Sandwich Bluff, Cape Lamb (SBM 8) (Cretaceous of Antarctica)

Also known as Vega Island

Where: Antarctica (63.9° S, 57.6° W: paleocoordinates 62.2° S, 68.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Sandwich Bluff Member (López de Bertodano Formation), Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• We tentatively assigned the specimens to the horizon SBM8, however, it cannot be ruled out that the specimens may have rolled down from upper strata (particularly horizons SBM11 and SBM 12)

• bed-level stratigraphic resolution

Environment/lithology: marine; shale

• poorly indurated siltstone

Size class: macrofossils
