Sudurnes Sample 2 (Pleistocene of Iceland)

Where: Iceland (64.2° N, 22.0° W: paleocoordinates 64.2° N, 22.0° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• 3 meter above sea level, horizon S2 within glacial marine deposit (no formation given)

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; unlithified, pebbly, sandy siliciclastic sediments

• glaciomarine deposit, deposited when glacier is in retreat
• Lenses with marine fossils, gravel with sand

Taxonomic list

• appears complete, with molluscs, barnacles, echinoids, and ostracods noted.

•Unlike other collections in maunscript, forams not noted.

•Abundance counts determined as follows:

•whole gastropod shells and fragments with the top of the spire preserved were counted as individuals; valves (left or right) and umbonal fragments were counted and their number divided by 2. parietal plates of barnacles were counted and their number divided by 6 when dealing with Balanus and 4 when dealing with Verruca
