Perfil Quebrada Don Nielsen (QDN-13) (Cretaceous of Argentina)

Where: Santa Cruz, Argentina (49.5° S, 71.5° W: paleocoordinates 53.7° S, 41.5° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Piedra Clavada Formation, Early/Lower Albian (112.0 - 109.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: deltaic; lithified, black, muddy shale and lithified, yellow, sandy sandstone

• In general, it is very clear that the trace fossils and invertebrates are essentially marine, which suggests, together with its sedimentary facies, a deltaic zone submerged in prodelta facies, deltaic front, interdistributary bays and interdistributary channels, and shoreface-beach facies.
• The Piedra Clavada Formation is composed by yellow sandstones, gray to dark mudstones, heterolithic facies and few conglomerates and coquinas.

Size class: microfossils

• Other: palynomorphs

Preservation: soft parts, original sporopollenin
