Villavil (Chiquimil - El Jarillal med) (Neogene of Argentina)

Where: Catamarca, Argentina (27.1° S, 66.8° W: paleocoordinates 27.3° S, 64.8° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: El Jarillal Member (Chiquimil Formation), Huayquerian (8.0 - 5.0 Ma)

• In Figure 3 they sum up the chronobiostratigraphy of locality Puerta de Corral Quemade and locality Villavil. Information about this locality (age, geology etc) mostly come from this figure.

•*dataciones absolutas de Latorre et al. (1997) (Date based on study on d13C and d18O.)** datación ab- soluta de Sasso (1997); las edades de la columna Ma son asignadas de acuerdo a la tasa de sedimentación

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; conglomeratic sandstone

• The environment proposed for El Jarillal Member (Chiquimil Formation) and lower levels of the Andalhuala Formations is savanna- like, with small forests and a wet season with a progressive aridification toward the top of the Andalhuala Formation.

Size class: macrofossils
