Where: Santa Cruz, Argentina (50.7° S, 72.5° W: paleocoordinates 53.2° S, 62.7° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Río Baguales Formation, Lutetian to Lutetian (47.8 - 38.0 Ma)

• Reworked taxa of Early to Middle Eocene age, together with autochthonous deposited Middle to Late Eocene taxa. However, a subsequent SHRIMP date on detrital zircons from near the base of their measured section indicated a maximum age of 40.48 ± 0.37 Ma (Le Roux, 2012, Bostelmann et al., 2012), confirming at least a latest Lutetian to Bartonian age.

• bed-level stratigraphic resolution

Environment/lithology: estuary or bay; shale

Size classes: macrofossils, mesofossils
