocean (Golonka & Gawe ̨da,2012). Deltaic nearshore.
• "The shales, siltstones, thin sandstones and fossiliferous limestone lenses include thicker sandstones which commonly stand out as topographical features."

Size class: macrofossils
