Also known as Cerro Blanco
Where: Chubut, Argentina (44.5° S, 68.5° W: paleocoordinates 46.3° S, 59.9° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Early/Lower Oligocene (33.9 - 28.4 Ma)
• Likely pertains to Tinguirirican SALMA
Environment/lithology: terrestrial; lithology not reported
Size class: macrofossils
Reposited in the MLP
• Collected by Santiago Roth, this locality has never been relocated. It was thought to represent a mixed Mustersan-Deseadan fauna, but has subsequently been shown to pertain primarily to the recently described Tinguirirican SALMA (with perhaps some mixing of older taxa).
