2 km southeast of Cinco Saltos cemetery, facies 1 [MUCP] (Cretaceous to of Argentina)

Where: Río Negro, Argentina (38.8° S, 68.0° W: paleocoordinates 41.8° S, 52.7° W)

• coordinate estimated from map

• small collection-level geographic resolution

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

• Río Colorado subgroup

• bed-level stratigraphic resolution

Environment/lithology: coarse channel fill; medium-grained, coarse, white, conglomeratic mudstone and concretionary, green, red, carbonaceous sandstone

• Facies 1: channel-fill deposits; facies 2: floodplain deposits; both within a meadering river system.
• Bones found in two facies: "1) trough cross stratified sandstones; and 2) red mudstones. Facies 1 is composed of pale yellow to whitish conglomeratic sandstones and sandstones that vary in thickness from 2 to 4 m. The conglomerates grade upward into coarse sandstones. Fine grained, medium bedded, lithic conglomerates and medium to coarse grained lithic sandstones are present. The trough cross bedding is well developed and bet set thicknesses vary from 0.30 to 0.10 m...Facies 2 is composed mainly of thinly bedded red and green mudstones; carbonate nodules are common."

Size class: macrofossils
