3 km south of Agrio del Medio (Candeleros Fm.) (Cretaceous of Argentina)

Also known as Rayososaurus type

Where: Neuquén, Argentina (38.4° S, 69.9° W: paleocoordinates 45.4° S, 46.2° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Candeleros Formation (Neuquén Group), Early/Lower Cenomanian (99.6 - 93.5 Ma)

• upper part of Candeleros Fm (formerly Rincón Member of Rayoso Formation)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; poorly lithified, coarse-grained, intraclastic, red, muddy sandstone

• "medium grained red sandstone"; "coarse-grained to sabulitic, quartzolithic sandstone (grain size between 1.5 and 3.0 mm), poorly consolidated, with subangular to subrounded clasts, a low degree of sphericity, and moderate to poor sorting. Exceptionally, lithic clasts can be observed of up to 6 mm in their main axis. The sediment displays open packing with a chaotic arrangement of its grains and a marked proportion of muddy matrix. It has a moderate reddish orange colour (10R 6/ 6)"

Size class: macrofossils
