†Homunculus patagonicus (Homunculidae)
Homunculus patagonicus ist eine Primatenart innerhalb der Familie Homunculidae, die ab dem Neogen (Miozän) im Burdigalium lebte, das vor rund 20,4 Millionen Jahren begann und bis vor 16 Millionen Jahren andauerte.

| Killik Aike Norte | "Killik Aike Norte [basis of coordinate]... exposed in the northern cliffs of the estuary of the Rio Gallegos river" At present, Killik Aike Norte is called both the farm and the fossiliferous quality (Marshall, 1976; Tauber, 1994). | Burdigalian zwischen 16.3 und 17.5 Millionen Jahren |

| the fossiliferous tuff yielded 40Ar/39Ar ages of 16.45 +/- 0.14, 16.5 +/- 0.2, and 16.5 +/- 0.3 Ma based on "laser incremental-heating analyses of plagioclase" Gonzalez and Scilalto-Yané 2008: The Santa Cruz Formation on this site emerges along the canyons of the Gallegos River estuary. Tauber et al. (2004) identified three fossiliferous levels in Killik Aike Norte, so we are not sure of the exact level of provenance of the mentioned findings. It should be noted that the KAN 2 level is the most accessible and rich in fossils; however, a large number of fallen blocks of the upper strata with fossils are also found at this level (Tauber et al., 2005). These authors tentatively correlate the KAN 2 level with the fossil level 6, which emerges in the intertidal zone, in front of Corriguen Aike (Estancia de La Estancia La Costa) and in the southern sector of Cañadón Silva (Tauber, 1994). If this is correct, the origin of the YPM PU 15611, YPM PU 15565 and MPM-PV 1811 materials would not be below the fossiliferous level 6, that is, it would correspond to the higher levels of Protypotherium attenuatum Biozone 1 , in the Estancia La Costa Member (Tauber et al., 2004). | vitric [volcanic] tuff |

| Dates from three levels in the lower one-third of the Santa Cruz fossiliferous beds at Monte Observación, rangebetween 16.42 Ma and 16.18 Ma and between 16.56 Ma and 16.28 Ma at Monte León. The dates are not wholly concordant but permit the assignment of the bulk of the coastal Santacrucian faunas to the late–early Miocene | tuffaceous silty sands, andgreenish silty clays. |

| The age of this level is between 17.3 and 17.6 Ma, based on the age of two radiometrically dated tuffs that bracket it: the CO tuff of Perkins et al. (2012) and the CV-13 tuff of Trayler et al. (2020). The former as refined by high-precision U–Pb age modeling is 17.31 Ma and the latter is 17.62 Ma (Trayler et al., 2020). |
