Agua de Cabrera Sur (Cretaceous of Argentina)

Where: Mendoza, Argentina (36.5° S, 69.5° W: paleocoordinates 36.5° S, 34.7° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: La Tosca Member (Huitrín Formation), Barremian (129.4 - 125.0 Ma)

• he present study focuses on repair scars recorded in gastropods from the La Tosca Member of the Huitrín Formation, the basal unit of the Bajada del Agrio Group.

Environment/lithology: coastal; marl

• All sedimentological and paleontological evidence suggests a similar setting likely subject to the same depositional processes and comparable environmental fluctuations across the study area. The marl bed represents soft bottoms in a low-energy, possibly lagoonal setting with salinity fluctuating between normal marine and meso-brachyhaline regimes
• The studied gastropods come from a thick marl bed (Facies C of Lazo et al., 2017) correlated among the three sections through lithology, fossil content, and relative stratigraphic position

Size class: macrofossils

Preservation: cast

Collection methods: The material is housed in the Museo de Ciencias Naturales y Antropológicas Juan Cornelio Moyano, Colección de Paleontología de Invertebrados (MCNAM-PI), Mendoza, Mendoza province, Argentina, under the repository numbers MCNAM-PI 24522, 24525, and 25004.
