Mollusc species from Norre Vissing, clay-pit of Galten Brickworks, Denmark (Oligocene of Denmark)

Where: Jylland, Denmark (56.2° N, 9.8° E: paleocoordinates 56.0° N, 6.5° E)

When: Chattian B zone, Brejning Clay Formation, Chattian (28.1 - 23.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; glauconitic, phosphatic, silty lime mudstone

• unit 2 (0.00-1.75m)

a sharp boundary, indicating an erosional unconformity, separates units 1 and 2. the interval 0.00-0.70 m is a homogeneous, silty mud of dark brown color (10 yr 2/2). no burrows were observed. at the base black phosphorites (maximum size about 6 cm) are frequent; some glaucontite is present in the sediment. the interval 0.70-0.90 m is a green, strongly glaucontitic sand with pyrite and phosphorites, overlain from 0.90 to 1.70 m by a silty mud with upwards increasing glauconite content. from 1.70 to 1.75 m a glauconitic snad is present with rather small phosphorites (1-2 cm) and pyrite-filled burrows. macrofossils are common in unit 2, but for the greater part irregularly distributed in pockets. the molluscan treated in this paper originates especially from the interval 0.00-0.70 m, in which large specimens have been collected. in the interval 0.70-0.90 m thin-shelled bivalves are frequent. the number of fossils decreases upwards, where the shells often are decalcified as a result of pyrite oxidation, resulting in a preservation as casts or moulds.

Preservation: cast, original aragonite
