Where: Catamarca, Argentina (27.4° S, 66.9° W: paleocoordinates 27.6° S, 64.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: El Áspero Member (Chiquimil Formation), Tortonian (11.6 - 7.2 Ma)

• Amelia and Bonini 2020: The fossil studied in this contribution comes from facies of reddish and greyish massive sandstones, often interbedded by parallel laminated sandstone with calcretes and rhizoconcretions, assigned to the El Áspero Member, Chiquimil Formation (Fig. 1C). Concerning to chronological aspects, the El Áspero Member was dated from the andesitic intrusive bodies that crop out near the Villavil locality, approximately 30 km NW of the WSCP (Fig. 1C), and yield an age of 9.14 ± 0.09 Ma (Sasso, 1997). Therefore, an age of approximately 9 Ma (i.e., early late Miocene, Tortonian, sensu International Chronostratigraphic Chart, ICC; Cohen et al., 2013) is herein proposed for the time of deposition of the fossiliferous levels in the El Áspero Member in WSCP.
