Where: Chile (47.0° S, 72.4° W: paleocoordinates 47.9° S, 66.1° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Guadal Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Guadal Fm, which is overlain by the Galera Fm (Early-Middle Miocene). AGE: Late Oligocene-Early Miocene in text. Composition of the fauna reveals close similarity with those of the Patagoniano, and in particular the Monte Leon Fm. An Early Miocene age could be moe precise on the basis of sequence stratigraphic events. Early Miocene is assigned here. STRATIGRAPHIC POSITION: From upper part of the Guadal Formation.

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, gray sandstone

Size class: macrofossils

Preservation: cast, mold/impression

Collected by Frassinetti & Covacevich in 1986-1988

Collection methods: surface (in situ),

• COLLECTOR: Presumably Frassinetti, C., and Covacevich, C. (1986-1988). REPOSITORY: Museo Nacional de Historia Natural, Santiago, Chile
