Also known as Manse Burn Posidonia bed, Bed B of Clark, 1989

Where: Scotland, United Kingdom (55.9° N, 4.3° W: paleocoordinates 0.9° S, 3.1° E)

• coordinate based on political unit

• small collection-level geographic resolution

When: Posidonia Member (Limestone Coal Formation), Serpukhovian (330.9 - 323.2 Ma)

• "Carboniferous (Serpukhovian)". The Limestone Coal Formation is sometimes treated as a synonym for the Manse Burn Formation

• member-level stratigraphic resolution

Preservation: adpression, replaced with pyrite
