Where: Brazil (32.2° S, 52.2° W: paleocoordinates 32.2° S, 52.2° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Late/Upper Pleistocene (0.1 - 0.0 Ma)
• STRATIGRAPHIC RELATIONS: Unknown lithostratigraphic unit. THICKNESS: From drill hole of at least 231 m thick, from 27 m thick unit. AGE: Stated to be Holocene, based of faunal similarity with Uruguan and Argentinian Holocene assemblages, although similarity with Pleistocene of these regions also discussed. Assigned here to Late Pleistocene based of depth in core. STRATIGRAPHIC POSITION: From 177-204 m in drill hole.
