Pettycur, Pettycur Cliff, Ashy Limestone 1 (Carboniferous of the United Kingdom)

Where: Scotland, United Kingdom (56.1° N, 3.2° W: paleocoordinates 3.9° S, 0.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Pettycur Volcanics Formation (Upper Oil Shale Group), Asbian (339.4 - 336.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; tuffaceous limestone

• The Pettycur cliff section is composed of three basaltic lava flows with a shale separating the lower two. It is at the base of the third basaltic lava that the plants occur within ashy limestone blocks up to 80 x 50 cm; these are usually sub-angular but the margins are often obscured by the lava matrix. Two different lithologies were recovered from the cliff: the zygopterid limestone and a series of ashy limestones [including this collection] all containing permineralized and fusainized plants.

Size classes: macrofossils, mesofossils, microfossils

Preservation: permineralized, charcoalification

Collection methods: surface (in situ), chemical, mechanical, peel or thin section,
