Where: Antarctica (64.2° S, 56.6° W: paleocoordinates 64.3° S, 58.5° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Unit III Member (La Meseta Formation), Priabonian (38.0 - 33.9 Ma)

• La Meseta Unit III of Zinsmeister and Camacho (1982); Submeseta according to Reguero et al., 2013

•Strontium dating indicates Telm 7 to have been deposited between 39.1 and 34.0 Ma [148]. Samples from near the top of the formation fall closest to the presumed fossil horizon [145, 147], thus indicating an age of 34.2–34.0 Ma [148, 149]. (Marx & Fordyce, 2015)
