El Zampal section - Huincul Formation (Cretaceous of Argentina)

Where: Mendoza, Argentina (36.5° S, 69.7° W: paleocoordinates 43.6° S, 45.9° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Huincul Formation (Neuquén Group), Late/Upper Cenomanian (99.6 - 93.5 Ma)

• formation-level stratigraphic resolution

Environment/lithology: fluvial; lithified, green, muddy mudstone and lithified, gray, yellow, sandy sandstone

• Vallati 2001: The sedimentary characters of the studied unit suggest a fluvial environment of considerable energy.

• This section includes massive grey and yellowish brown sandstones, interbedded with mudstones, siltstones and purple sandstones. Within this interval, the dark green mudstone beds yielded well preserved palynomorphs

Size class: microfossils

• Other = palynomorphs

Preservation: soft parts, original sporopollenin

Collected by Universidad Nacional de la Patagonia San Juan Bosco(UNPSJB)

Collection methods: bulk, chemical, hydrochloric, hydroflouric,

• UNPSJB: Repository
