Kuhnpasset B2335-26 (Cretaceous of Greenland)

Where: Greenland (74.5° N, 20.3° W: paleocoordinates 58.2° N, 12.8° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Kuhnpasset Formation, Late/Upper Barremian (130.0 - 125.5 Ma)

• bed-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, argillaceous, sandy reef rocks

• methane-based cold-seep complex with the vents occurring near the footwall crests o tilted fault blocks
• the mounds are construed of grey, unbedded, muddy to sandy limestone. Bedding has been homogenized, probably by burrowing activity. Within the mounds preferentially cemented tubular structures commonly occur. They probably represent the seep plumbing system.

Preservation: replaced with silica

Collection methods: mechanical,
