Where: Chile (50.7° S, 72.5° W: paleocoordinates 51.4° S, 66.8° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Las Flores Formation, Santacrucian (17.5 - 16.3 Ma)
• The continental mammals would belong to the 160m thick Las Flores Formation (Cecioni, in Hoffstetter et, al. 1957, p. 188), which is apparently equivalent to the Santa Cruz Formation (upper lower Miocene) of the adjacent region , near Lake Argentino (see Furque, 1973 and point 7. below). In this area a geological study must also be carried out.
• formation-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size classes: macrofossils, mesofossils, microfossils
Collection methods: Mr. Osear Vidal, owner of the La Cumbre ranch, located along the Chilean-Argentine border, about 115 km north of Puerto Natales, has formed a large personal collection of fossils
