Huayquerías de Biluco (Miocene to of Argentina)

Also known as Agua de la Concha at the foot of Cerro Torrecitas

Where: Mendoza, Argentina (33.8° S, 68.5° W: paleocoordinates 34.0° S, 66.6° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Late/Upper Miocene to Late/Upper Miocene (11.6 - 2.6 Ma)

• The Tunuyán (nominally Pliocene) and the Huayquerías (nominally Late Miocene) formations both outcrop in this area (Yrigoyen, 1994). In addition, the sediment associated with MACN-PV 8463, a tuffaceous sandstone with fine-grained, immature epiclasts formed by quartz, hornblende, and other inclusions that react strongly to HCl, is more reminiscent of the Tunuyán Formation than the HF (A.C. Garrido, personal commun., 2015).

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; tuffaceous sandstone

• tuffaceous sandstone

Size class: macrofossils
