Buchardt and Simonarson's Tjornes bed 19 (Pliocene of Iceland)

Also known as Bardarson's Tjornes bed 19

Where: Iceland (66.0° N, 17.0° W: paleocoordinates 66.0° N, 16.9° W)

• coordinate stated in text

• local area-level geographic resolution

When: Breidavik Group, Late/Upper Pliocene (3.6 - 2.6 Ma)

• Thick sequence of alternating terrestrial and marine sediments and interbedded lava flows of Pliocene and Pleistocene age; mostly fossiliferous marine sandstone with intermittent terrestrial or estuarine lignite beds and muddy sandstone; from Serripes biozone

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; unlithified sandstone

• Near intersection of the axial zone of rifting and volcanism and the Tjornes Fracture Zone; described as horst; tectonically active in the Pliocene-Pleistocene
• Sandstone with intermittent lignite beds and muddy sandstone

Size class: macrofossils

Preservation: original aragonite, replaced with calcite

Collection methods: quarrying,

• Only target species were collected (mainly Arctica islandica/Pygocardia rustica)
