Where: Chubut, Argentina (45.4° S, 68.0° W)

• Paleocoordinates: 45.6° S, 61.9° W (Wright 2013)

• coordinate estimated from map

When: Sarmiento Formation, Middle Eocene to Middle Eocene (47.8 - 16.0 Ma)

• Indeterminate levels of the middle Eocene–lower Miocene Sarmiento Formation

•

•We note here that this locality where Carlos Ameghino collected the fossils was erro- neously assigned to the no longer existing Río Chico Formation in previous reports and its age was also mistakenly assigned to the Riochican mammal age (Agnolin 2017). An updated stratigraphical scheme can be found in Raigemborn et al. (2010) and Woodburne et al. (2014), and a further explanation about this locality can be found in Picasso et al. (2022).
