MMH locality Su 216 (Cretaceous of Venezuela)

Also known as Bahía de Santa Fé

Where: Venezuela (9.0° N, 63.5° W: paleocoordinates 8.6° N, 31.5° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Morro Blanco Member (Barranquín Formation), Barremian (129.4 - 125.0 Ma)

• "[The material] was collected from several different limestone horizons of the Barranquin Fm. in the upper two-thirds of the section exposed at Santa Fe. There are almost 1000 meters of section between oldest and the youngest fossiliferous horizons. However, no zonation of species was noticed and the same forms that are present in the youngest horizon are found in the oldest fossil bed."

•JA: closest correlation is with "Neocomian or possibly Barremian" faunas of Europe, but because there "seems to be no hiatus between the Barranquín and the overlying Lower Aptian El Cantil formation, the Barranquín formation probably also represents the Barremian"

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified limestone

• "Under the special conditions prevalent along the sea coast within two or three meters of the strand line, the soft calcareous fossils are weathered out of the hard limestone matrix and are available in a remarkable state of preservation."

Collection methods: surface (in situ), mechanical,
