Winter Hill, Gastrioceras cumbriense Marine Band, shale Unit 2 (Carboniferous to of the United Kingdom)

Also known as Winter Hill, Gastrioceras cumbriense Marine Band, shale Unit 2, the advance shales

Where: England, United Kingdom (53.6° N, 2.4° W: paleocoordinates 1.2° S, 6.2° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Namurian Series Formation, Pendleian to Pendleian (326.4 - 314.6 Ma)

• The Gastrioceras cumbriense Marine Band generally does not exceed 60cm in thickness. The band is split into five units, the lower barren shales (Unit 1), the advance shales (Unit 2), the acme shales (Unit 3), the retreat shales (Unit 4), and the upper barren shales (Unit 5).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified shale

• Unit 2: The thickest and most complete sequence of faunal phases occurs at Winter Hill. Palaeoniscid fish scales appear at the base of the band and are joined 0.28 m higher up by Lingula mytilloides. At a distance of 70mm above this a goniatite / pectinoid community occurs, accompanied by Obiculoidea cf. nitida. [from Figure 1, wavy undulating shale with some pyrite blebs.]

Size class: macrofossils
