Stratigraphy
Formation:Santa Cruz Member:Estancia La Costa
Stratigraphic resolution:formation
Stratigraphy comments: Dates from three levels in the lower one-third of the Santa Cruz fossiliferous beds at Monte Observación, rangebetween 16.42 Ma and 16.18 Ma and between 16.56 Ma and 16.28 Ma at Monte León. The dates are not wholly concordant but permit the assignment of the bulk of the coastal Santacrucian faunas to the late–early Miocene

Kay et al 2008: This list will expand as previously collected specimens are prepared and with future collecting. At the moment, this faunal listfits within the Santacrucian SALMA (Marshall, 1976; Marshall et al., 1983).
Lithology and environment
Primary lithology:green silty,sandy claystone
Includes fossils?Y
Lithology description: Greenish silty clay. In places, the clay is finely laminated — some layers have ripple marks and others are carbon-rich. Elsewhere, it is bioturbated, preserving calcified root casts, and has poorly defined bedding. The Campo Barranca fossil level is composed of a silty clay, greenish in color. In places, the clay is finely lami- nated—some layers have ripple marks and others are car- bon-rich. Elsewhere, it is bioturbated, preserving calcified root casts, and has poorly defined bedding.
Environment:terrestrial indet.
