Paleocoordinates:	50.4° South, 66.9° West (Wright 2013)
Basis of coordinate:	stated in text
Altitude:	0 meters
Geographic resolution:	local area

Period:	Neogene	Epoch:	Miocene
Stage:	Burdigalian	10 m.y. bin:	Cenozoic 5
Key time interval:	Santacrucian
Age range of interval:	17.5 - 16.3 m.y. ago

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).

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.

Modes of preservation:	body
Size of fossils:	macrofossils

Collection methods:	field collection
Reason for describing collection:	paleoecologic analysis
