Cañada del Pichanal (Cretaceous to of Argentina)

Where: Mendoza, Argentina (34.1° S, 68.9° W: paleocoordinates 40.1° S, 46.8° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Cerro Lisandro Formation, Middle Turonian to Middle Turonian (94.3 - 89.3 Ma)

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; massive, red mudstone

• The sequence represents a muddy floodplain where clay sediments accumulated in ephemeral bodies of water. In some areas there are reactivation surfaces (lag deposits) that represent episodes of flooding, drying, and reworking.
• The dominant facies are massive and laminated red-purple mudstones. The presence of clay minerals is easily recognizable by flooded soils and sparse vegetation. The facies association includes massive mudstones and thin, lenticular gray

•shales and sandstones. Fibrous gypsum beds are also common.

Size class: macrofossils

Collection methods: Collected during the development of the mining project ‘Proyecto Potasio Río Colorado’ (Vale S.A.)
