Sierra Barrosa (Anacleto) [MCF] (Cretaceous to of Argentina)

Also known as ACDP

Where: Neuquén, Argentina (38.8° S, 68.8° W: paleocoordinates 41.7° S, 53.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Anacleto Formation (Neuquén Group), Early/Lower Campanian to Early/Lower Campanian (83.5 - 70.6 Ma)

• lower part of formation

• bed-level stratigraphic resolution

Environment/lithology: fluvial; lenticular, bioturbated, medium-grained, coarse, red sandstone

• "reddish fluvial sandstones." "stacked, massive, medium-to-coarse-grained sandstone bodies with locally occurring extraformational particles, pebbles and cobbles. Sandstone bodies are typically sheet-shaped, but lenticular bodies occurlocally. Sediments are almost uniformly red in color, but some gray to yellow sandstones also occur. Sandstones are heavily bioturbated with localized occurrences of decimeter-scale, “lumpy” to vertically

•oriented calcareous concretions that preferentially cement Planolites burrow-fills, and a variety of more

•complex burrow/dwelling structures of unknown origin."

Size class: macrofossils

Collected by ACDP in 2001

Collection methods: quarrying, surface (in situ), mechanical,
