Where: Salta, Argentina (25.5° S, 65.5° W: paleocoordinates 27.9° S, 56.3° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Casamayoran mammal zone, Lumbrera Formation (Salta Group), Middle Eocene (48.6 - 37.2 Ma)

• Upper unit of Santa Barbara subgroup of Salta Group

• member-level stratigraphic resolution

Environment/lithology: terrestrial; peloidal, red mudstone and red sandstone

• translated: Lumbrera Formation is characterized predominantly by red mudstones. It is approximately 410 m with 50 m of red, medium-grained, cross-stratified sandstone at the base. On top, it has the characteristics of brick-red pelites, which are finely to massively bedded, very fragmented, and fossil-bearing. Above the pelite is a calcareous sandstone with green and brown pelitic intercalations, above which is a fossil-bearing layer of red pelite.
