Kambsgja (Tjornes Horizon 19 main) (Pleistocene of Iceland)

Where: Iceland (66.2° N, 17.2° W: paleocoordinates 66.2° N, 17.1° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Pleistocene (2.6 - 0.0 Ma)

• Horizon 19 within the Serripes Zone of the Tjornes Sequence in Bardarson's Horizons.

Environment/lithology: shallow subtidal; sandstone

• Deposits probably formed in very shallow water. They are most likely intertidal swash zone deposits or subtidal channel deposits.

Collection methods: bulk

• Samples of 2-3kg were taken in Baroarson's horizons. Quantitative mollusc analyses were carried out on about 1kg of each sample by picking apart the material.
