Where: San Jose, Uruguay (34.6° S, 57.0° W: paleocoordinates 34.6° S, 54.8° W)
• coordinate stated in text
When: Camacho Formation, Huayquerian (9.0 - 6.8 Ma)
• In Arazati the sediments of the Camacho Formation represent the first 2–5 m of the base of the cliffs and the exposed littoral platform at sea level (Perea and Martinez 2004; Sprechmann et al. 2000). Field observations indicate that the sediments continue into the Rio de La Plata, although the extent and thickness under the surface of the water are unknown (Sprechmann et al. 2000).
Environment/lithology: estuary or bay; lithified, sandy mudstone
Size class: macrofossils
• Posterior part of the skull (MNHN 2521), Right occipital region (MNHN 2521, reversed side), Right auditory region (MNHN 2521), Atlas (MNHN 2521), right P4–M3 (MNHN 2521)
