Where: Neuquen, Argentina (38.3° S, 70.1° W)

• Paleocoordinates: 38.5° S, 29.9° W (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Weavericeras vacaense ammonoid zone, Lower Agrio Member (Agrio Formation), Early/Lower Hauterivian (136.4 - 130.0 Ma)

• From near top of section (0.5 m thick). From Weavericeras vacaense zone, Lower Agrio Member, Agrio Formation, early Hauterivian.
