Where: Argentina (39.6° S, 60.7° W: paleocoordinates 39.7° S, 58.3° W)

• coordinate stated in text

When: Barranca Formation, Late/Upper Miocene to Late/Upper Miocene (11.6 - 3.6 Ma)

• The specimens studied were recovered from Neogene marine deposits in the Colorado Basin, Argentina. The fossil material was extracted from cutting samples taken from well Cx-1 of the Colorado Basin from the 200-530 m stratigraphical interval. Based on dinoflagellate cysts and sporomorph assemblages, proposed a Late Miocene-Early Pliocene age for the 200-530 interval.

Environment/lithology: shallow subtidal; lithified, glauconitic, silty sandstone
