Hualtarán, Quebrada Larga (Cretaceous of Argentina)

Where: San Luis, Argentina (32.5° S, 67.0° W: paleocoordinates 33.3° S, 34.0° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: La Cruz Formation (Gigante Group), Aptian (125.0 - 113.0 Ma)

• pre-dates the Albian Lagarcitos Fm. & listed as Aptian by Codorniu & Gasparini (2007); fossils in upper third of La Cruz Fm.

• bed-level stratigraphic resolution

Environment/lithology: alluvial fan; fine-grained, green, argillaceous sandstone and conglomerate

• "The paleoenvironment of the La Cruz environment suggests low transport and chaotic deposition, probably related to high density flows of the alluvial type"
• "greenish sandstones"; "fine argillaceous sands, intercalated between conglomerate deposits"

Size class: macrofossils
